What is the cause of temporary blindness for a few minutes?

A few minutes of short-term blindness may be caused by hypoglycemia, orthostatic hypotension, cervical spondylosis, etc.

1. Hypoglycemia may be

caused by insufficient sugar intake, insufficient glucose production, excessive glucose consumption, excessive glucose conversion, etc., and the patient may experience temporary fainting, thus feeling short-term blindness for a few minutes.

2. Orthostatic

hypotension may be caused by insufficient blood volume, adverse drug reactions, impaired homeostasis regulation function, abnormal autonomic nervous function, etc., and the patient may experience short-term blindness for a few minutes or even fainting symptoms due to inability to increase sympathetic vasoconstriction when standing.

3. Cervical

spondylosis may be caused by degeneration of the intervertebral disc, flat vertebral arch development, cumulative damage, etc. When the diseased site compresses the vertebral artery and causes insufficient blood supply, the patient may experience short-term blindness for a few minutes, nausea, vomiting, hearing loss, etc.
