Do I need to drink laxatives for colonoscopy during physical examination

Physical examination and colonoscopy usually require taking laxatives. Taking laxatives before colonoscopy is to thoroughly clean the intestines, ensure clear vision during the examination, and improve the accuracy of the examination results. Before colonoscopy, the doctor will prescribe laxatives such as compound polyethylene glycol electrolyte powder, which flush the intestines with a large amount of water to help eliminate feces and intestinal contents. After taking laxatives, there may be multiple watery stools, which is a normal phenomenon. 1-3 days before the examination, it is necessary to adjust to a low residue diet and avoid consuming high fiber foods. Start taking laxatives 4-6 hours before the examination, and follow the doctor's advice for the specific time. Some hospitals may use different types of laxatives such as sodium phosphate oral solutions, with slight differences in medication methods and precautions.

In rare cases, it may not be necessary to take laxatives, such as when only undergoing sigmoidoscopy or when there are contraindications such as intestinal obstruction. People who are allergic to laxative ingredients should inform their doctor in advance and may switch to other cleaning methods. Patients with severe heart disease or renal insufficiency need to be evaluated before deciding whether to use laxatives. Children or elderly people taking laxatives should adjust their dosage under the guidance of a doctor.

After colonoscopy, it is recommended to supplement water and electrolytes in moderation, such as drinking diluted saline or oral rehydration salts. The initial diet is mainly liquid or semi liquid, gradually transitioning to a normal diet. If persistent abdominal pain or rectal bleeding occurs after examination, seek medical attention promptly. Maintaining a regular daily routine and balanced diet can help maintain intestinal health.
