Can I go to the toilet before a physical examination? 4 taboos to pay attention to during a physical examination

As society develops faster and faster, not only do people know to pay attention to their physical health, but many units and departments will arrange physical examinations for employees to check whether various physical indicators are normal. However, if you do not pay attention to some things, the results of the physical examination will be inaccurate. So, can you go to the toilet before the physical examination? Let’s take a look together below.

It is generally recommended to be on an empty stomach during a physical examination, but you can go to the toilet at this time. Almost everyone knows that checking liver and kidney function, blood lipids, blood sugar, etc. requires the examinee to fast, because the human body is in a relatively basic metabolic state at this time, which can reflect the real situation. Drinking a lot of water before a physical examination will indeed dilute the blood, leading to errors in the test values ​​of blood sugar, blood lipids, blood viscosity, etc. In fact, it is okay to drink a small amount of water (50-100 ml) on the morning of the blood test or the night before. As long as you don't gulp down water or drink hundreds of ml at a time, it will not affect the results of the physical examination. Therefore, patients with hypertension and diabetes do not have to skip medication before a physical examination because they are afraid to drink water. Instead, taking medication before coming for a check-up can help doctors understand their daily physical condition so that they can adjust the treatment plan. However, it should be noted that drinking soy milk, milk, etc. on an empty stomach can cause gallbladder contraction and abdominal bloating, affecting abdominal B-ultrasound results; drinking sweet drinks may cause blood sugar test values ​​to be high.

Here are seven taboos before a physical examination.

1. Avoid excessive fasting. In order to ensure accurate blood test results, many blood tests require patients to fast. But excessive fasting can also affect the test results. If the fasting time reaches more than 18 hours, some tests will have abnormal results. For example, serum bilirubin may increase due to longer fasting time, and blood sugar may decrease to hypoglycemia due to long fasting time. The fasting standard is: the night before blood collection, try to maintain your normal living habits and eat normally; the meal should be light and do not drink alcohol; do not drink coffee or strong tea after a meal. After getting up the next morning, do not eat breakfast, drink little or no water, do not do morning exercise, and calmly go to the hospital to wait for blood drawing.

2. Avoid drawing blood too late. During the day, human metabolism always fluctuates, and the metabolic rate is not at a constant level. Therefore, physical examinations and tests require fasting blood samples to be collected between 7:30 and 8:30 in the morning, and no later than 12:00. If the test is done too late, the test value may be distorted due to the influence of physiological endocrine hormones in the body.

3. Avoid strenuous exercise. Exercise can cause changes in the composition of blood and body fluids. Even mild activity can cause physiological increases in blood sugar and changes in endocrine hormone levels, thus affecting the results. Therefore, do not do strenuous exercise two days before the physical examination, and do not do light activities such as walking one hour before.

4. Avoid the menstrual period. Women's physiological conditions such as menstruation and pregnancy can affect the results of blood tests, so women should not undergo gynecological examinations, routine blood tests, liver function tests, etc. before and after menstruation. It is also best to do breast infrared examination one week after the menstrual period ends.
