Review Hypertension with diabetes mellitus: physiology and pathologyMitsuru Ohishi. Hypertens Res. 2018 Jun. AbstractElevated blood pressure is closely related to increased circulatory fluid volume and peripheral vascular resistance. Patients with diabetes mellitus experience increased peripheral artery resistance caused by vascular remodeling and increased body fluid volume associated with insulin resistance-induced hyperinsulinemia and hyperglycemia. Both of these mechanisms elevate systemic blood pressure. Thus, fully understanding the pathophysiology of hypertension in diabetes mellitus requires knowing the natural history of type 2 diabetes. Patients exhibit hyperinsulinemia with insulin resistance due to impaired glucose tolerance and early-stage diabetes. Hypertension occurs because of increased body fluid volume. After reaching mid-stage diabetes the vascular remodeling has progressed and peripheral vascular resistance also contributes to hypertension. Moreover, vascular remodeling strongly influences diabetic complications. Specifically, afferent arteriolar remodeling during diabetic nephropathy leads to increased glomerular pressure. Thus, treatment with a renin-angiotensin system inhibitor that promotes renal damage regression is critical to lowering the systemic blood pressure and dilating efferent arterioles to reduce glomerular pressure.

What should your blood pressure be with type 2 diabetes?Blood pressure should be below 140/80mmHg for people with diabetes or below 130/80mmHg if you have kidney or eye disease or any condition that affects blood vessels and blood supply to the brain. But it is important to speak to your healthcare team about your individual target.
Is blood pressure and blood sugar related?Yes. It turns out that hyperglycemia can contribute to hypertension. High blood sugar can increase blood pressure through two primary means. First, untreated hyperglycemia can lead to nerve and blood vessel damage.
Can diabetes trigger high blood pressure?High blood pressure is twice as likely to strike a person with diabetes than a person without diabetes. Left untreated, high blood pressure can lead to heart disease and stroke.
Why does type 2 diabetes cause hypertension?Patients with diabetes mellitus experience increased peripheral artery resistance caused by vascular remodeling and increased body fluid volume associated with insulin resistance-induced hyperinsulinemia and hyperglycemia. Both of these mechanisms elevate systemic blood pressure.
