What causes a sudden fainting episode in an elderly person over seventy, and what should be done?

Seniors in their seventies who suddenly collapse may be experiencing conditions such as hypoglycemia, hypotension, or insufficient cerebral blood supply. Treatment should be tailored according to the specific underlying cause.

1. Hypoglycemia

If a senior in their seventies has hypoglycemia, the brain may not receive sufficient energy, leading to transient cerebral ischemia and temporary loss of consciousness, which can result in sudden fainting. If the person is conscious after collapsing, they can take glucose tablets or drink sugary beverages. If unconscious, immediate intravenous glucose injection is required.

2. Hypotension

In cases of orthostatic hypotension, when a person stands up suddenly from a sitting or squatting position, cerebral blood flow may temporarily decrease, causing dizziness and other discomforts, which usually improve with rest. If excessive use of antihypertensive medication leads to low blood pressure and fainting, treatment may include saline supplementation or intravenous administration of vasopressor drugs under medical supervision.

3. Insufficient Cerebral Blood Supply

If poor cerebral perfusion in seniors is caused by conditions such as cerebral atherosclerosis or hypertension, symptoms like dizziness and headache may occur, potentially leading to sudden collapse. In such cases, medications like Xuesaitong soft capsules, which help improve cerebral circulation, may be used as directed by a physician to alleviate symptoms.
