Blood pressure itself fluctuates, and it is affected by many factors. A few examples of how blood pressure may fall on its own are as follows: First, white coat hypertension, or clinic hypertension. This type of person’s blood pressure is only elevated in the hospital setting, but is completely normal when self-tested at home, or when doing 24-hour ambulatory blood pressure is also in the normal range. In this case, as soon as they leave the hospital setting, their blood pressure is completely normal, so they do not necessarily need to receive antihypertensive medication. Secondly, because of the slight elevation of blood pressure and lifestyle is very much related, when the lifestyle is improved, eat lighter, appropriate exercise, weight control, so that the blood pressure will also come down, not necessarily with the help of drugs. Third, secondary hypertension, such as sleep apnea, adrenal pheochromocytoma, these factors are removed, the blood pressure will be reduced. Of course, most hypertensive patients still need to receive long-term treatment with antihypertensive drugs to keep their blood pressure under control.
