Diabetes and hypertension are independent risk factors for atherosclerotic heart disease. Diabetic patients often develop hypertension, which greatly increases the risk of atherosclerotic heart disease, stroke, nephropathy and retinopathy and the disease process. It significantly affects the health of patients and the prognosis of the disease, so timely diagnosis and treatment are needed. Reports on the incidence of hypertension in diabetic patients vary and range from 10% to 80%. The incidence of hypertension in different types of diabetic patients is different and each has its own characteristics: Type 1 diabetic patients with hypertension or elevated blood pressure are only seen in those with high microalbumin excretion, and the incidence of hypertension in those with low microalbumin excretion and those without urinary protein excretion does not differ from the normal population. type 2 diabetic patients with blood pressure related to age, obesity, blood glucose, lipids, nephropathy and insulin levels, of which blood glucose Poor control of blood glucose is the most important risk factor, and altered renal function and dyslipidemia also play an important role. Hypertension in type 1 diabetes is most common in diabetic nephropathy, and primary hypertension also occurs. Systolic hypertension is more frequent in elderly diabetic patients and can also occur at other ages. Recumbent hypertension with standing hypotension occurs most often in the presence of autonomic neuropathy. In most patients with diabetic hypertension, there are no vascular or other complications at the beginning, and symptoms may not be obvious. However, as the disease progresses and in old age, a variety of complications and symptoms may occur: damage to the kidneys may manifest as proteinuria, swelling, weakness, and lethargy. Injury to the heart can lead to abnormal left ventricular function and congestive heart failure; injury to the cerebral vessels can lead to stroke. Diabetic patients with autonomic dysfunction often have recumbent hypertension with standing hypotension and so on. Therefore, diabetic patients can not always keep their eyes on blood sugar, must often see a doctor to detect and treat complications as early as possible. Treatment of diabetic hypertension, including non-pharmacological and pharmacological treatment: I. Non-pharmacological treatment 1. Diet: reduce caloric intake and control blood sugar. Nutritional balance, reduce the intake of saturated fat, and reduce the intake of protein appropriately in patients with diabetic nephropathy; limit salt appropriately. 2.Weight reduction: maintaining ideal body weight is one of the methods to treat hypertension and diabetes. Clinical experiments have confirmed that reducing weight can lower blood pressure and improve blood sugar control. 3, exercise: regular aerobic exercise can help reduce weight and lower blood pressure and serum glucose levels, the amount of exercise needs to be gradual, according to the specific circumstances of the patient to choose the appropriate amount of exercise. Second, drug therapy: diabetic hypertension antihypertensive treatment, it is generally believed that blood pressure ≥ 140/90mmHg, after three months of non-pharmacological treatment still no effect, should consider drug therapy. 1, ACE inhibitors: commonly used drugs are captopril, enalapril, etc., with vasodilatation, lower blood pressure, prevent water and sodium retention, reduce insulin resistance, increase sensitivity to insulin and other effects. These agents can improve glomerular filtration rate and reduce proteinuria by reducing glomerular hypertension. In both type 1 and type 2 diabetic patients, the efficacy is good. 2, calcium channel blockers: commonly used drugs such as, cardiac pain, niduldipine, amlodipine, etc.. In the treatment of diabetic hypertension has a better role, especially some patients who are not suitable for ACE inhibitors, such as severe renal failure, renal artery stenosis, elderly patients, etc.. Patients with coronary heart disease should be preferred to this class of drugs. In addition, there are diuretics, central adrenergic inhibitors, receptor blockers, etc., all of which should be used under the guidance of a doctor.
