At the end of the year and the beginning of the year, many units will organize employees to undergo physical examinations. For some examination items that need to be carried out on an empty stomach, some people often do it Unclear: Some people think that if we just eat something and drink some water, how much impact will it have? Some people think that they need to have a fasting physical examination the next day, so they should eat a full meal the night before to reserve energy; some people are worried that eating will affect the results of the physical examination, and even start fasting the night before the physical examination. Got it…【600D Oxford cloth】
Why do some inspection items require subjects to What about going for a checkup on an empty stomach? This is because after eating, different ingredients in the food will affect the test results to varying degrees. For example, if you collect blood after eating, the food will decompose and enter the blood, which will increase the serum concentration and affect the test results of various indicators, such as: transaminases and triglycerides; consuming animal blood can cause fecal occult blood to show a false positive; After eating, the gallbladder contracts, which affects the development during ultrasound examination and makes it easy to miss the lesion; in addition, after eating, the food flows into the gastrointestinal tract, which will also affect the development to a certain extent during abdominal ultrasound examination, making it difficult to distinguish. Normal abnormality becomes more difficult. Therefore, for some health examination items, such as blood drawing, abdominal ultrasound, etc., it is usually recommended to perform them on an empty stomach.
So, how can we truly achieve fasting? Is it enough to just get up in the morning and skip breakfast? In fact, that’s not entirely true. In addition to not eating breakfast or drinking water on the day of the physical examination, you should also start to maintain a light diet and regular work and rest three days before the physical examination, especially avoid eating high-fat foods, and avoid eating high-fat foods the day before the physical examination. Stop eating after dinner, and try not to eat dinner too late to ensure that the dinner eaten the day before can be completely digested by the time of the physical examination. The digestion of food usually takes 8 hours. 【Oxford cloth manufacturer】
Of course, drawing blood on an empty stomach does not mean that the subject Drawing blood when a person is very hungry will also affect the results of the test due to changes in functions. In addition, people in an extremely hungry state are also prone to cold sweats, dizziness, and fainting due to low blood sugar. , or even hypoglycemic shock. Therefore, when doing physical examinations, it is best to arrange items that require fasting earlier, preferably between 7:30 and 10:00 am.
In addition, it should be noted that for some patients with chronic diseases who need to take medicine for a long time, some people are worried about taking it. Medications will affect the results of the physical examination and stopping the medication without authorization on the day of the physical examination is actually very dangerous. For example, for some hypertensive patients, because blood pressure is usually higher in the morning, if they do not take antihypertensive drugs for a fasting physical examination, then It is likely to cause a sudden spike in blood pressure and affect health. Generally speaking, people with chronic diseases who need to take medicine for a long time can take medicine as usual before the physical examination and inform the doctor during the physical examination. Patients with chronic diseases such as diabetes should carry their usual medications with them. After the fasting check is completed, they can take the medication as usual. Do not delay for too long, causing missed doses and causing fluctuations in the condition. 【Tent Oxford cloth】
