After a colonoscopy, the patient waits for about 60 minutes of observation before discharge, and it is important to have someone to drive the patient home due to the sedative used in the procedure, says Mayo Clinic. It is important to follow the discharge instructions completely, as stated by WebMD.
Some discomfort after a colonoscopy is normal. A feeling of having gas as well as some cramping are normal, but these symptoms generally pass in a short amount of time. In most cases, the patient may go back to his normal diet unless a polyp has been removed, in which case the patient may have to follow a particular diet for a short time. In some cases, the patient needs to stay away from blood thinners, as the process of removing polyps or taking biopsies can cause some bleeding, and thinners hinder coagulation, according to WebMD.
Blood spots in the first bowel movement after the colonoscopy are normal; however, if bleeding continues through the rectum or if blood clots come through with stool, it is important to seek medical attention, states Mayo Clinic. Ongoing or severe pain or tenderness in the abdomen, chills or a fever can be signs of colon perforation, which requires an immediate medical response, as stated by WebMD.
