Definition
A gastroscope is a long, thin, flexible tube with a camera and light attached, used to examine the inside of the esophagus, stomach, and duodenum (the first part of the small intestine). 🩺 It's inserted through the mouth or nose to visualize the digestive tract. Think of it as a tiny submarine exploring your insides. Gastroscopes help doctors diagnose conditions like ulcers, inflammation, and tumors. It's a non-surgical way to get a close-up view of your digestive health. While it sounds scary, it's a valuable diagnostic tool.
