Endoscopy is a medical procedure used to examine the inside of the digestive tract, including the esophagus, stomach, and upper part of the small intestine. Doctors commonly recommend endoscopy to evaluate symptoms such as persistent stomach pain, acid reflux, difficulty swallowing, vomiting, or unexplained bleeding. It is also useful for diagnosing conditions like gastritis, ulcers, infections, and early-stage cancers.

The procedure is performed using a thin, flexible tube called an endoscope, which has a camera and light at its tip. The endoscope is gently passed through the mouth and into the digestive tract, allowing the doctor to view clear images on a monitor. Endoscopy is usually done under local anesthesia or light sedation to ensure patient comfort.

Endoscopy is a safe and minimally invasive procedure. In addition to diagnosis, it can also be used for treatment, such as stopping bleeding or taking tissue samples (biopsy). It plays an important role in early detection and effective management of digestive diseases.
