When it comes to getting to the root of digestive issues, sometimes symptoms only tell part of the story. That’s where diagnostic tools like upper endoscopy come in—offering a closer look at what’s happening inside. At the office of Stephen K. Buto, MD in Honolulu, upper endoscopy is a trusted procedure that helps uncover the causes behind a range of gastrointestinal concerns.

What Is an Upper Endoscopy?

An upper endoscopy, also called an esophagogastroduodenoscopy (EGD), is a minimally invasive procedure that allows a gastroenterologist to view the lining of the esophagus, stomach, and the first part of the small intestine (duodenum). Using a thin, flexible tube equipped with a light and camera, Dr. Buto can identify inflammation, ulcers, growths, and other abnormalities that might be contributing to your symptoms.

The procedure typically takes less than 30 minutes and is done with mild sedation, making it both effective and relatively easy to recover from.

Persistent Heartburn or Acid Reflux

If you experience ongoing heartburn or acid reflux that doesn’t improve with over-the-counter treatments, an upper endoscopy may be recommended. The goal is to check for complications of GERD (gastroesophageal reflux disease), such as esophagitis or Barrett’s esophagus, a condition that can increase the risk of esophageal cancer if left untreated.

Difficulty Swallowing

Feeling like food gets “stuck” in your throat or chest could signal a problem in the esophagus. An upper endoscopy helps identify causes like strictures (narrowing), inflammation, or even motility disorders. Pinpointing the reason for swallowing issues is essential in preventing further complications and discomfort.

Unexplained Stomach Pain or Nausea

When stomach pain, bloating, nausea, or vomiting becomes chronic, and other tests haven’t provided clear answers, an upper endoscopy may be the next step. It allows your doctor to look for ulcers, gastritis, or other structural issues that might be contributing to ongoing digestive discomfort.

Anemia or Bleeding

Unexplained anemia or signs of gastrointestinal bleeding—such as black, tarry stools or vomiting blood—warrant further investigation. An upper endoscopy can detect the source of bleeding, such as a peptic ulcer or a bleeding lesion, and in some cases, treatment can be delivered during the same procedure.

Monitoring Known Conditions

For those with a history of ulcers, Barrett’s esophagus, or previous gastrointestinal surgery, periodic endoscopy may be necessary to monitor for changes or recurrence. It’s a proactive way to stay ahead of potential complications.
