Lie for a long time to stand up dizziness there are two possibilities, as follows: First, the occurrence of postural hypotension, resulting in a transient whole brain blood supply deficiency, when the blood supply deficiency involved in the posterior circulation will produce dizziness. In this case, as long as the movement is slowed down when you get up, there is an adaptation process, from lying to sitting, and then to standing, dizziness will generally be gradually relieved, or avoid triggering. Secondly, benign paroxysmal positional vertigo occurs, which is a disease caused by vestibular dysfunction of the inner ear, and the lesions are in the membrane vagus and semicircular canal of the cochlea. Most of the patients lie down for a long time, because the activity is reduced, the balance organ of the ear is desensitized, and dizziness is easily produced in the active state. You can take Betahistine and Difenidol orally to stop dizziness and treat the symptoms, and combine with Chinese medicine, such as Powerful Dizziness Tablets and Vertigo Ning Tablets.
