Nausea and Cramps After a Gastric Balloon: What Is Normal and When to Call Your Team

The third night is often the hardest. The sedation has long worn off, the hospital wristband is in the bin, and the person lying awake at two in the morning is not thinking about the months of weight loss they signed up for. They are thinking about the wave of queasiness that arrives every time they roll over, the tight cramp under the left rib, and one very specific question: is this what everyone feels, or is something wrong?

Both answers can be true on different nights, which is why gastric balloon side effects first week deserve a calmer, more detailed explanation than the leaflet usually gives. Your stomach has just been asked to share its space with a saline-filled sphere roughly the size of a grapefruit, and it responds the way any muscle does to a foreign object: it squeezes, complains and slowly adapts.

This article walks through what that adaptation looks like day by day, which symptoms are the body doing its job, and which ones should prompt you to pick up the phone before morning.

How a gastric balloon actually works, and why your stomach objects

An intragastric balloon is a soft silicone sphere placed in the stomach through the mouth and then filled with sterile salt water. There is no cutting and no change to your anatomy. According to Mayo Clinic, the balloon is placed during an endoscopy, a procedure in which a thin flexible tube with a camera is passed down the throat while you are sedated, and the whole placement usually takes around half an hour.

Once filled, the balloon occupies a large share of the stomach’s resting volume. That is the entire point. A stomach that is already partly full sends satiety signals to the brain sooner, so smaller meals feel like enough. The device also slows the emptying of food into the small intestine, which stretches out the feeling of fullness between meals.

Your stomach, however, did not agree to this arrangement. The stomach wall is layered muscle that contracts in rhythmic waves to grind food and push it onward. When those waves meet a smooth, heavy object that will not move along, the muscle keeps trying. That repeated squeezing is felt as cramping. Meanwhile, stretch receptors in the stomach lining report to the brainstem’s vomiting center that something large is present, and the brain answers with nausea, the body’s oldest way of saying: get rid of that.

Over days the stomach recalibrates. Stretch receptors become less sensitive to the constant pressure, the brainstem stops treating the balloon as an emergency, and the muscle settles into a new rhythm around the object. Mayo Clinic describes the balloon as a temporary device, generally left in place for about six months before it is deflated and removed by endoscopy. The rough first week is the price of admission, not a sign the procedure has gone wrong.

Gastric balloon side effects first week: what most people actually feel

The honest picture is uncomfortable but predictable. Mayo Clinic reports that pain and nausea affect about one third of people soon after balloon insertion, and that these symptoms usually last only a few days. Some clinicians and patients would say the true share who feel at least some queasiness is higher; the one-in-three figure refers to symptoms significant enough to be recorded.

Nausea typically leads the way, often starting within hours as the sedation fades. It tends to come in waves rather than as a steady state, and many people notice it is worst on an empty stomach in the morning and again when they try to lie flat at night. Vomiting is common in the first two to three days, especially if liquids are taken too quickly or in large gulps.

Cramping usually sits high in the abdomen, under the ribs or behind the breastbone, and is frequently described as a tight, gripping ache that builds, holds for a minute or so, and releases. A separate, duller sensation of pressure or fullness is nearly universal and is simply the weight of the balloon resting against the stomach wall.

Other early companions include belching, a sour taste from acid reflux, bloating, mild back or shoulder discomfort from referred stomach pain, and profound tiredness. Reduced appetite is the intended effect, though in the first week it can feel more like an active aversion to food than a gentle lack of interest.

What distinguishes normal adaptation from trouble is the direction of travel. Ordinary gastric balloon side effects in the first week are worst early and then flatten out. Symptoms that were improving and then sharply worsen, or that fail to budge at all after several days, deserve a conversation with your team rather than more waiting.

Gastric balloon nausea: how long does it usually last?

Most people want a number, and the most defensible one comes from Mayo Clinic: nausea and pain after placement usually last only a few days. In practice, teams tend to describe a peak within the first 48 to 72 hours, followed by steady improvement so that by the end of the first week most people are managing liquids and soft foods with only occasional queasiness. A smaller group takes closer to two weeks to feel settled. The figures are typical ranges, not guarantees, and your own curve depends on factors your team can discuss with you.

Why does it fade? Three mechanisms work in parallel. First, stretch receptors in the stomach wall down-regulate when pressure is constant, much as the sensation of a wristwatch disappears within a day of wearing it. Second, the stomach muscle stops attempting to propel the balloon onward and instead accommodates it, so fewer signals reach the brainstem. Third, the medicines your team prescribed for the early days, if any, quiet the vomiting reflex while adaptation happens.

