Dizziness is a series of symptoms such as a dizzy feeling in the head, feeling heavy or with rotating vision, nausea and vomiting. There are many causes of dizziness, including hypertension, cerebral artery insufficiency, cerebral infarction, posterior circulation ischemia, and other diseases that are common in the elderly. Elderly people who experience dizziness for a long time should go to the hospital for a cranial CT or MRI to see if there are intracranial lesions. Blood pressure, blood sugar, and lipids also need to be monitored, and if these problems exist, they need to be treated with related medications. The symptoms of dizziness in young people are usually paroxysmal positional vertigo, which may be caused by cold, cervical spondylosis, or unreasonable life and rest schedule. In these cases, the first thing you need to do is to change your routine, and if the symptoms do not ease, go to the hospital in time for treatment, which is generally better for young people. If there are symptoms of long-term dizziness, you need to be alert to intracranial tumors.
