How to prepare for a colonoscopy?

In recent years, the incidence of rectal cancer in my country has been increasing. Colonoscopy is an important means of detecting rectal cancer, especially for the early detection of diseases such as intestinal polyps and adenomas. In fact, many intestinal diseases can be cured if they are discovered and treated early. Doing a colonoscopy is not as simple as seeing a doctor. Some preparation is required before the examination. So what are the preparations before a colonoscopy?

Preparation for colonoscopy

1. The examination date will be arranged by the doctor. Examination location: outpatient gastroscopy room. 2. Bowel preparation is required for this examination. 3. Three days before the examination, you should eat a semi-liquid diet with no or little residue, and do not eat vegetables or fruits. If intestinal polyps are suspected and the patient is preparing for electroresection, he or she should avoid eating milk and dairy products. 4. Take 25 ml of castor oil orally at 6:30 am on the day of examination, and do not eat breakfast. Start taking the enema solution at 9:30 am. Mix each packet with 1000ml of boiled water. Drink a total of 3000ml of enema solution within 1.5 hours. If there is still fecal residue in the stool, you need to drink another 1000ml of colon cleansing solution until the excretion is clear water. If nausea or vomiting occurs, tell your doctor or nurse and give them a cleansing enema if necessary. 5. You can eat at 2 pm, but avoid eating liquid food. At 3 pm, the nurse will take you to the outpatient gastroscopy room. 30 minutes before the examination, the nurse will inject you with 10 mg of diazepam and 0.5 mg of atropine to reduce the discomfort caused by the colonoscopy.
