If your blood pressure is normal when you are lying down, but high when you are sitting down, it may be caused by inaccurate measurement, or it may be early hypertension.
1. When you lie down, your arms are usually placed on both sides of your body, and the sphygmomanometer is also placed on the side, which ensures that your heart is at the same level as your upper arm and the sphygmomanometer, so the measurement is relatively accurate.
2. When sitting up, if you don’t keep the upper arm at the same level as the sphygmomanometer and the heart, it may lead to inaccurate measurements, or if you just get up and take measurements immediately, it may cause slightly high blood pressure, in which case, after paying attention to correcting the measurement method, the general difference will not be too great.
3. There is also a kind of early hypertension patients lying down, cardiac vascular compensatory function is good, may measure the blood pressure value of the normal range, but sitting and standing position may be restored to the true level of blood pressure, such as this case, as long as to determine the standardization of measurement criteria, but also to the higher blood pressure shall prevail in order to determine the overall level.
If you are unable to determine whether you have high blood pressure yourself, it is recommended that you go to a hospital or clinic for measurement.
