Is a colonoscopy painful?

Colonoscopy will cause some slight discomfort, which is generally acceptable to most people. You should eat a light diet three days before the examination, fast on the day of the examination, and take medication to excrete feces before the examination. If you have had surgery before or have intestinal adhesions, you will experience some bloating and pain. Don't be too nervous, you can take deep breaths to reduce the pain.

Things to note when doing anorectoscopy:

1. If the discharge after taking the medicine contains feces or fecal fluid, you should inform the colonoscopy medical staff in time for further intestinal treatment.

2. In order to facilitate the insertion of the endoscope or to see the mucosal morphology of the intestinal cavity clearly, the doctor sometimes needs to inject a small amount of air into the intestinal cavity to expand or expose the intestinal cavity. At this time, the patient often feels abdominal distension and a feeling of defecation.

In addition, due to the tortuous curvature of the large intestine, experts say that sometimes the curvature of the intestine is too large, or the patient has a history of abdominal surgery or intestinal adhesions, and the patient will feel some bloating and pain when the colonoscope is passed through. It is best to take deep breaths at this time and not to be overly nervous, otherwise intestinal spasms may occur easily, which will increase the difficulty and risk of the doctor inserting the endoscope and prolong the operation time.

3. The examination takes about 15 minutes on average. Sometimes it may take a little longer due to individual differences or abnormalities in the large intestine.
