Second, for the general halo, caused by some systemic diseases, mainly to the feeling of dizziness, feeling top-heavy. Classification and common disease dizziness is a common symptom, not an independent disease.

Cause

Dizziness is caused by dilated blood vessels and increased blood flow, which causes a decrease in blood in the brain. This phenomenon may occur because it has been exposed to the hot sun for too long, and the time for taking a hot bath is too long, or it is nervous and angry. In addition to the above reasons, lack of vitamins, abnormal hormone secretion, menopause or autonomic nervous disorders are also factors that cause dizziness.

There are many causes of dizziness and tinnitus. First, it should be identified whether vertigo is central or peripheral. Should also understand the cause of dizziness and accompanying symptoms, such as otogenic vertigo often accompanied by tinnitus and hearing loss, common in Meniere disease, inner ear injury and so on. In the case of Meniere's syndrome, hearing will gradually decrease with the onset of the disease. It is recommended to go to a regular hospital for hearing function tests and vestibular function tests. If the otogenic problem is ruled out, it is recommended that the patient go to the Department of Neurology and do a brain examination. Meniere's disease used to be called Meniere's disease. It is the most typical vertigo caused by inner ear disease. The pathological change is endolymphatic water. The incidence is more common in middle-aged people.
