What preparations should be made before colonoscopy for hemorrhoids

Colonoscopy is a commonly used method for the examination of hemorrhoids. Generally speaking, before using colonoscopy to examine hemorrhoids, patients need to make the following preparations.

1. Psychological preparation:

During the colonoscopy, in order to facilitate the insertion of the mirror, the doctor will fill a small amount of gas into the intestinal tract to expand the intestine. The person being examined will feel bloating and discomfort, but as long as they cooperate well, they can tolerate it. If the person being examined is particularly sensitive to pain or is particularly worried about the examination, he or she can choose to undergo a painless colonoscopy under anesthesia before the examination.

2. Bowel preparation:

Three days before the examination, you should eat some liquid food such as noodles and porridge. It is not advisable to eat vegetables and fruits rich in fiber, and you should fast from dinner the day before. Start taking polyethylene glycol and drinking water for laxatives 8 hours before the examination. When the stool is all light yellow, it means the intestines have been emptied.

3. Preparation for special groups:

Patients with poor cardiopulmonary function or those over 60 years old should first undergo an electrocardiogram and chest X-ray to determine whether they can undergo a colonoscopy. Colonoscopy during menstruation may induce gynecological inflammation in women, so it is best to wait until the menstruation is over before the examination.
