People with mild high blood pressure don't get as big of a blood flow boost in their muscles when insulin kicks in, compared to people with normal blood pressure.

People with mild high blood pressure who have trouble using insulin well also tend to have muscles that don’t take in sugar properly and don’t get as much blood flow — suggesting their metabolism and blood vessels might be struggling together.

Insulin might raise blood pressure by revving up the body's 'fight or flight' system and making the kidneys hold onto more salt, which can increase pressure in the blood vessels.

People with mild high blood pressure who aren't taking medicine don't process sugar as well in their muscles and body when insulin is high, which suggests their body is resisting insulin's effects.

Chronic elevation of insulin activates the sympathetic nervous system, leading to increased heart rate, cardiac output, and peripheral vasoconstriction, thereby raising blood pressure.
