Introduction

Two of the most frequently asked questions at Dr Gastro’s clinic in Ahmedabad are: “Doctor, do I need an endoscopy or a colonoscopy?” and “What exactly happens during these procedures?”

Both are diagnostic tools used by gastroenterologists to examine the digestive tract from the inside. Both involve a flexible camera. But they look at entirely different parts of your digestive system — and they are recommended for very different symptoms and conditions.

If your doctor has recommended an endoscopy in Ahmedabad or a colonoscopy — or if you have symptoms that might require one — this guide will tell you everything you need to know: the differences, when each is recommended, what the procedure involves, and what to expect at Dr Gastro’s clinic at Shaleen Multi Speciality Hospital, Sola, Ahmedabad.

What Is an Endoscopy?

An endoscopy (also called upper GI endoscopy or gastroscopy) is a procedure that examines the upper digestive tract — the oesophagus (food pipe), stomach, and the first part of the small intestine (duodenum).

A thin, flexible tube called an endoscope — with a high-definition camera and light at its tip — is passed gently through the mouth, down the throat, and into the stomach. The camera transmits live, magnified images to a monitor, allowing Dr Hamik Chandra Patel to examine the lining of your upper digestive tract in detail.

What Can an Upper Endoscopy Diagnose?

• Acid reflux (GERD) — oesophageal inflammation, strictures
• Gastric ulcers — stomach or duodenal ulcers
• Helicobacter pylori infection — the bacterium responsible for most peptic ulcers
• Oesophagitis — inflammation of the oesophagus
• Barrett’s Oesophagus — a precancerous change in the oesophageal lining
• Hiatal hernia — stomach pushing through the diaphragm
• Unexplained anaemia — bleeding from the upper GI tract
• Coeliac disease — biopsy samples from the duodenum for diagnosis
• Stomach cancer — early detection is the key to survival
• Swallowing difficulty (dysphagia) — identifying structural causes

What Can an Endoscopy Treat?

Beyond diagnosis, an endoscopy is also therapeutic:

• Biopsy collection for laboratory analysis
• Polyp removal from the stomach
• Bleeding control (endoscopic haemostasis)
• Removal of swallowed foreign bodies
• Dilatation of narrowed areas (strictures)
• ERCP — examination and treatment of bile duct and pancreatic conditions

What Is a Colonoscopy?

A colonoscopy examines the lower digestive tract — the entire large intestine (colon) and the terminal portion of the small intestine (ileum).

A longer, flexible scope is passed through the rectum and guided through the entire colon. This procedure requires bowel preparation the day before to ensure the colon is clean and clearly visible.

What Can a Colonoscopy Diagnose?

• Colorectal cancer — the most important reason for colonoscopy
• Polyps — precancerous growths on the colon lining (removed during the procedure)
• Inflammatory bowel disease (IBD) — Crohn’s disease and ulcerative colitis
• Diverticular disease — small pouches in the colon wall
• Unexplained rectal bleeding — identifying the source
• Chronic diarrhoea or constipation — investigating structural causes
• Iron deficiency anaemia — unexplained blood loss from the colon
• Post-cancer surveillance — monitoring after previous colorectal cancer treatment

What Can a Colonoscopy Treat?

• Polypectomy — removal of colon polyps (preventing cancer before it starts)
• Bleeding control — endoscopic treatment of bleeding points
• Biopsy — tissue samples for IBD diagnosis and cancer detection

Endoscopy vs Colonoscopy: Key Differences

Feature	Endoscopy (Upper GI)	Colonoscopy (Lower GI)
Area examined	Oesophagus, stomach, duodenum	Entire colon, rectum, terminal ileum
Entry point	Mouth	Rectum
Preparation required	Fasting for 6–8 hours	Bowel prep (laxatives) the day before
Procedure duration	10–20 minutes	30–60 minutes
Sedation	Light sedation or throat spray	Deeper sedation recommended
Primary use	Upper GI symptoms (acid, pain, vomiting)	Lower GI symptoms (bleeding, altered bowel habit)
Cancer screening	Stomach/oesophageal cancer	Colorectal cancer

When Does Dr. Hamik Recommend an Endoscopy in Ahmedabad?

