The effects of diabetes manifest in nearly all organ systems of the body. If left untreated, diabetes can lead to heart disease, kidney failure, loss of vision, loss of foot etc. But what is cause of these effects of diabetes?
As you know, diabetics have higher blood glucose levels than do normal people. The excess blood sugar gets deposited in blood vessels of diabetics, which leads to two sets of complications both related to abnormalities in blood vessel
These complications are due to abnormalities in small blood vessels. They are:
These are due to abnormalities in bigger blood vessels including those supplying the heart. These include, Ischemic Heart Disease (IHD or CHD), Carotid Artery Disease (CAD), Peripheral Artery disease (PAD) and their complications such as MI or heart attack, stroke, gangrene of legs etc.
CVD is the leading cause of death in diabetics and diabetes is considered to confer ‘very high risk’ for heart disease
Many studies have looked into the effect of good control of blood sugar levels on these complications in type 1 and type 2 diabetes. Some of these are
The results of these studies are summarized below:
Tight control of blood sugar (HbA1c levels less than 7% and less than 6.5%, if possible) results in lesser microvascular complications in all diabetics. For CVD risk reduction, tight control in the initial years of diabetes is most beneficial
To know more about what does tight control actually mean, read ‘What does good control of blood sugar mean in diabetes?’
Also, diabetes experts recommend frequent monitoring of diabetic patients by blood tests and physical examination to detect and treat early the complications of diabetes as well as to ensure good control, get the complete list of routine tests for diabetics
