Essential studies for early detection of digestive problems: ulcers, reflux, polyps, and early colorectal cancer screening.

Studies we perform
🔬 Upper Endoscopy (gastroscopy) — Examination of esophagus, stomach, and first portion of small intestine using a thin flexible camera. Useful to detect: reflux, gastritis, hiatal hernia, ulcer, H. pylori infection, polyps, bleeding, and early tumors.
🧬 Colonoscopy — Complete examination of the large intestine (colon) with flexible camera. Allows biopsies and polyp removal in the same procedure. Detects: polyps, colorectal cancer, colitis, diverticula, internal hemorrhoids, causes of bleeding or bowel habit changes.
