relationship between hypertension and diabetes

Diabetes and hypertension are inextricably linked, they are each other "curse", reinforce each other, which is mainly manifested in the following aspects:
① diabetes incidence of hypertension, diabetes, hypertension incidence is much higher than normal blood pressure. Many people are first found high blood pressure, diabetes, and then found that some of diabetic patients found to have high blood pressure at the same time, the first few patients have diabetes, the recurrence of high blood pressure. As in the detection of diabetes gradually increased blood pressure after a few years, you should be careful to check kidney function.
② high blood sugar more insulin to stimulate insulin secretion, resulting in hyperinsulinemia. Excessive insulin not only promotes renal tubular sodium reabsorption, causing sodium retention, but also stimulate the sympathetic nervous excitement, and thus make vasoconstriction, increased peripheral resistance, elevated blood pressure naturally.
③ occurrence and development of diabetic nephropathy can cause and aggravate high blood pressure in people with diabetes, and to target organs such as the heart, blood vessels, eyes, nervous system diseases increased.
④ Some antihypertensive drugs can affect diabetes control, as well as aggravate high blood sugar, such as loss of potassium-sparing diuretics, β-blockers.
