Things to note before doing colonoscopy in the afternoon

Colonoscopy is usually done in the morning because people have not eaten yet and the intestines are relatively clean. At this time, colonoscopy only requires a slight cleaning. However, some people choose to do colonoscopy in the afternoon due to lack of time. In this case, some cleaning is required before colonoscopy. Let's learn about the precautions before colonoscopy.

1. Diet

1. One week before the examination: keep bowel movements smooth. For patients with relatively regular bowel movements, there is no need for strict dietary restrictions; for patients with a history of constipation, they can take fruit laxative tablets or senna leaves to reduce fecal accumulation in the intestinal cavity.

2. 2 days before the examination: Eat semi-liquid food (such as noodles, egg custard, yogurt, porridge, etc.), avoid eating vegetables, fruits and other crude fiber foods.

3. The night before the examination: Eat easily digestible liquid food (such as rice soup, lotus root powder, oatmeal, etc.).

4. On the day of inspection:

a) Those who undergo the examination in the morning: Do not eat in the morning. You may take candy or chocolate 30 minutes before the examination (except for painless colonoscopy).

b) For those examined in the afternoon: Eat easily digestible liquid food in the morning and fast for lunch.

2. Taking medicine

Note: If the colonoscopy is in the afternoon, the medication that was supposed to be taken at 4 a.m. on the day of surgery should be taken at 10 a.m. instead.

1. Magnesium sulfate bowel preparation group:

a) At 4pm the day before the test: Take a 50g packet of magnesium sulfate, dissolve the powder in a large cup of warm water and drink it, then drink about 1500ml of Wenshun within 1 hour. Move around a bit after taking it to excrete all the feces.

b) 4:00 a.m. on the day of examination: take another packet of magnesium sulfate as above. If you have not finished taking the medicine or vomited, please contact the nurse in time to take additional intestinal cleansing measures.

2. Hengkang Zhengqing Group: Take 2 boxes of Hengkang Zhengqing (containing 2 boxes of ABC each) at 4 am on the day of examination, add 2000ml of warm water to dissolve, take 600-1000ml for the first time, and take once every 10-15 minutes thereafter, and finish taking 2000ml within 1 hour. Move around a bit after taking it to excrete all the feces. If you have not finished taking the medicine or vomited, please contact the nurse in time to take additional intestinal cleansing measures.
