Complications Of Diabetes Mellitus

Diabetes mellitus (DM), both type 1 and type 2, affects many organ systems, particularly the heart, eyes, kidneys, and the peripheral and autonomic nervous systems.

• Cardiovascular Disease: Diabetes significantly increases the risk of cardiovascular problems, including heart disease, stroke, and peripheral arterial disease. High blood sugar levels, along with other risk factors like high blood pressure and abnormal lipid profiles, contribute to these complications.
• Kidney Disease (Diabetic Nephropathy): Diabetes is a leading cause of kidney failure. Over time, high blood sugar levels can damage the small blood vessels in the kidneys, leading to impaired kidney function.
• Eye Complications (Diabetic Retinopathy): Diabetes can damage the blood vessels in the retina, leading to diabetic retinopathy, which is a leading cause of blindness in adults. It can also increase the risk of cataracts and glaucoma.
• Neuropathy: Diabetes can cause nerve damage (neuropathy), leading to symptoms such as tingling, numbness, pain, and weakness, particularly in the extremities. This can affect various nerves, including those in the feet and hands.
• Foot Complications: Poor circulation and neuropathy can contribute to foot problems, including infections, ulcers, and, in severe cases, amputations.
• Skin Conditions: People with diabetes may be more prone to skin infections and conditions, including bacterial and fungal infections.
• Hearing Loss: There is an association between diabetes and an increased risk of hearing loss.

Both lifestyle (especially nutrition) and medical interventions play important roles in prevention and treatment of diabetes complications. Control of weight, blood glucose, lipids, and blood pressure is essential. In addition, dietary steps to limit advanced glycation end products (AGEs) are also important. AGEs are toxic compounds formed when glucose interacts with proteins and are a major contributor to macrovascular and microvascular complications.
