Hypertension is one of the common co-morbidities of diabetes. The prevalence of hypertension among foreign diabetic patients is as high as 40-80%, and 28-40% of diabetic patients in China suffer from hypertension. Diabetes combined with hypertension will accelerate the occurrence and development of cardiovascular disease, stroke, nephropathy and retinopathy, and significantly increase the mortality rate of diabetic patients. Diabetic patients need to have their blood pressure measured at every clinic visit. Patients with blood pressure consistently above 130/80 mmHg should be treated. The goal of treatment is to bring blood pressure down to less than 130/80 mmHg, which will reduce the risk of cardiovascular lesions and microvascular complications. If the initial systolic blood pressure is 130-139 mmHg or diastolic blood pressure is 80-90 mmHg, lifestyle interventions may be given initially for up to 3 months. Treatment of hypertension should include lifestyle interventions that focus on exercise, weight loss, salt restriction, and alcohol restriction. If the initial blood pressure = 140/90 mmHg, medication should be added directly to the lifestyle intervention. Patients with diabetes who have developed microproteinuria should receive antihypertensive therapy regardless of blood pressure, especially early use of renin angiotensin system (RAS) blockers.
