As a medical journalist researching digestive-health procedures in Mumbai, I found that persistent abdominal pain, unexplained bleeding, changes in bowel habits and other intestinal symptoms may require more than routine medication. A colonoscopy allows a gastroenterologist to directly examine the lining of the large intestine and rectum and, when necessary, perform procedures such as biopsies or polyp removal during the same examination. For patients researching Colonoscopy in Mumbai, Dr. Vedant Karvir at Globus Gastroenterology Hospital provides gastroenterology, hepatology and therapeutic endoscopy services. The hospital describes him as a Hepato-Gastroenterologist with more than 12 years of experience in these fields.
Colonoscopy in Mumbai: What Is a Colonoscopy?
A colonoscopy is a lower gastrointestinal endoscopic examination used to inspect the entire colon, which forms the lowest major portion of the gastrointestinal tract. A thin, flexible endoscope with a camera is introduced through the anus and guided through the rectum and colon. Images are displayed on a monitor, allowing the doctor to examine the intestinal lining.
Unlike a sigmoidoscopy, which examines only the lower or sigmoid portion of the colon, a colonoscopy is designed to assess the entire colon. This distinction can be important when symptoms may originate farther along the large intestine.
During the examination, the doctor may take tissue samples for laboratory analysis or remove certain polyps. This means colonoscopy can serve both diagnostic and therapeutic purposes.
Why Is a Colonoscopy Recommended?
A gastroenterologist may recommend colonoscopy when symptoms suggest a problem within the large intestine. The Globus Gastroenterology Hospital reference page lists several reasons for lower-GI endoscopy, including investigating abdominal pain, intestinal abnormalities, bleeding and colorectal polyps. It can also allow tissue sampling and removal of certain polyps.
Symptoms that may lead to further evaluation include:
- Blood in the stool or rectal bleeding
- Persistent or unexplained abdominal pain
- Changes in bowel movements
- Unexplained weight loss
- Suspected colorectal polyps
- Symptoms associated with inflammatory bowel disease
- Other unexplained intestinal abnormalities
Not everyone with these symptoms necessarily needs a colonoscopy. The decision depends on the patient’s age, medical history, symptoms, examination findings and previous investigations.
Colonoscopy vs Sigmoidoscopy
Although both procedures use an endoscope to inspect the lower digestive tract, they are not identical.
Sigmoidoscopy examines the rectum and sigmoid colon, while colonoscopy is used to examine the entire colon. The reference material notes that sigmoidoscopy may be recommended when the doctor needs to investigate the lower part of the colon, including symptoms such as rectal bleeding, abdominal pain or altered bowel movements.
A sigmoidoscopy may take approximately 20–30 minutes, while colonoscopy is generally around 30 minutes, although duration can vary depending on findings and whether additional procedures are performed.
If abnormalities such as polyps or suspected cancer are identified during a limited examination, the doctor may recommend a complete colonoscopy to evaluate the remaining colon.
How Is a Colonoscopy Performed?
Before the procedure, the patient is generally given instructions to empty the colon adequately. During the colonoscopy described by Globus Hospital, sedating medication is administered through an intravenous line. The flexible endoscope is then inserted through the rectum and images are viewed on a monitor.
The doctor may take a biopsy or remove a polyp if clinically appropriate. These samples can subsequently be examined to identify abnormal or potentially precancerous changes.
After the procedure, patients may need to rest for some time. Temporary discomfort or bloating can occur because air may be introduced into the bowel during the examination.
The exact preparation, sedation and post-procedure instructions should be discussed with the treating gastroenterologist beforehand.
Preparing for a Colonoscopy
Adequate bowel preparation is an important part of a successful colonoscopy. If stool remains in the colon, it can interfere with the doctor’s ability to see the intestinal lining clearly.
The Globus Hospital guidance states that patients may be advised to follow a specific diet for two to three days before the procedure. Laxatives or a prescribed liquid bowel-cleansing preparation may also be recommended.
Patients should tell their doctor about:
- Existing medical conditions
- Prescription medicines
- Blood-thinning medicines
- Over-the-counter medicines
- Vitamins and supplements
- Known allergies
- Previous reactions to anaesthesia or sedation
Patients should follow the specific bowel-preparation instructions given to them rather than relying on generic online instructions.

Benefits and Potential Risks of Colonoscopy
One important benefit of colonoscopy is that it allows direct visualization of the entire colon. It can help identify abnormalities and enables biopsy or removal of certain polyps during the examination.
However, colonoscopy is an invasive medical procedure and is not completely risk-free. Potential complications can include bleeding, infection, adverse reactions to sedation, abdominal discomfort and, rarely, perforation of the bowel. The likelihood of complications depends on factors such as the patient’s health and whether interventions such as polyp removal are performed.
Patients should discuss individual risks and benefits with their gastroenterologist before undergoing the procedure.
What Happens After a Colonoscopy?
Patients generally spend some time recovering from sedation before leaving the facility. Temporary bloating or abdominal discomfort may occur. If a biopsy or polyp removal was performed, the doctor may provide additional instructions regarding diet, medications and activity.
Patients should arrange appropriate assistance after sedation if advised by the medical team and should follow all discharge instructions.
Any significant bleeding, severe abdominal pain, fever, persistent vomiting or other concerning symptoms after the procedure should be reported to the treating medical team promptly.
