Peptic Ulcer

Quick answer

Peptic ulcer is a sore that forms in the lining of the stomach or the first part of the small intestine, usually linked to Helicobacter pylori infection or long-term use of anti-inflammatory pain medicines. At Acibadem in Turkey, evaluation focuses on confirming the ulcer and its cause with gastroenterology assessment and tests such as endoscopy, and treatment typically includes acid-suppressing…

Overview

A peptic ulcer is a sore that develops in the lining of the stomach or the first part of the small intestine, called the duodenum. Ulcers in the stomach are known as gastric ulcers, while ulcers in the duodenum are called duodenal ulcers. Both are related to irritation and damage of the protective lining that normally shields the digestive tract from stomach acid.

Peptic ulcers are a common gastrointestinal condition and can occur at any age, although they are more frequent in adults. Many ulcers can be treated effectively when the underlying cause is identified. Without appropriate medical care, some ulcers may lead to complications such as bleeding, narrowing of the digestive tract, or, rarely, a hole in the stomach or intestinal wall.

Symptoms

The symptoms of a peptic ulcer can vary from mild discomfort to more serious signs. Some people have no symptoms, especially in the early stages. When symptoms occur, they may come and go over days or weeks.

  • Burning, gnawing, or aching pain in the upper abdomen
  • Discomfort that may be worse when the stomach is empty or at night
  • Feeling full quickly during meals
  • Bloating or belching
  • Nausea or occasional vomiting
  • Indigestion or heartburn-like discomfort
  • Reduced appetite or unintended weight loss in some cases

More serious symptoms can suggest bleeding or another complication. These may include black or tar-like stools, vomiting blood or material that looks like coffee grounds, sudden severe abdominal pain, dizziness, fainting, or unusual weakness. These symptoms require urgent medical attention.

Causes and Risk Factors

Peptic ulcers develop when the balance between stomach acid and the protective lining of the digestive tract is disrupted. The most common cause is infection with a bacterium called Helicobacter pylori. This infection can weaken the stomach’s natural defenses and increase inflammation, making ulcers more likely to form.

Another common cause is regular use of certain pain-relieving or anti-inflammatory medicines, which can irritate the stomach lining and reduce its ability to protect itself. The risk may be higher when these medicines are taken frequently, for a long time, or in combination with other factors.

Other factors may increase the risk of developing or worsening ulcers, including:

  • Smoking
  • Heavy alcohol use
  • Previous history of peptic ulcer disease
  • Older age
  • Serious illness or physical stress in hospitalized patients
  • Family history of ulcers in some cases

Spicy foods and daily stress do not usually cause peptic ulcers on their own, but they may worsen symptoms in some people. Dietary triggers can vary from person to person.

Diagnosis

Diagnosis begins with a medical history and physical examination. A gastroenterology specialist may ask about the location and timing of pain, digestive symptoms, medication use, smoking, alcohol intake, and any signs of bleeding or weight loss.

Tests may be recommended to look for Helicobacter pylori infection. These may include breath, stool, or blood tests, depending on the patient’s situation and local medical practice. If symptoms are persistent, severe, or associated with warning signs, an upper gastrointestinal endoscopy may be performed. During this procedure, a thin flexible tube with a camera is used to examine the esophagus, stomach, and duodenum. Small tissue samples may be taken for laboratory evaluation when needed.

In some cases, imaging tests may be used to assess complications or to evaluate other possible causes of abdominal pain. The choice of tests depends on the patient’s age, symptoms, medical history, and examination findings.

Treatment Options

Treatment for peptic ulcer disease depends on the cause, ulcer location, severity of symptoms, and whether complications are present. If Helicobacter pylori infection is found, treatment usually includes a combination of medications to clear the infection and reduce stomach acid. If the ulcer is related to pain-relieving or anti-inflammatory medicines, the doctor may recommend stopping, changing, or adjusting them when medically safe.

Medicines that reduce stomach acid or protect the lining of the stomach may help the ulcer heal and relieve symptoms. The specific treatment plan should be determined by a healthcare professional, especially for patients who take regular medications for other conditions.

Lifestyle changes may also support recovery and reduce irritation. These may include avoiding smoking, limiting alcohol, and discussing any stomach-irritating medicines with a doctor. Some people benefit from identifying foods or drinks that worsen their symptoms, but there is no single ulcer diet that is suitable for everyone.

Most peptic ulcers improve with appropriate medical treatment, but follow-up may be needed to confirm healing, especially for gastric ulcers or ulcers with concerning features. If bleeding, obstruction, or perforation occurs, hospital care and additional procedures may be required.

When to See a Doctor

A doctor should be consulted if upper abdominal pain, indigestion, nausea, or bloating is persistent, recurrent, or affecting daily life. Medical advice is also important for people who regularly use pain-relieving or anti-inflammatory medicines and develop stomach discomfort.

Seek urgent medical care if there is vomiting of blood, black or tar-like stools, sudden severe abdominal pain, fainting, chest discomfort, difficulty breathing, or signs of severe weakness. These may indicate a serious complication and should not be ignored.

International patients with ongoing digestive symptoms can benefit from evaluation by a gastroenterology team. Early assessment helps identify the cause, guide appropriate treatment, and reduce the risk of complications.
