Gastroscopy, also known as esophagogastroduodenoscopy (EGD), involves inserting a flexible tube with a camera through your mouth into your esophagus, stomach, and duodenum. ๐ฎ It allows doctors to visualize these organs directly to detect ulcers, inflammation, or tumors. Itโs like a scenic route through your upper digestive tract! It's more precise than an X-ray. It can help identify the cause of heartburn or abdominal pain.
