When Do You Need a Gastroscopy? Conditions a Gastroenterologist Can Diagnose

At the practice of Dr. Vikram Jayanty and Dr. Julien Fahed in Houston, TX, patients receive expert care for a wide range of gastrointestinal conditions. One of the most effective tools for diagnosing upper digestive issues is a procedure called gastroscopy, also known as an upper endoscopy. This minimally invasive exam uses a thin, flexible tube with a camera to evaluate the esophagus, stomach, and the first part of the small intestine. If you’re experiencing persistent digestive symptoms, a gastroscopy may be the key to identifying the root cause.

Reasons a Gastroenterologist May Recommend Gastroscopy

Gastroscopy is typically recommended when symptoms suggest an issue with the upper gastrointestinal tract that requires further examination. Recurring heartburn or acid reflux that will not subside with treatment might be a sign of gastroesophageal reflux disease (GERD), esophagitis, or Barrett's esophagus. Persistent stomach pain without an obvious cause might result in a gastroscopy to rule out ulcers or inflammation. Difficulty swallowing or the sensation of food sticking may be indicative of structural problems or esophageal strictures. Chronic vomiting or nausea, especially when accompanied by weight loss or dehydration, should also be investigated.

Conditions Diagnosed Through Gastroscopy

Gastroscopy provides a magnified view of the upper GI tract, enabling the diagnosis of peptic ulcers, gastritis, and esophagitis. It will detect changes in the lining of the esophagus caused by prolonged acid reflux, such as those found in Barrett's esophagus, or identify hiatal hernias that produce symptomatic reflux. Gastroscopy also diagnoses celiac disease, which is an autoimmune disease and can cause destruction in the small intestine due to gluten. Narrowing of the esophagus, strictures, or rings may explain difficulty in swallowing. Gastroscopy is used in a few cases to diagnose tumors or abnormal growths and to obtain tissue biopsy samples. It is also a method for identifying the source of gastrointestinal bleeding and, if accessible, treating it in the same sitting.

What to Expect During the Procedure

Gastroscopy is typically performed as an outpatient procedure, lasting approximately 15 to 30 minutes. You'll need to fast before the exam, and a sedative is typically given to help you stay relaxed. A local anesthetic may also be sprayed into your throat to minimize discomfort. During the procedure, the gastroenterologist gently passes a thin, flexible endoscope through your mouth and down into your upper digestive tract to capture detailed images of the area. If necessary, small tissue samples may be collected, or treatment may be provided on the spot. After the procedure, you'll rest while the sedative wears off and will need someone to drive you home. Most patients can resume normal activities the following day.
