Fasting does not mean that you cannot drink a mouthful of water.
The non-fasting state can affect the results of blood glucose, blood lipid, liver and kidney function and abdominal ultrasound. Therefore, in general, subjects are required to fast for at least 8 hours and water for more than 6 hours before the physical examination. The so-called “water ban” here can be understood
Do not affect the results of the physical examination, can not “a lot” of water, generally not more than 200ML is appropriate. However, it should be noted that only plain boiled water can be drunk, not drinks, tea, coffee, soybean milk, milk, etc., so as not to affect the physical examination results.
“fasting” is not to take any drugs
For drugs that must be taken every day, especially those that will immediately cause changes in vital signs after being interrupted at will, and even lead to critical illness, must not be interrupted at will! For example: antihypertensive drugs, hypoglycemic drugs, heart rate-slowing drugs, thyroid-related drugs, and other drugs that need to be taken for a long time, such as anticoagulants, antiarrhythmic drugs, antiepileptic drugs, cardiotonic drugs, etc. (Especially for diabetic patients, many drugs should be taken after meals or during meals. You can carry the drugs with you on the day of the physical examination, and wait for blood to be drawn on an empty stomach.
After the completion of the project, eat in time and take medicine in time) In short, patients with chronic diseases who need long-term medication should not stop taking medicine rashly, and should communicate with the doctor before physical examination.
Finally, the fasting time is not the longer the better. The best time for fasting blood collection for physical examination is from 6:30 to 9:30 in the morning, and should not exceed 10:00 at the latest. It is suggested that physical examination in the morning should be carried out sooner rather than later.
