What are the precautions for abdominal examination?

Precautions for abdominal examinations include ensuring fasting time before the examination, taking oral laxatives, guaranteeing adequate water intake, and holding urine. Details are as follows:

1. Ensuring Fasting Time Before the Examination: Fasting for more than 10 hours is usually required before an abdominal examination. Patients are advised to have a meal before sleeping after dinner on the previous day and refrain from eating and drinking on the morning of the actual abdominal examination until after the examination.

2. Taking Oral Laxatives Before the Examination: For certain abdominal examinations, such as colonoscopy, patients are usually instructed to start taking oral laxatives 2 days before the examination to ensure the excretion of food residue in the intestine and clean the intestine.

3. Guaranteeing Adequate Water Intake Before the Examination: For some examination items, such as abdominal CT scans, adequate water intake before the examination is required to ensure that the digestive tract is easy to observe.

4. Holding Urine Before the Examination: For examinations of the urinary and reproductive systems, drinking water and holding urine before the examination is necessary to ensure that the urine volume submitted for examination meets the standard and to avoid false-negative results.
