What causes the microvascular complications seen in diabetes mellitus

The chronic complications are mainly the result of longstanding damage to blood vessels. These complications are grouped as microvascular due to basement membrane thickening or macrovascular due to accelerated atherosclerosis. The major microvascular complications are diabetic retinopathy, nephropathy, and neuropathy.

What causes microvascular complications in patients with diabetes mellitus?

High glucose levels increase the flux of sugar molecules through the polyol pathway, which causes sorbitol accumulation in cells. Osmotic stress from sorbitol accumulation has been postulated as an underlying mechanism in the development of diabetic microvascular complications, including diabetic retinopathy.

What causes the chronic microvascular and macrovascular complications of diabetes mellitus?

The chronic complications are mainly the result of longstanding damage to blood vessels. These complications are grouped as microvascular due to basement membrane thickening or macrovascular due to accelerated atherosclerosis. The major microvascular complications are diabetic retinopathy, nephropathy, and neuropathy.

Atherosclerosis is the main reason for impaired life expectancy in patients with diabetes whereas diabetic nephropathy and retinopathy are the largest contributors to end-stage renal disease and blindness, respectively.

How can you prevent microvascular complications from diabetes?

Diabetic microvascular complications can be controlled with tight glycemic therapy, dyslipidemia management and blood pressure control along with renal function monitoring, lifestyle changes, including smoking cessation and low-protein diet.

The most common early complication of diabetes, related to insulin treatment, is hypoglycemia. Mild hypoglycemic reactions, consisting of headache, tremors, abdominal pain, or mood changes, are considered a part of tight control.

What are the microvascular complications of hypertension?

Hypertension also seems to accelerate the development and progression of microvascular complications (nephropathy, neuropathy and retinopathy) of T2DM.

Why do microvascular complications occur?

Microvascular disease tends to occur predominantly in tissues where glucose uptake is independent of insulin activity (eg kidney, retina and vascular endothelium) because these tissues are exposed to glucose levels that correlate very closely with blood glucose levels.

What are three questions you should ask your diabetic patients to prevent microvascular complications?

• When was the patient’s last dilated eye examination? What were the results?
• Does the patient have known kidney disease?
• What were the dates and results of the last measurements of urine protein and serum creatinine levels?

What is a risk factor associated with macrovascular complications of diabetes mellitus?

For macrovascular complications, the most important factors were in men, age (OR 1.09, p < 0.001) and hypertension (OR 4.85, p < 0.001) and in women, age (OR 1.08, p < 0.001) and duration of diabetes (OR 1.08, p < 0.01).