Nausea that persists beyond two weeks is not automatically a complication, but it does warrant review. Possible reasons include the balloon being too large for a particular stomach, an inflamed stomach lining, or simply slower adaptation. The NHS notes that persistent nausea in general should be checked by a clinician, and that advice applies with more force when a device is involved.

The early days also shape how people remember the whole experience. Those who expected a fully comfortable week often feel that something has failed by day two. Those who were told plainly that the first 72 hours would be rough tend to weather them with more patience. Knowing the typical arc will not make the nausea disappear, but it does turn a frightening unknown into a countdown.

Stomach cramps after gastric balloon: what is behind the pain

Cramping is mechanical before it is anything else. The stomach’s muscular wall contracts in coordinated waves called peristalsis, the same rolling motion that moves food through the entire digestive tract. With a balloon present, those waves push against an object that does not yield or move along. Each frustrated contraction is felt as a gripping, wringing ache, usually in the upper abdomen just below the ribs.

Several features make these cramps recognizably benign. They tend to come in cycles rather than being constant. They often intensify after swallowing liquid, because the stomach responds to any new arrival by contracting. They ease when you sit upright and breathe slowly, and they gradually lose intensity across the week as the muscle adapts to the balloon’s presence. Many people notice they can predict the cramp a few seconds before it arrives, which is oddly reassuring.

A second contributor is gas. Swallowed air and fermentation from a changed diet collect above and around the balloon, and pockets of gas stretch the stomach wall from the inside. This produces bloating and sharp, shifting pains that often relieve with a belch. Sipping slowly and avoiding straws and carbonated drinks reduces the volume of air arriving in the first place.

Referred pain adds a third layer. The stomach shares nerve pathways with the diaphragm and the left shoulder, so irritation of the stomach lining can be felt as an ache in the shoulder blade or upper back. It is unnerving if you are not expecting it, and worth mentioning to your team so they can confirm it fits the usual pattern.

The cramps that concern clinicians behave differently: constant rather than cyclical, severe rather than gripping, spreading across the whole abdomen, or arriving with fever, a rigid belly or vomiting that will not stop. Those patterns are covered in the red-flag section later, and they are the reason your team gives you a number to call.

Who a gastric balloon is usually for, and who is usually asked to wait

Body mass index, or BMI, is a ratio of weight to height used to estimate body fatness. Mayo Clinic describes the intragastric balloon as an option generally considered for adults with a BMI between 30 and 40 who have not achieved lasting results with diet and exercise changes, and who are willing to commit to a supervised program of lifestyle change alongside the device. The balloon is a tool inside a program, not a replacement for one, and the NHS is clear that all weight-loss interventions work best with long-term support around eating and activity.

Suitability is not only about the number on the scale. Teams look at whether the stomach is structurally able to host the balloon and whether the person can tolerate the early weeks. People with a large hiatus hernia, in which part of the stomach pushes up through the diaphragm, or with previous stomach surgery, may be advised against the device because the anatomy raises the risk of the balloon causing damage or failing to work as intended.

Active stomach or duodenal ulcers, inflammatory bowel conditions affecting the upper gut, and bleeding disorders are typical reasons a team may suggest waiting or choosing another route. Pregnancy, or plans to become pregnant during the months the balloon is in place, is another; the device is removed before or in early pregnancy in most protocols. Some medicines that irritate the stomach lining or affect clotting need review before the balloon is considered, and that review sits with the prescribing clinician, not with the patient alone.

Finally, teams weigh readiness. A person who cannot arrange time off in the first week, who lives far from help, or who is going through a period of significant stress may be asked to postpone, not because the balloon is unsuitable but because the adaptation period needs attention and support. These are individual judgments, made together with the treating team.

Gastric balloon recovery timeline: the first two weeks at a glance

Timelines vary between people and programs, but a typical arc drawn from Mayo Clinic’s description of early symptoms lasting a few days, and from the liquid-to-soft-food progression most teams use, looks like this. Treat the table as a map of the usual terrain rather than a schedule to hit.

