If there are dizziness symptoms, what causes them? First of all, we need to consider the following factors: first, systemic factors, such as the presence of hypotension, hypertension and anemia? This condition can cause dizziness. Blood pressure can be measured and blood glucose and lipids can be tested. In the second case, some diseases of the ear can also cause dizziness, such as benign positional vertigo, which is very serious and usually accompanied by nausea and vomiting, so you can go to the ENT department for examination and let the doctor determine whether the vertigo is caused by ENT diseases. In the third case, for middle-aged and elderly people, if they have dizziness, they should consider the possibility of cerebral blood supply deficiency, and they can go to neurology for relevant examinations.
