Blood sugar control is good, why are there complications?

Many people with diabetes will ask: “I have a good blood sugar control, how can I still have diabetic eye disease?” Many people have started to question the diabetes experts’ control of blood sugar treatment for diabetes because of similar problems. In fact, treating diabetes to control blood sugar is really the key.

In fact, just controlling blood sugar is not enough. Only by controlling all kinds of risk factors in an all-round way can we reduce the occurrence of chronic complications of diabetes. Complications may occur in the following areas:

Focusing solely on glycemic control, neglecting comprehensive interventions for cardiovascular risk factors: Studies have revealed that macrovascular complications of diabetes (mainly referred to as heart, brain and lower extremity blood vessels) are the result of a combination of risk factors. Therefore, to prevent macrovascular complications, it is not enough to control blood sugar only. It is also necessary to control blood pressure, blood lipids, blood viscosity and body weight at the same time, and strictly meet the control standards.

As early as the pre-diabetes, macrovascular complications may have existed: the study found that macrovascular complications are early in the pre-diabetes, with the onset of insulin resistance may have begun, not all after the onset of diabetes. Therefore, it is currently emphasized that active intervention should be carried out for people at high risk of pre-diabetes. This is not only to reduce the incidence of diabetes, but also to prevent cardiovascular complications.

Strict control of blood sugar, complications are only significantly reduced, but not equal to no: two major studies in the field of international diabetes – diabetes control and complication trials and UK prospective diabetes studies confirmed: strict control of blood glucose can make diabetic microvascular complications (ie kidney Retinal and neurological complications) are reduced by approximately 2/3, and there is a certain reduction in macrovascular complications.

However, “reduction” does not mean “no”, so some patients, although blood sugar control is better, it is not difficult to understand coronary heart disease (macrovascular complications). However, it is imperative to relax the strict control of blood sugar because it cannot prevent the occurrence of complications 100%. After all, strict control of blood sugar is the basic work to prevent complications, and the effect is quite remarkable.
