cause of sudden drop in blood pressure
A sudden drop in blood pressure can be caused by a rapid change in health or certain medications. It may also signify an underlying medical problem such as thyroid issues. As long as there are no symptoms, low blood pressure in an otherwise healthy person generally is not a concern.
Diuretics will lower blood pressure, too, by reducing the amount of fluid in the body. Some antidepressants, anti-anxiety medications, drugs for Parkinsonâs disease and drugs for erectile dysfunction can also cause drops in blood pressure.
