What to Expect During and After a Gastroscopy

A gastroscopy, also known as an upper endoscopy, is a medical procedure that allows doctors to examine the lining of your upper digestive tract, including the esophagus, stomach, and the beginning of the small intestine (duodenum). If your doctor has recommended a gastroscopy, you might feel nervous or unsure about the procedure. Dr. Vikram Jayanty and Dr. Julien Fahed in Houston, TX, can explain a gastroscopy and what you can expect from the procedure.

Knowing What To Expect From a Gastroscopy

Your gastroenterologist in Houston, TX, may recommend a gastroscopy for certain symptoms, including:

• Persistent abdominal pain
• Heartburn
• Acid reflux
• Difficulty swallowing
• Unexplained weight loss
• Nausea or vomiting
• Anemia due to unexplained blood loss

It can also be used to diagnose conditions such as ulcers, gastritis, and celiac disease and to check for signs of cancer. Additionally, doctors may perform therapeutic interventions during a gastroscopy, such as removing polyps, treating bleeding, or stretching a narrowed section of the esophagus.

Before the procedure, you’ll need to fast for 6-8 hours from food and all drinks. It’s important to arrange a ride home after the procedure to ensure you’re safe and cared for.

Most patients receive mild sedation to help them relax and feel comfortable. You may also receive a local anesthetic spray to numb your throat, reducing the urge to gag when the endoscope is inserted. Once you’re comfortable, the doctor will gently guide the endoscope (a thin, flexible tube with a light and camera) through your mouth, throat, and stomach. The endoscope transmits images to a monitor, allowing the doctor to examine the upper digestive tract. The gastroscopy typically takes about 15-30 minutes, depending on whether additional treatments, like biopsy or polyp removal, are performed.

After the procedure, you’ll be monitored for 30 minutes to an hour as the sedation wears off. Most patients feel groggy afterward, so plan to take it easy for the rest of the day. You might experience a mild sore throat, bloating or gas, and drowsiness. Avoid driving, operating machinery, or drinking alcohol for at least 24 hours post-procedure due to the lingering effects of sedation. You can usually resume regular eating and activities the following day, unless otherwise instructed by your doctor.
