Colonoscopy in Yelahanka, Bangalore — Early Cancer Detection

What is a Colonoscopy?

A colonoscopy is a detailed examination of the entire large intestine (colon) and rectum using a long, flexible camera called a colonoscope. It is the gold standard for detecting colon cancer in its early stages — when it is most treatable — as well as diagnosing conditions like inflammatory bowel disease, polyps, unexplained bleeding and chronic diarrhoea.

At Dhaara Speciality Hospital, colonoscopies are performed by Dr. Srinivas Bojanapu, an experienced Surgical Gastroenterologist. We use state-of-the-art high-definition colonoscopes in a dedicated, sterile endoscopy suite.

Why is Colonoscopy Important?

Colorectal cancer is one of the most common cancers in India and is rapidly increasing due to changing dietary habits. The good news is that it is largely preventable with regular colonoscopy screening. Colonoscopy can detect pre-cancerous polyps and remove them before they ever become cancer.

In India, doctors recommend colonoscopy screening starting at age 45 for average-risk individuals, and earlier if you have a family history of colon cancer or symptoms.

When is Colonoscopy Recommended?

• Blood in stools (rectal bleeding) or dark, tarry stools
• Chronic diarrhoea or constipation lasting more than 3 weeks
• Unexplained abdominal cramps or bloating
• Unexplained iron-deficiency anaemia
• Significant unintentional weight loss
• Family history of colorectal cancer or polyps
• Personal history of inflammatory bowel disease (Crohn's, ulcerative colitis)
• Routine colorectal cancer screening (age 45+)
• Follow-up after previous polyp removal

How to Prepare for a Colonoscopy?

Proper bowel preparation is essential for a clear, accurate examination. Our team will give you detailed written instructions, which typically include:

1. 2 days before: Shift to a low-fibre diet (no vegetables, fruits or seeds)
2. 1 day before: Clear liquid diet only — water, coconut water, clear soups, fruit juices without pulp
3. Bowel prep solution: A laxative preparation to completely cleanse the colon (our team will prescribe this)
4. Day of procedure: Nothing by mouth for at least 4 hours before the procedure
5. Medications: Continue most medications with a small sip of water; specific guidance will be given for blood thinners and diabetes medications

Therapeutic Uses of Colonoscopy

Colonoscopy at Dhaara Hospital is not just for diagnosis. Our expert team performs several treatments through the colonoscope:

• Polypectomy — removal of polyps to prevent cancer
• Haemostasis — stopping active colonic bleeding
• Biopsy — tissue sampling for accurate diagnosis
• Stricture dilatation — widening narrowed segments of the colon
• Foreign body removal — retrieval of objects from the colon
