Endoscopy

Endoscopy is a diagnostic medical procedure used to visually examine the upper part of the digestive system, including the esophagus, stomach, and the beginning of the small intestine (duodenum).

A thin, flexible tube with a camera called an endoscope is gently inserted through the mouth. This allows doctors to directly view the internal lining of the upper gastrointestinal tract and identify abnormalities such as ulcers, inflammation, bleeding, infections, or early signs of cancer.

Endoscopy is a highly accurate and commonly used procedure in gastroenterology for diagnosing digestive problems.

Benefits of the Test

• Detects stomach ulcers and gastritis
• Identifies acid reflux and GERD complications
• Helps diagnose gastrointestinal bleeding
• Detects early-stage stomach or esophageal cancer
• Allows biopsy collection for further analysis
• Provides direct visualization of digestive tract health

Why Doctors Recommend This Test

Doctors recommend endoscopy when patients experience persistent symptoms such as chronic acidity, difficulty swallowing, vomiting blood, unexplained weight loss, or upper abdominal pain. It is also advised when initial treatments do not improve symptoms or when serious gastrointestinal conditions are suspected.

Endoscopy helps in early diagnosis and timely treatment, reducing the risk of complications.

• Avoid food and drinks before the test
• Inform doctor about allergies or medications
• Remove dentures or loose dental appliances