Period	What is common	What usually helps
Day of placement	Sedation drowsiness, sore throat, nausea beginning within hours, sense of heavy fullness	Rest, small sips of clear liquid as advised, sitting upright
Days 1 to 3	Peak nausea and cramping, some vomiting, belching, fatigue, poor sleep	Prescribed anti-nausea medicines as directed, sips every 10 to 15 minutes, warm rather than cold drinks for some people
Days 4 to 7	Symptoms flatten; nausea more occasional, cramps shorter, appetite low	Gradual move to full liquids or purées if the team allows, gentle walking
Days 8 to 14	Most people tolerate soft foods; reflux or bloating may linger	Small, slow meals; separating drinking from eating; follow-up call or visit

Two patterns cut across every row. The first is that improvement is rarely a straight line. A good day four followed by a queasy day five is ordinary, particularly if the better day tempted you to eat or drink faster. The second is that the whole picture should be trending toward comfort by the end of week one. If your personal timeline is running well behind this table, that is not a failure but it is a reason to check in, since your team may adjust medicines, dietary progression or, rarely, consider whether the balloon itself is the issue.

Beyond the second week, the balloon sits quietly for most people for the remainder of the roughly six months Mayo Clinic describes as its usual stay, before endoscopic removal. Occasional reflux and the sensation of fullness after modest meals tend to persist, because that fullness is the mechanism doing its job.

Anti-nausea and acid medicines: what they do and who decides

Most programs send people home with two kinds of prescription, and understanding their purpose makes the first week less mysterious. Decisions about whether to use them, for how long, and in what way rest entirely with the prescribing clinician; this section explains only how they work.

Antiemetics are medicines that dampen the vomiting reflex. Different classes act at different points along the pathway from stomach to brainstem. Some block serotonin receptors in the gut and brainstem, the same pathway triggered by chemotherapy and surgery. Others block dopamine receptors in the brain’s vomiting center. A third group act on histamine or acetylcholine signaling, which is why some cause drowsiness. Your team chooses based on your history, other medicines and any heart rhythm considerations, since certain classes can affect the heart’s electrical timing.

Acid suppressants, most often a proton pump inhibitor, reduce the amount of acid the stomach produces. The balloon rubs constantly against the stomach lining and raises pressure that pushes acid up toward the esophagus. Lowering acid protects the lining from ulceration and eases reflux. Mayo Clinic lists ulcers as a possible complication of the balloon, which is the reason acid protection is commonly continued for the months the device remains in place rather than just the first week.

Some teams add a short course of a medicine that relaxes the stomach muscle or reduces spasm for the early days of cramping. Others do not, judging that adaptation happens quickly enough without it.

Two practical points matter. First, timing relative to eating and lying down affects how well these medicines work, and your team’s instructions on that are worth following exactly. Second, if you cannot keep a prescribed medicine down because of vomiting, that is a reason to call rather than to double up or skip. Stopping, starting or changing any of these is a conversation with the prescriber, never a solo decision.

Eating and drinking in the first week: what helps the stomach settle

Almost every early symptom is either caused or worsened by how liquid arrives in the stomach. The organ that now hosts a balloon has perhaps a third of its usual free space, and a large gulp of water lands on a muscle that is already irritated. Small, frequent sips are the single most useful habit in week one, and the reasoning is mechanical rather than motivational.

Most programs begin with clear liquids on the day of placement and for a day or two afterward: water, diluted juice without pulp, broth, and oral rehydration drinks if advised. Sipping roughly every ten to fifteen minutes while awake usually delivers enough fluid without provoking a cramp. Room-temperature or warm liquids are better tolerated by many people than icy ones, which can trigger a stronger contraction, though this is individual.

Full liquids such as thin soups, smooth yogurt drinks and protein shakes typically follow once clear liquids stay down, and puréed or very soft foods come after that, often toward the end of the first week or into the second. The order and pace depend on your team’s protocol and how your stomach behaves, not on the calendar.

A few things reliably make matters worse. Carbonated drinks add gas to a stomach that already has too little room. Straws pull in extra air with every sip. Drinking and eating at the same time fills the limited space too quickly, which is why most teams ask people to separate the two by around half an hour once soft food begins. Lying flat soon after any intake lets acid and contents press toward the esophagus, so staying upright for a while afterward reduces reflux.

Protein matters even in the liquid phase, because the body will otherwise draw on muscle. Your dietitian will set targets suited to you. The NHS guidance on weight-loss procedures stresses that long-term success depends on the eating pattern built around the intervention, and that pattern starts in this awkward first week.

Acid reflux, bloating and belching: the quieter side effects

Nausea and cramps get the attention, but a cluster of less dramatic symptoms shapes daily comfort for longer. Understanding why each happens makes them easier to manage and easier to describe accurately to your team.

