The preparations needed before doing colonoscopy include bowel cleansing, basic examination, and adjustment of mindset.

Intestinal cleansing: patients who want to do colonoscopy should follow the doctor’s instructions to take intestinal cleansing medication before the examination, usually about 6 hours before the examination to start taking. It should be noted that patients can not eat during the intestinal cleansing medication, and patients should not drink water about 4 hours before the colonoscopy, so as to avoid affecting the results of the examination.
2. Basic examination: patients suffering from central nervous system diseases or heart diseases should follow the doctor’s instructions to check the lesions before colonoscopy to avoid discomfort to the patient’s organism because of not understanding the patient’s condition.
3. Adjustment of mentality: patients should adjust their mentality in time before colonoscopy, avoid too much emotional tension, and try to keep a calm mentality, which is conducive to the smooth progress of colonoscopy.
