Do you know? 25% of Chinese residents have abnormal blood pressure, and one in every 10 people has higher blood sugar than normal. More than half of them do not know that their blood pressure and blood sugar are abnormal. Even if someone often tests blood pressure and blood sugar, they cannot find their abnormality. Why?

[Case 1] Mr. Zhang was diagnosed with coronary heart disease when he was in the hospital due to chest tightness and shortness of breath. The doctor said it was related to hypertension . Mr. Zhang was very puzzled about this. He often measured his blood pressure, and it was within the normal range. It was impossible to have hypertension? I asked him carefully about the time to measure his blood pressure, and the truth was revealed!

It turns out that Mr. Zhang is used to measuring his blood pressure after getting up at nap every day. Sometimes he will also measure his blood pressure before going to bed at night. Most of them are around 130/80mmHg, which is quite different from the diagnosis standards of 140/90mmHg. Therefore, he thinks his blood pressure is normal, and he is in his early 50s. He often hears that his blood pressure will rise when he gets older. Compared with those in his fifties and sixties, his blood pressure is maintained well!

In fact, this confidence made Mr. Zhang miss the opportunity to detect hypertension early, because he missed the most important time point for discovering hypertension in time, which led to the long-term existence of hypertension and triggered coronary heart disease. This time point was early in the morning.

You should know that the maximum blood pressure of the human body throughout the day occurs during the morning waking up to before breakfast. Some people's peak blood pressure may continue to around 10:00 in the morning. After that, the blood pressure will gradually drop. After lunch, the period when the blood pressure is relatively low throughout the day, and then it will rise. A small peak will appear again in the evening, but it will not be higher than the morning blood pressure. After that, the blood pressure will drop rapidly. When you go to bed, your blood pressure will be 10%-20% lower than the morning blood pressure.

The period when Mr. Zhang measured his blood pressure was exactly two periods with lower blood pressure throughout the day. In fact, after testing, Mr. Zhang's blood pressure when he woke up in the morning was around 150/100mmHg. He was a typical hypertensive patient. But he didn't know it himself, so of course he did not take any intervention measures. cardiovascular and cerebrovascular disease occurred unknowingly.

Summary: The blood pressure measured before breakfast is the most valuable and helps to detect hypertension in time. For people with hypertension, paying attention to blood pressure monitoring during this period is also the top priority for daily blood pressure monitoring.

[Case 2] Ms. Li urinary tract infection occurred repeatedly after menopause . The doctor asked her to check her blood sugar to see if she had diabetes . Ms. Li said that she had tested fasting blood sugar many times, but none of them exceeded the normal value of 6.1mmol/L, and she should have no diabetes. However, glucose tolerance test showed that her blood sugar was 11.6mmol/L 2 hours after meals, which exceeded the 11.1mmol/L diabetes diagnosis standard, indicating that she had diabetes, which is one of the main reasons for the recurring urinary tract infections.

Many people believe that only fasting blood sugar is high if is high after meals, and most physical examinations are only measured to eliminate diabetes. However, the fact is: among Chinese residents, about half of the people first experience postprandial blood sugar increase, while fasting blood sugar is normal, especially after being overweight and over 45 years old, this situation is more likely to occur.

The principle is very simple. After a night of sleep, the body's physiological activities are relatively slow, the secretion load of islet cells is small, fasting blood sugar is easy to maintain at normal levels, blood sugar rises rapidly after meals, and damaged islet cells cannot secrete enough insulin in time, resulting in a significant increase in blood sugar after meals. The most important thing is that three meals a day make two-thirds of the body in the post-meal state throughout the day, so the increase in post-meal blood sugar will be more harmful to the human body.

Summary: Screening for diabetes requires the test of fasting blood sugar and blood sugar 2 hours after the meal. Even if the fasting blood sugar is normal, the blood sugar 2 hours after the meal may exceed the normal value of 7.8 mmol/L, and may be greater than the diabetes diagnosis standard of 11.1 mmol/L, and can also be diagnosed as abnormal blood sugar or diabetes. For people with diabetes, blood sugar should be tested for 2 hours after meals. Remember that low fasting blood sugar does not mean that there is no diabetes, nor does it mean that blood sugar control meets the standards.
