A colonoscopy is a medical procedure that allows doctors to examine the inner lining of the large intestine, which includes the colon and rectum. The procedure is performed using a thin, flexible tube called a colonoscope. This tube has a tiny camera attached to its end, allowing the doctor to visually inspect the intestine for any abnormalities such as polyps, ulcers, or tumors.
Colonoscopies are important as they can help diagnose issues such as colon cancer, inflammatory bowel disease, and other gastrointestinal problems. They are also used as a preventative measure to screen for colon cancer, especially in individuals over the age of 50 or those with a family history of the disease.
Dietary Restrictions: Several days before your colonoscopy, you may be advised to limit or avoid high-fiber foods. The day before the procedure, you will likely be instructed to consume only clear liquids.
Bowel Prep: To ensure that the colon is empty, you will be given specific instructions on how to clean out your bowel. This usually involves taking a strong laxative and possibly using an enema.
Medications: Inform your doctor of any medications you are taking, as you may need to adjust your usual dose for the procedure. This is especially important if you are taking blood thinners or have diabetes.
Arranging Transportation: You will need someone to drive you home after the procedure, as You will be given medication to help you relax or even sleep during the colonoscopy.
You will lie on your side while the doctor slowly feeds the colonoscope through your rectum and into the colon.
The procedure usually takes about 30 to 60 minutes. The doctor may take tissue samples or remove polyps during the colonoscopy.
You will be monitored until the effects of the sedatives wear off.
You may feel bloating or mild cramps, but this usually passes quickly.
Your doctor will discuss the results with you and provide further instructions.
Avoid driving or operating machinery for 24 hours after the procedure.
