What causes sudden fainting and vomiting?

Sudden fainting and vomiting are generally caused by insufficient cerebral blood supply, epilepsy, hypertension, or other reasons. It is recommended that patients receive treatment under a doctor's guidance through methods such as massage or medication.

1. Insufficient Cerebral Blood Supply: This condition is usually caused by reduced blood flow to the brain or inadequate cardiac pumping, and is often accompanied by symptoms such as headache and blurred vision, which may lead to sudden fainting and vomiting. Treatment typically involves medications such as flunarizine hydrochloride tablets or buflomedil hydrochloride injection, as directed by a physician. Regular head massage may also help improve blood circulation and relieve symptoms.

2. Epilepsy: Epilepsy is commonly caused by congenital or acquired factors and is often associated with sudden collapse and loss of consciousness, potentially resulting in episodes of fainting and vomiting. Under medical supervision, treatment generally includes antiepileptic drugs such as carbamazepine tablets or lamotrigine tablets.

3. Hypertension: Hypertension is usually caused by genetic or environmental factors and often presents with symptoms such as headache and neck stiffness, which may lead to sudden fainting and vomiting. Under a doctor’s guidance, treatment typically involves antihypertensive medications such as valsartan capsules or spironolactone tablets.
