What to pay attention to before and after colonoscopy

Before colonoscopy, we should pay attention to fasting and drinking, clean the intestinal tract completely, rest more, control diet reasonably, use drug treatment, etc. After colonoscopy

, we should completely empty the intestinal tract before colonoscopy, so as to observe the morphology of the intestinal tract and whether there are lesions. Therefore, patients need to fast and drink before examination, and enema should be carried out. only after the intestinal tract is completely emptied can it be conducive to smooth examination. If painless examination is selected during the examination, the patient may be in a semi-conscious state after the examination. Therefore, more rest should be paid attention to. Warm boiled water can be drunk 2 hours after the operation. If the biopsy is taken, the patient should drink water 4-5 hours later and eat porridge the next day after the examination. When taking the biopsy under colonoscopy, the patient should use hemostatic and anti-inflammatory drugs according to the doctor's advice.
