Why insulin doesn't work as well in high blood pressure
Insulin resistance in essential hypertension is characterized by impaired insulin stimulation of blood flow in skeletal muscle

Surprising Findings
Insulin-mediated blood flow increase is reduced by more than two-thirds in mild hypertension.
Most people think insulin only affects blood sugar, but it also controls blood flow. The fact that this function is impaired so severely—even in mild hypertension—is unexpected and highlights an early vascular defect.
Practical Takeaways
Monitor blood pressure early—even if it's only slightly elevated—as it may signal broader metabolic dysfunction.

Insulin helps open up blood vessels in your muscles, letting more blood through so nutrients like creatine can get to the muscle cells more easily.
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 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.
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.
