Patients with symptoms such as vertigo, nausea, and vomiting may be caused by three major diseases, namely cerebral infarction, cerebral hemorrhage, and Ménière’s disease. Cerebral infarction is a type of clinical syndrome in which localized ischemic and anoxic necrosis of brain tissue occurs due to impaired blood supply to the brain patch caused by various reasons, thus causing corresponding neurological deficits. Most of them develop in the quiet or sleep state, and symptoms such as dizziness, vertigo, nausea, vomiting, limb numbness and hemiparesis will occur. Cerebral hemorrhage is due to non-traumatic intracerebral parenchymal hemorrhage and has a high lethality rate. It usually develops suddenly during emotional stress or activity and is often associated with headache, nausea, vomiting, vertigo and varying degrees of impaired consciousness, such as drowsiness or coma, due to increased intracranial pressure. Meniere’s disease is caused by fluid accumulation in the membranous vagus due to a variety of causes. Episodes of vertigo with tinnitus, hearing loss and nystagmus may occur, and in severe cases may be accompanied by nausea, vomiting, pallor and sweating, and the episodes are brief, rarely lasting more than 2 weeks. If patients have vertigo, nausea, vomiting, etc., they should consult a local hospital as soon as possible to improve relevant examinations such as brain CT to exclude these three lesions and treat them symptomatically according to the specific causes.