Acid reflux is the movement of stomach contents up into the esophagus, felt as burning behind the breastbone, a sour taste or a dry cough. The balloon raises pressure inside the stomach and can nudge the valve at the top open slightly. It is among the most persistent balloon side effects and can continue beyond the first week. Mayo Clinic lists ulcers as a possible complication of the device, and reflux that is worsening rather than steady is one of the things acid-suppressing medicine is intended to prevent from progressing. Eating small amounts, staying upright after intake and avoiding late meals reduce the number of episodes.

Bloating is the sensation of a stretched, tight abdomen. Its main sources in balloon patients are swallowed air, slower emptying of the stomach and the fermentation of new foods by gut bacteria. It is uncomfortable but not dangerous unless it comes with severe pain or a visibly distended, hard belly, which changes the picture entirely.

Belching is the body’s efficient answer to bloating, and it tends to be frequent in the first weeks. It is socially awkward and medically unremarkable. Excessive belching often signals excess swallowed air, so the same measures that reduce bloating help here.

Bad breath and a coated tongue sometimes appear, partly from reduced food intake and partly from reflux. Gentle oral hygiene and adequate fluids usually manage it. Hiccups can occur from irritation of the diaphragm above the balloon and usually pass.

Fatigue rounds out the list. Low calorie intake, disrupted sleep from nighttime reflux, and the general effort of adaptation combine to leave many people unusually tired for a week or two. Gentle walking, rather than pushing through, is generally what teams advise.

Dehydration: the risk that hides behind ordinary nausea

The most common way a normal first week becomes a medical problem is not the balloon itself but the fluid that fails to go in around it. Nausea suppresses thirst. Vomiting removes what was swallowed. A person doing their best to sip may still fall behind, and dehydration then worsens nausea, creating a loop that is hard to escape without help.

MedlinePlus describes the early signs of dehydration as thirst, dry mouth, passing less urine than usual, urine that is darker than normal, tiredness and dizziness, especially on standing. As it deepens, symptoms include confusion, a racing heart, sunken eyes, very dry skin and little or no urine. Mayo Clinic adds that older adults and people with chronic conditions are more vulnerable and may not feel thirsty until they are already significantly dry.

The practical measure most teams use is urine. Pale straw-colored urine several times a day suggests fluids are keeping pace. Dark, infrequent urine means they are not, whatever the tally of sips. A second measure is how you feel on standing: lightheadedness or a rushing heartbeat when you get up points to a low circulating volume.

Prevention rests on the sipping habit described earlier, spread across all waking hours, including a glass by the bed. Oral rehydration solutions, which contain balanced salts and sugar, replace what vomiting removes more effectively than water alone; your team can advise whether they are appropriate for you. Broth contributes both fluid and salt.

Dehydration is also the reason vomiting has a time limit in every set of discharge instructions. If you cannot keep liquids down for a sustained period, typically described as most of a day, the answer is not to wait it out. Clinics can give fluids and anti-nausea medicine by other routes and can check whether the balloon is sitting where it should. Calling early is the correct response, not an overreaction.

What people often get wrong about gastric balloon side effects

Much of the anxiety in the first week comes from beliefs that sound reasonable and are not quite true. Correcting them is part of feeling in control.

The first myth is that nausea means the balloon has moved or burst. Early nausea is the stomach’s normal response to a new object, as Mayo Clinic’s one-in-three figure reflects. A leaking or deflated balloon has its own signs, such as a sudden loss of the fullness sensation or blue-green urine in devices containing a marker dye, and is discussed in the complications section below. Ordinary queasiness is not evidence of either.

The second is that a rougher first week means better results. There is no established relationship between how sick someone feels early and how much weight they lose later. Adaptation speed is individual and says nothing about the months ahead.

The third is that pushing through vomiting is a sign of commitment. Repeated vomiting risks dehydration, tears in the lining of the esophagus and, rarely, displacement of the balloon. Teams would far rather adjust medicines than have someone endure a day of retching.

The fourth is that cramping means you should stop drinking. Sipping can trigger a contraction, but withholding fluid leads to dehydration, which worsens nausea. The fix is slower and smaller, not less.

The fifth is that the balloon alone does the work. The NHS frames all weight-loss interventions as tools within a broader program of eating and activity change, and Mayo Clinic describes the balloon as one part of a supervised plan. The first week’s dietary rules are the beginning of that program, not a hurdle before it.