Dr. Hamik Chandra Patel recommends upper endoscopy when patients present with:

• Persistent upper abdominal pain — especially pain that does not respond to antacids
• Chronic acidity or GERD — when symptoms persist despite medication or when Barrett’s Oesophagus is suspected
• Difficulty swallowing (dysphagia) — food sticking in the throat or chest
• Unexplained nausea or vomiting — particularly in older patients
• Unexplained weight loss — a red flag symptom requiring investigation
• Vomiting blood (haematemesis) — an emergency requiring immediate endoscopy
• Black, tarry stools (melaena) — indicating upper GI bleeding
• Anaemia — when a bleeding source in the upper GI tract is suspected
• Positive H. pylori test — to confirm and assess associated damage
• Family history of stomach cancer — surveillance in high-risk individuals
• Suspected coeliac disease — biopsy from the duodenum

When Does Dr Hamik Recommend a Colonoscopy?

Colonoscopy is recommended for:

• Rectal bleeding or blood in stools — never ignore this symptom
• Unexplained change in bowel habits — new constipation, diarrhoea, or alternating pattern
• Persistent lower abdominal cramps or bloating
• Iron deficiency anaemia — when colonoscopy is needed to rule out colorectal cancer
• Colorectal cancer screening — recommended from age 45–50, or earlier with family history
• Previous colorectal polyps or cancer — surveillance colonoscopy
• Suspected inflammatory bowel disease — Crohn’s disease or ulcerative colitis
• Abnormal CT scan findings in the colon requiring direct visualisation
• Unexplained significant weight loss combined with bowel symptoms

What to Expect During an Endoscopy at Dr Gastro’s Clinic, Ahmedabad

Before the Procedure

• Fast for 6–8 hours before your endoscopy (no food or water)
• Inform Dr. Hamik of any medications, especially blood thinners
• Bring a companion who can accompany you home if sedation is used
• Routine blood tests may be requested beforehand

During the Procedure

• You will lie on your left side on a procedure bed
• A mouthguard is placed to protect your teeth and the scope
• A throat spray or light sedation is administered for comfort
• The endoscope is gently passed through your mouth — you may feel mild pressure, but should not feel pain
• The entire procedure takes 10–20 minutes
• If biopsies are taken or polyps removed, you will not feel this

After the Procedure

• You will rest in recovery for 30–60 minutes
• If sedated, you cannot drive yourself home
• Mild bloating, belching, or a sore throat for a few hours is normal
• Biopsy results are typically available within 5–7 days
• Dr. Hamik discusses findings immediately after the procedure

What to Expect During a Colonoscopy at Dr Gastro’s Clinic, Ahmedabad

Bowel Preparation — The Day Before

The most important part of colonoscopy preparation is ensuring your colon is completely clean. Dr Hamik’s team will provide:

• A specific bowel preparation laxative to take the evening and morning before
• Clear dietary instructions (clear liquids only the day before)
• Timing instructions for medication use

A clean bowel is critical — inadequate preparation leads to a repeat procedure.

During the Procedure

• Performed under sedation for your comfort
• Duration is typically 30–60 minutes
• You may feel mild cramping as the scope moves through the colon’s curves
• Any polyps found are removed during the same procedure
• Biopsies are taken from any suspicious areas

After the Procedure

• Recovery takes 1–2 hours post-sedation
• Mild bloating or gas for a few hours is normal
• You cannot drive on the day of the procedure
• Results discussed immediately; biopsy reports in 5–7 days
• A soft diet is recommended for the remainder of the day

Can Both Be Done on the Same Day?

Yes — in selected cases, Dr Hamik Chandra Patel at Shaleen Hospital can perform both upper endoscopy and colonoscopy in a single session. This is called bidirectional endoscopy and avoids the need for two separate preparations and appointments. This is particularly convenient for patients with symptoms suggesting both upper and lower GI pathology, or for comprehensive screening.
