Nowadays, people live in better conditions and have good economic status, but there is a general decline in physical conditions. Therefore, daily physical examination is not to be missing. Before the examination, the doctor will usually advise to pay attention to the fasting examination, so this fasting examination, does it mean that also can not drink water? If you drink water in the morning before the examination, does it have any effect on the examination results? This is a matter of concern to many people, so let’s find out today. To determine whether drinking water before the examination will have an impact on the results of physical examination, we need to start with each item of the physical examination, one by one to analyze: 1, physical examination This type of examination mainly includes auscultation of the heart and lungs, palpation of the abdomen, head and facial organs, etc., these examinations doctors do not need to use any medical equipment, so drink or not, for these examination results, there is no what Therefore, drinking or not drinking water has no effect on the results of these examinations. These examinations include chest X-ray, CT, MRI, mammography, bone density, ultrasound and so on. In these examinations, only the abdominal CT examination when drinking water, for the examination results have an impact, other examinations is no impact. The reason is that after drinking water, this water will enter the gastrointestinal tract, and if you drink too much water, it will cause water to accumulate in the gastrointestinal tract, thus affecting the accuracy of the abdominal CT examination. 3, laboratory tests This is also a very important item in the physical examination, these tests are mainly urine tests and blood tests, the accuracy of these test results and whether fasting is not much relationship between. Do not try to drink water to lower a certain test index. 4, gastroscopy This examination program for fasting and water requirements, is the most stringent clinical examination program, the reason is that there is water inside the intestinal tract, the examination of things can not be seen, it can not be normal examination. Therefore, if you want to perform a gastroscopy, you need to fast (fasting and water fasting) for more than ten hours. Through these analyses, it should be clear that, except for gastroscopy and abdominal CT examinations, drinking water in the morning before the examination will not have any effect on the examination results.