The sixth is that reflux is trivial and can be ignored. Persistent or worsening reflux is one of the things the team monitors because of the risk of ulceration, so it belongs in your follow-up conversation rather than in the category of things you simply put up with.

Rare but serious complications your team watches for

Mayo Clinic describes serious side effects after balloon placement as rare, and it is worth holding onto that word while also knowing what the rare events look like. Neutral awareness is not fear; it is the reason discharge instructions include a phone number.

Balloon deflation is the most discussed. If the silicone develops a leak, the saline escapes and the balloon shrinks. Mayo Clinic notes that a deflated balloon could move through the digestive system and cause a blockage that may require surgery or another procedure to remove. Many balloons contain a dye that turns urine an unusual blue or green if the balloon leaks, which is why some teams ask people to watch urine color throughout the months the device is in place. A sudden return of appetite or loss of the constant fullness can be another clue.

Ulcers are sores in the stomach lining, and Mayo Clinic lists them among the possible complications. Constant contact and pressure from the balloon, combined with acid, can erode the lining. Signs include worsening or new upper abdominal pain, black or tarry stools, vomiting blood or material resembling coffee grounds, and unexplained lightheadedness. Acid-suppressing medicine is used partly to lower this risk.

Perforation, a hole in the stomach wall, is very rare but serious. Mayo Clinic notes it may require surgery to repair. It typically presents as sudden, severe, unrelenting abdominal pain, often with a rigid belly, fever and rapid pulse. This is an emergency, not a phone call.

Inflammation of the pancreas has been reported in some people, felt as severe pain that bores through to the back. Persistent vomiting that resists medicines, sometimes called balloon intolerance, is not dangerous in itself but can lead to dehydration and may prompt early removal, a decision your team would make with you.

None of these should be self-diagnosed. Their purpose here is to make the red-flag list that follows feel logical rather than arbitrary.

Questions to ask your care team before and after placement

The best time to ask about the first week is before it begins, and the second best is at the follow-up contact most programs schedule within days of placement. Bringing a written list makes a rushed conversation more useful. The questions below are starting points; your own situation will add others.

• What symptoms do you expect me to have in the first three days, and which ones would you want to hear about the same day?
• Which number do I call overnight or at the weekend, and what happens when I call it?
• How long do you expect me to need the anti-nausea medicine, and what should I do if I vomit shortly after taking it?
• Will I be on acid-suppressing medicine for the whole time the balloon is in place, and why?
• What is the exact order and pace of liquids, purées and soft foods for me, and what tells me I am ready to move to the next stage?
• How much fluid should I aim for each day, and how will I know I am falling behind?
• Does my balloon contain a marker dye, and if so what urine color should prompt a call?
• Which of my usual medicines, including over-the-counter pain relievers, need to change while the balloon is in, and who manages that?
• If I cannot tolerate the balloon, what does early removal involve and how is that decision made?
• What activity is reasonable in week one, and when can I return to work, driving and exercise?
• What does follow-up look like across the months the balloon stays in, and who is my point of contact for eating and lifestyle support?

Notice that several questions are about logistics rather than medicine. Knowing who answers the phone at two in the morning changes how the third night feels. Notice too that none of the answers should come from a leaflet or a forum; they belong to the team that placed your balloon and knows your history.

When to call your doctor: gastric balloon red flag symptoms

Ordinary first-week symptoms improve over days and never include fever, blood or unrelenting pain. The signs below fall outside that pattern. If any appears, call your care team the same day; if it is sudden and severe, use emergency services.

Call your team promptly if you have vomiting that prevents you keeping any fluids down for most of a day, or that continues beyond the few days Mayo Clinic describes as typical without improving. Call if you notice signs of dehydration described by MedlinePlus: very dark or scant urine, dizziness on standing, a racing heart, confusion or extreme tiredness. Call if abdominal pain is worsening rather than easing, has become constant rather than cyclical, or has spread across the whole belly. Call if you develop a fever, or if reflux becomes severe, keeps you from sleeping, or comes with difficulty swallowing.

Seek emergency care immediately for sudden, severe, unrelenting abdominal pain, especially with a rigid or hard belly, fever and a rapid pulse, since Mayo Clinic notes perforation as a rare complication that may need surgery. Do the same for vomiting blood or material that looks like coffee grounds, black or tarry stools, chest pain, shortness of breath, or fainting. Blue or green urine in a balloon that contains marker dye suggests the balloon has leaked; Mayo Clinic warns a deflated balloon can move and cause a blockage, so this needs urgent contact with your team even if you feel well.

