Colonoscopy is an important diagnostic and therapeutic procedure used to examine the inner lining of the large intestine, including the colon and rectum. It is performed using a thin, flexible tube with a high-resolution camera that allows the doctor to identify abnormalities and investigate various gastrointestinal symptoms. Dr. Sandeep Jha provides comprehensive evaluation and management for patients who may require colonoscopy for symptoms such as persistent abdominal pain, unexplained weight loss, blood in the stool, prolonged changes in bowel habits, chronic diarrhea, constipation, anemia, or suspected intestinal disease. Colonoscopy may also be recommended for screening and early detection of colorectal cancer, particularly in individuals with appropriate risk factors or family history. During the procedure, the colonoscope is gently introduced through the rectum and advanced through the large intestine. The doctor carefully examines the intestinal lining for conditions such as polyps, inflammation, ulcers, bleeding, diverticular disease, and other abnormalities. If a polyp or suspicious area is identified, it may be removed or a biopsy may be taken for laboratory examination. Proper bowel preparation before colonoscopy is essential because a clean colon allows better visualization and improves the accuracy of the examination. Patients are usually given specific dietary and bowel-cleansing instructions before the procedure. Sedation may be provided to improve comfort during the examination. Colonoscopy can play an important role in both diagnosis and prevention. Detecting and removing certain precancerous polyps can help reduce the future risk of colorectal cancer. The procedure is generally safe when performed by an experienced specialist, although patients should be informed about potential risks and follow appropriate aftercare instructions. If you have persistent digestive symptoms or have been advised to undergo colonoscopy, consult an experienced gastrointestinal surgeon for proper evaluation and personalized treatment.
