What to pay attention to the night before a routine physical examination

Don't deliberately change your daily diet, work and rest status, and don't do anything that may interfere with metabolism and physiological indicators. It is generally recommended to stop eating after 8 pm, drink as little water as possible after 10 pm, and ensure 7-8 hours of normal sleep.

Last week, I accompanied my cousin to get the physical examination report. The night before, she celebrated her birthday with her roommate and ate an entire portion of durian millet. She also drank two cups of bubble milk tea and stayed up until 1 o'clock to catch up on dramas. The results showed that her fasting blood sugar had risen to 6.3 and her triglycerides were also above the normal line. When the doctor asked her about the situation, she asked her to go back to her normal diet for a week and then come back for a review. This week, all indicators returned to the normal range, which made me nervous for several days.

Of course, there is no need to make excessive adjustments for the physical examination. It has been said before that you should be vegetarian and abstain from oil for three days before the physical examination. It is not necessary - if you often eat takeout and have many dinner parties, the blood lipid values detected after deliberately eating vegetarian for three days have no reference significance at all, and it is equivalent to doing it in vain. There are actually different opinions in the industry on whether you can drink water. It doesn’t mean that a little water won’t work. If you have a chronic disease and need to take anti-hypertensive, anti-hyperglycemic, or anti-coagulant drugs for a long time, it is perfectly fine to take them with half of the water. On the contrary, stopping the medicine hastily is more likely to cause blood pressure spikes and blood sugar fluctuations. My grandma During last year’s physical examination, I specifically asked the nurse at the consultation desk, and she made it clear that antihypertensive drugs must be taken on time. The impact of the two sips of water on the results can be ignored. As long as you don’t drink milk tea, coffee, carbonated drinks, and functional drinks, these things will either raise blood sugar, or affect the heart rate and liver enzyme values.

In addition to diet, pay more attention to exercise. If you have a fitness habit, don't arrange high-intensity strength training or long-distance running the night before. My colleague went for a physical examination the next day after doing leg exercises. The creatine kinase was twice as high. He almost thought he had rhabdomyolysis. After three days of rest, he returned to normal after checking again. If there is a need for gynecological examination or routine urine examination, do not do vaginal douching or have sex the night before, otherwise the results of routine leucorrhea, TCT or urine specimens may be biased. If you are taking high-dose vitamin supplements or taking traditional Chinese medicine decoctions recently, it is best to stop for one day in advance. I once had a friend who took high-concentration vitamin C for a long time and took it as usual the night before. The next day, the urine test for occult blood showed a false negative, which means that the test was in vain.

In fact, you don’t need to think too complicated about the preparation before the physical examination. To put it bluntly, don’t act blindly or deliberately “pretend to be healthy”. Only the results can best reflect your true physical condition. This avoids the need to find a lot of abnormalities and have to re-examine repeatedly, which is a waste of money and time.
