Sudden dizziness and nausea may be associated with transient ischemic attacks, Meniere’s disease, otolithiasis and other conditions.
1. Transient ischemic attack: It is mainly a symptom of insufficient supply of carotid artery or vertebral-basilar artery system, which causes focal cerebral ischemia, resulting in dizziness or vertigo and other symptoms, and the duration of each attack is very short.
2. Ménière’s disease: It is an inner ear disease of unknown cause, usually sudden and rotational, the patient is lucid, and the duration is between 20 minutes and 12 hours, and it may recur, and the more frequent the recurrence, the longer the duration, and the shorter the intervals will be. The attacks are accompanied by nausea, vomiting, and cold extremities.
3. Otolithiasis: Otoliths dislodged from the oval capsule into the semicircular canals can cause otolithiasis. Otoliths dislodged into the lymphatic fluid in the semicircular canals stimulate the internal hair cells, thus causing damage to the hair cells, which further causes nausea and dizziness in the patient.
There are many causes of sudden vertigo and nausea. The patient should go to the hospital in time to improve the examination, identify the cause of the disease, and then follow the doctor’s instructions for treatment.
