Patient: For more than 20 years I have been suffering from hypertension, and I have taken many long-acting antihypertensive drugs to no avail. Then I unintentionally found that there was a big difference in blood pressure between lying down and sitting up. My doctor suggested that I read the Baidu library and realized that my reaction was consistent with the situation described in the article. I had already been tested numerous times and had determined that it was postural hypertension and not hypertensive disease. According to the latest pathology literature, there is a significant difference between lying and sitting blood pressure tests, and this has been repeatedly verified. Blood pressure lying flat is lower than sitting or standing and is called postural hypertension. Similarly, there is postural hypotension. Postural hypertension cannot be treated as hypertension. A month ago, I was in Shenzhen, and the difference between lying and sitting pressure was normal. It was completely in line with the range of postural hypertension. But after returning to Changsha, Hunan, almost every day countless tests, the pressure difference between sitting and lying high pressure 30-40 to 180-190. night and nap lying high pressure also has about 150. According to the literature, you cannot take antihypertensive drugs, but can only take drugs such as glutathione, cerebrofacial, creatinine and valium. I take the above-mentioned drugs every day, but my lying and sitting high pressure is 150-160 and 180-190 respectively! But is it normal for postural hypertension to have such high blood pressure. What should I do. Thank you, doctor! Chen Ming: There is no such diagnosis as postural hypertension. According to my understanding, what you have is still primary hypertension combined with postural hypotension. The diagnostic criteria for postural hypotension is a 30/15mmHg drop in blood pressure when standing compared to lying down, and the treatment is still the application of long-acting antihypertensive drugs. To prevent postural hypotension: when getting up or standing up in sitting position, you must move slowly and follow the three 1-minute methods, i.e., wake up and lie flat with eyes open for 1 minute, sit with feet down at the bedside for 1 minute, and stand with support at the bedside for 1 minute. Then move slowly again.
