When Do You Need an Upper Endoscopy? Brooklyn GI Doctor Explains

An upper endoscopy, also called an EGD, is a test that allows a gastroenterologist to examine the esophagus, stomach, and the first part of the small intestine. It is commonly used to evaluate symptoms such as acid reflux, upper abdominal pain, nausea, vomiting, trouble swallowing, black stool, anemia, and suspected ulcers or gastritis.

Many patients try medications first for symptoms like heartburn, reflux, or stomach burning. Sometimes that is enough. But when symptoms continue, worsen, or come with warning signs, an upper endoscopy may be needed to find the cause.

During an upper endoscopy, a thin flexible camera is passed through the mouth while the patient is sedated. The doctor can directly see the lining of the esophagus and stomach. This can help diagnose conditions such as esophagitis, gastritis, ulcers, hiatal hernia, narrowing of the esophagus, Barrett’s esophagus, bleeding, masses, or infection. Biopsies may be taken to check for inflammation, H. pylori, celiac disease, Barrett’s esophagus, or other conditions.

You may need an upper endoscopy if you have acid reflux that is not improving with medication, frequent heartburn, burning in the upper abdomen, persistent nausea, vomiting, difficulty swallowing, pain with swallowing, unexplained weight loss, anemia, black stool, vomiting blood, or ongoing stomach pain. Patients with long-standing GERD or risk factors for Barrett’s esophagus may also need evaluation.

An upper endoscopy is also useful when gastritis or ulcers are suspected. Gastritis is inflammation of the stomach lining and may cause burning pain, nausea, bloating, early fullness, or discomfort after eating. Causes may include H. pylori, NSAID medications such as ibuprofen or naproxen, alcohol, stress-related irritation, bile reflux, or other medical conditions. Endoscopy helps confirm the diagnosis and allows biopsy if needed.

Black stool, also called melena, is an important warning sign because it may suggest bleeding in the upper GI tract. This can come from ulcers, gastritis, esophageal irritation, or other bleeding sources. If you notice black, tarry stool or vomiting blood, you should seek urgent medical evaluation.

Patients often ask if an upper endoscopy is painful. The procedure is generally performed with sedation, and most patients do not feel pain during the test. The procedure itself is usually quick, and patients go home the same day with instructions after recovery from sedation.
