There are many causes of dizziness caused by bending over, mainly in the following areas. First, postural hypotension, due to bending, squatting so that most of the body’s blood is concentrated in the lower limbs, when the moment to get up blood is too late to redistribute, resulting in the brain transient ischemia, hypoxia and cause dizziness, headache. It does not need too much treatment, usually pay attention to slow down the body when getting up, serious cases can take raw pulse drink symptomatic treatment. Secondly, otoliths, mostly induced by rotation of the head and position changes. The main manifestations are dizziness, visual rotation, etc., often accompanied by nystagmus. The diagnosis can be clarified by the postural change test, and can be effectively relieved by manual repositioning treatment. Third, inadequate blood supply to the vertebral artery, when bending low when the head easily induced cervical spine pull, stimulation of the surrounding blood vessels and nerves, thereby compressing the vertebral artery and causing cerebral ischemia, hypoxia, dizziness and headache, taking ginkgo biloba, Chuanxiongzin and other drugs can be symptomatic treatment.
