What could cause dizziness and blurred vision?

Dizziness and blurred vision are usually associated with conditions such as cerebral infarction, irregular heartbeat, and vasovagal reflex. The specific details are as follows:

1. Cerebral Infarction

When patients develop brain diseases, hardening and narrowing of cerebral blood vessels may occur, leading to cerebral infarction and resulting in cerebral ischemia. When the brain experiences insufficient blood supply and oxygen, the aforementioned symptoms may appear. Patients can take medications such as aspirin enteric-coated tablets or atorvastatin calcium tablets as directed by a physician.

2. Irregular Heartbeat

Poor habits such as chronic sleep deprivation and smoking may lead to an irregular heartbeat, altering hemodynamics and causing inadequate cerebral perfusion, thus resulting in the above symptoms. Patients can take medications such as metoprolol tartrate tablets or atenolol tablets under medical guidance.

3. Vasovagal Reflex

This condition typically refers to a transient reflex regulation by the vagus nerve on blood vessels. This reflex often occurs during sudden postural changes, most commonly triggered by pain, crying, or similar stimuli. Postural changes cause blood vessel dilation, leading to insufficient oxygen supply to the brain and resulting in the aforementioned symptoms. Patients may be treated with dopamine hydrochloride injection or epinephrine hydrochloride injection as prescribed by a doctor.

In addition to the above, these symptoms could also be caused by vestibular dysfunction, hypertension, glaucoma, etc. It is recommended that patients get adequate rest and avoid excessive stress to prevent worsening of the condition.
