Understanding Colonoscopy at Medi Help Hospital
A colonoscopy is a vital diagnostic procedure used to examine the lining of the large intestine and rectum. Under the expertise of Dr. Vikas Sengar, our team uses a thin, flexible tube equipped with a camera to identify issues like inflammation, ulcers, or abnormal growths.
This procedure is a primary tool for both diagnosing active digestive symptoms and screening for colon cancer. At Medi Help Hospital, we prioritize your comfort and safety during every step of this internal examination.
Who Needs a Colonoscopy?
Your doctor may recommend a colonoscopy if you are experiencing persistent changes in your bowel habits or unexplained abdominal discomfort. It is also recommended as a routine screening for adults over a certain age to prevent colorectal cancer.
Early detection is key in gastrointestinal health, as many conditions are more manageable when caught in their initial stages.
- Chronic constipation or diarrhea
- Rectal bleeding or blood in the stool
- Unexplained weight loss
- Persistent abdominal pain or cramping
- A family history of colon polyps or cancer
- Monitoring existing inflammatory bowel diseases
Preparation for the Procedure
To ensure a clear view of the colon lining, your bowels must be completely empty before the test. Our staff at Medi Help Hospital will provide you with specific instructions on how to prepare.
This usually involves a special liquid diet and the use of prescribed laxatives a day before the procedure. Proper preparation is essential to avoid the need for repeating the test due to poor visibility.
- Consume only clear liquids 24 hours prior
- Avoid red or purple colored drinks
- Follow the laxative schedule provided by our clinic
- Inform Dr. Vikas Sengar about any daily medications
- Arrange for a family member to drive you home
What to Expect During the Procedure
The procedure typically takes between 30 to 60 minutes and is performed in a dedicated procedure room. To keep you relaxed and pain-free, we usually administer a mild sedative or anesthesia.
During the exam, the colonoscope is gently inserted. If Dr. Vikas Sengar finds any polyps or abnormal tissue, they can often be removed or biopsied immediately during the same session without any pain.
Recovery and Aftercare
After the colonoscopy, you will rest in our recovery area until the sedative wears off. You may feel a bit bloated or experience mild gas as the air used during the procedure leaves your system.
Most patients can return to their normal diet immediately, though we recommend resting for the remainder of the day. Our 24/7 nursing team is always available should you have any immediate concerns after going home.
Lifestyle Tips for Colon Health
Maintaining a healthy digestive system goes beyond just clinical procedures. Small changes in your daily routine can significantly reduce the risk of developing colon-related issues.