A short rule of thumb: symptoms that were getting better and then abruptly get worse, or that arrive brand new after a period of feeling settled, are the ones to report without delay. No one on a bariatric team regards an early call as a nuisance. The decision about what happens next, from adjusting medicines to arranging an endoscopy or removing the balloon, rests with them, and the sooner they have the information, the more options they have.

Frequently asked questions

How long does gastric balloon nausea last for most people?

Mayo Clinic states that nausea and pain after intragastric balloon placement usually last only a few days. Most teams describe a peak in the first 48 to 72 hours followed by steady improvement, with the majority of people managing liquids and soft foods by the end of the first week. A smaller group needs closer to two weeks. Nausea persisting beyond that should be reviewed by your care team rather than waited out.

Are stomach cramps after a gastric balloon normal?

Yes, cyclical cramping high in the abdomen is expected in the first week. The stomach’s muscular wall contracts in waves and meets a balloon it cannot move along, producing a gripping ache that builds, holds and releases. Cramps that are constant, severe, spreading across the whole abdomen, or accompanied by fever, a rigid belly or persistent vomiting are different and should prompt a same-day call to your team.

What does a typical gastric balloon recovery timeline look like?

The first three days usually bring peak nausea, cramping and fatigue while you sip clear liquids. Days four to seven typically show flattening symptoms and a move toward full liquids or purées if your team allows. By the second week most people tolerate soft foods, with some lingering reflux or bloating. Mayo Clinic describes the balloon as generally staying in place for about six months before endoscopic removal. Individual timelines vary and your team sets the pace.

What are the gastric balloon red flag symptoms I should never ignore?

Call your team the same day for vomiting that stops you keeping fluids down, signs of dehydration such as dark scant urine or dizziness, worsening or constant abdominal pain, or fever. Seek emergency care for sudden severe unrelenting pain with a rigid belly, vomiting blood or coffee-ground material, black stools, chest pain or fainting. Blue or green urine may indicate balloon leakage and needs urgent contact with your team.

Why does the balloon cause acid reflux?

The balloon raises pressure inside the stomach and can nudge open the valve between the stomach and esophagus, letting acid travel upward. It also slows emptying, so contents sit longer. Reflux can outlast the first week. Because Mayo Clinic lists ulcers as a possible complication, acid-suppressing medicine is often continued for the months the balloon is in place. Small meals, staying upright after eating and avoiding late intake reduce episodes.

Does feeling very sick in the first week mean the balloon has moved or leaked?

Usually not. Early nausea is the stomach’s expected response to a new object, which Mayo Clinic’s one-in-three figure reflects. A leaking balloon has different signs: a sudden loss of the constant fullness, a return of appetite, or blue or green urine in devices containing marker dye. Mayo Clinic notes a deflated balloon can move and cause a blockage, so those specific signs need urgent contact with your team even without nausea.

Can I take my usual painkillers for the cramps?

That decision belongs to your prescribing clinician. Some common over-the-counter pain relievers irritate the stomach lining, which matters when a balloon is already pressing against it and ulcers are a recognized risk. Your team will tell you which medicines are acceptable while the balloon is in place and which to avoid, and may suggest alternatives. Never start, stop or change a medicine during this period without checking with them first.

How do I know if I am getting dehydrated?

MedlinePlus lists thirst, dry mouth, passing less urine than usual, darker urine, tiredness and dizziness as early signs, with confusion, a racing heart and very little urine as it deepens. The simplest home check is urine color: pale straw several times a day suggests you are keeping up, while dark and infrequent means you are not. If you cannot keep fluids down for most of a day, call your team.

Should I stop sipping fluids if drinking triggers cramps?

No. Sipping can provoke a contraction because the stomach responds to any arrival, but withholding fluid leads to dehydration, which worsens nausea and creates a difficult loop. The adjustment is smaller and slower, not less: a few sips every ten to fifteen minutes, room temperature rather than icy, without straws or carbonation. If even small sips are not staying down, that is the point to contact your team.

What happens if I simply cannot tolerate the balloon?

A minority of people have persistent vomiting or discomfort that does not settle with medicines and time, sometimes called balloon intolerance. It is not dangerous in itself but risks dehydration, so teams take it seriously. The usual response is to review medicines and diet first and, if symptoms remain unmanageable, to discuss early removal by endoscopy. That decision is made together with your treating team based on your specific situation.
