Low blood sugar low blood pressure can donate blood

Hypoglycemia and hypotension generally do not donate blood.

Hypoglycemia refers to low glucose concentration in the blood. Hypotension refers to low blood pressure. If you donate blood at this time, it can cause dizziness, nausea, vomiting and other discomfort symptoms. It will cause low blood pressure, affecting blood circulation, thus increasing the risk of complications after donation, so it is generally not recommended for such patients to donate blood.

For patients with hypoglycemia and hypotension, proper aerobic exercise, adequate sleep and regular rest time should be noted to help alleviate symptoms.
