Dizziness when standing up is considered to be caused by postural hypotension. It is usually seen in elderly people or young women. Due to the low blood pressure in general, the vasoconstriction function of the blood vessels is reduced when the position changes, and the patient may become dizzy when standing up, and in severe cases, blackness in front of the eyes or even fall down. It is recommended that patients monitor their blood pressure, especially in the prone position, and if necessary, take oral medication to improve vasoconstriction, and also traditional Chinese medicine. If necessary, acupuncture can be used to improve the phenomenon of dizziness when standing up. At the same time, elastic can also be worn to improve the state of vasodilation and contraction of the lower extremities. For patients with postural hypotension, it is recommended to change position slowly, especially when standing up must be slow to avoid the occurrence of dizziness.
