Hypoglycemia can cause a temporary increase in blood pressure, but the magnitude of the increase in blood pressure caused by hypoglycemia is not very large. Because when there is hypoglycemia, the sympathetic nerve of the body will be abnormally excited, and the sympathetic nerve excitement will cause the contraction force of the heart to increase, and also cause the heart rate to increase. Under these two effects, it will cause a temporary increase in blood pressure, but the magnitude of the increase in blood pressure will not be particularly large, and when the hypoglycemia is corrected, the nerve-induced hypertension will return to normal. In the case of long-term hypertension, the cause of hypoglycemia is generally not considered. The most common causes of hypertension are primary in 95% of cases and secondary hypertension in 5% of patients with hypertension.
