Inside the Colonoscopy: What Doctors in Bengaluru Gastro See – Polyps, Cancer Signs & Prep Explained

Have you ever wondered exactly what happens during a colonoscopy and what your doctor sees inside your colon? In this video, we take you into the procedure step-by-step with clear, no-nonsense explanations for patients in India (and everywhere) — whether you’re in Bengaluru, Mumbai, Delhi or any city.

What you’ll learn:

What a colonoscopy is, how it works, what the camera and scope actually do (insufflation, maneuvering)

The common findings: benign-looking but potentially risky polyps (adenomatous, serrated), diverticula, inflammation (including ulcerative colitis / Crohn’s changes), bleeding points, strictures

When doctors remove a polyp immediately on-table vs when they take a biopsy and wait for histology

Why the bowel prep matters so much: a clean colon = much better visibility, higher detection rate (especially relevant in India where prep quality varies)

What sedation is like, whether it hurts, how long recovery takes, and what to expect after the procedure

Who should undergo screening in India: when (age), how often, what family history or symptoms matter

Why this matters for you in India:
Colorectal cancer is one of the most preventable cancers — and yet polyps can grow quietly for years before symptoms appear. In India too, earlier detection via colonoscopy can save lives. By seeing real-life examples of what doctors actually look for — and how they remove or biopsy findings — you’ll be empowered to ask the right questions, get the right prep, and understand follow-up with confidence.

Let’s talk prep & sedation:
Prep isn’t just “drink the solution the night before” — we’ll show what good prep means (low-fibre diet in the days ahead, avoiding raw veg and high-fibres, clear liquids, following your clinic’s instructions) and how poor prep reduces visibility. Good sedation means most Indian patients feel minimal discomfort — a few cramps or pressure maybe, but you’re asleep/comfortable and back home in hours. We’ll describe typical times (20-45 minutes for the procedure itself, more for prep/recovery) and what your recovery at home should look like.

What doctors see, and why it’s important:
We cover examples of normal colon mucosa, how different polyps look (flat vs raised; serrated vs adenomatous), what ulcers or IBD changes might look like, how bleeding sources or diverticula show up — and how subtle changes can hint at early cancer. We’ll also walk through how on-the-spot removal (polypectomy) works, and when doctors choose biopsy + watchful follow-up instead.

Screening: when & for whom:
In many guidelines screening starts at age 45 for average risk (some Indian clinics may even start earlier depending on family history). If you have a first-degree relative with colorectal cancer, prior polyps, unexplained bleeding, weight-loss or bowel-habit change — speak to your doctor about earlier screening. Frequency depends on what’s found: no polyps → longer interval; polyps/IBD/history → shorter.

Take-aways:

A colonoscopy is not just diagnostic — it’s preventive: removing polyps interrupts the pathway to cancer.

Poor prep = lower detection = reduced benefit.

Sedation is safe and discomfort is minimal.

Talk to your gastroenterologist in India about your risk, local recommended interval, sedation and prep specifics.

Don’t delay: screening saves lives.
