What Does a Gastroenterologist Do?

If you've been referred to a gastroenterologist — or you're searching for one in Bengaluru — you may be wondering exactly what this specialist does and whether they're the right doctor for your concern. This guide breaks it down clearly.

Who Is a Gastroenterologist?

A gastroenterologist is a doctor who specialises in diagnosing and treating conditions that affect the digestive system. This includes everything from the oesophagus and stomach to the small intestine, large intestine, liver, gallbladder, and pancreas.

They complete a standard medical degree followed by several additional years of specialised training in gastroenterology — making them distinctly more equipped than a general physician for complex or persistent digestive concerns.

At MIMAS Health Care in Indiranagar, Bengaluru, Dr. Muni Reddy practises as both a gastroenterologist and a GI Surgeon. This means he can manage your condition medically and, when surgery is needed, perform minimally invasive procedures himself — without referring you elsewhere.

What Conditions Does a Gastroenterologist Treat?

A gastroenterologist commonly diagnoses and manages:

• Acid reflux and GERD (gastroesophageal reflux disease)

• Irritable Bowel Syndrome (IBS) and inflammatory bowel disease (Crohn's disease, ulcerative colitis)

• Liver disease — including fatty liver, hepatitis, and cirrhosis

• Gallbladder disease and bile duct disorders

• Pancreatitis and pancreatic conditions

• Colorectal polyps and colorectal cancer screening

• Stomach ulcers and H. pylori infection

• Hernias and complex abdominal conditions

• Difficulty swallowing or unexplained weight loss

• Chronic bloating, nausea, or irregular bowel habits

If you're experiencing any of these, a consultation with a Gastro Specialist in Bengaluru is the right starting point — not a wait-and-watch approach.

What Procedures Can a Gastroenterologist Perform?

Beyond consultations and medication management, gastroenterologists are trained to perform both diagnostic and therapeutic procedures:

Upper GI Endoscopy (OGD)
A thin, flexible camera is passed through the mouth to examine the oesophagus, stomach, and duodenum. Used to investigate acid reflux, ulcers, difficulty swallowing, and unexplained upper abdominal pain.

Colonoscopy
A camera examination of the entire large intestine. Used for colorectal cancer screening, investigating blood in stool, diagnosing IBD, and removing polyps before they develop into cancer.

ERCP (Endoscopic Retrograde Cholangiopancreatography)
A specialised endoscopic procedure used to treat bile duct stones, blockages, and pancreatic duct conditions — avoiding the need for open surgery.

Laparoscopic Surgery
For GI Surgeons like Dr. Muni Reddy, this extends to minimally invasive keyhole surgery for gallbladder removal, hernia repair, and other abdominal conditions — with significantly less pain and faster recovery than traditional open surgery.

At MIMAS Health Care's Endoscopy Centre in Indiranagar, all procedures are performed personally by Dr. Muni Reddy. Patients are never handed to a junior doctor for their procedure.

How Is a Gastroenterologist Different From a General Physician?

A general physician can prescribe antacids or basic medication for common digestive complaints. But when symptoms are persistent, worsening, or need investigation with a camera or surgical correction, you need a dedicated gastroenterologist.

The difference matters most when symptoms are ambiguous. Chronic bloating could be IBS — or it could be something that requires a colonoscopy to rule out. A gastroenterologist knows which is which, and how to find out.

How Is a Gastroenterologist Different From a GI Surgeon?

Some gastroenterologists manage conditions medically but do not perform surgery. A GI Surgeon — like Dr. Muni Reddy at MIMAS Health Care — combines both. This means fewer referrals, a single point of care, and a doctor who understands your case from both the medical and surgical perspective before making any recommendation.

When Should You See a Gastroenterologist in Bengaluru?

Book a consultation if you're dealing with any of the following:

• Recurring stomach or abdominal pain lasting more than a few days

• Heartburn or acid reflux more than twice a week

• Blood in stool — whether bright red or dark and tarry

• Unexplained weight loss

• Difficulty swallowing food or liquids

• Persistent nausea, vomiting, or bloating

• Yellowing of the skin or eyes (jaundice)

• You're over 45 and haven't had a colonoscopy screening

Early specialist assessment consistently leads to better outcomes. The longer complex digestive conditions go undiagnosed, the narrower the treatment options become.
