Diabetes combined with hypertension is very common, three high, four high, five high in the most common hypertension and hyperglycemia, these two together will increase the emergence of diabetes complications, especially macrovascular, small vessel complications, such as cardiovascular and cerebrovascular complications or diabetes nephropathy, treatment is as follows: 1, daily monitoring of blood glucose and blood pressure, until blood glucose and blood pressure stable, can reduce the number of monitoring; 2, active control of blood glucose and blood pressure, using effective glucose-lowering drugs and antihypertensive drugs, and being able to adhere to continuous treatment. If diabetes and hypertension exist at the same time, glucose-lowering drugs and antihypertensive drugs are appropriately selected. If there is no diabetes but only hypertension, there are more types of antihypertensive drugs to choose and the preferred direction is different. But the first choice of drugs when the two are combined, antihypertensive drugs preferred ACEI or ARB class, that is, Pulley class or Satan class, this type of antihypertensive drugs in addition to lowering the blood pressure of diabetic patients, but also can improve the kidney function and heart function of diabetic patients, have a protective effect on the kidney and heart, so in the case of both elevated blood sugar and blood pressure need to lower sugar and lower blood pressure, the first choice of the five major types of antihypertensive drugs and no diabetes choose of antihypertensive drugs are not the same.
