Diabetes complications can affect nearly every organ in the body if blood glucose remains uncontrolled for long periods. Chronic hyperglycemia damages blood vessels and nerves, leading to both microvascular and macrovascular complications.
🧠 Brain: Diabetes significantly increases the risk of cerebrovascular disease and stroke due to accelerated atherosclerosis.
👁 Eyes: Long-term diabetes can cause diabetic retinopathy, macular oedema, cataracts, and glaucoma, which may eventually lead to vision loss if untreated.
❤️ Heart: Patients with diabetes have a much higher risk of coronary artery disease, myocardial infarction, and heart failure.
🦷 Teeth and gums: High glucose levels promote bacterial growth leading to gingivitis, periodontitis, and tooth decay.
🧠 Nerves: Diabetic neuropathy is very common and may present as numbness, burning pain, or autonomic dysfunction affecting organs like the gut and bladder.
🩺 Kidneys: Diabetic nephropathy is one of the leading causes of chronic kidney disease and dialysis worldwide.
🦶 Wound healing: Poor circulation and nerve damage can cause slow wound healing, especially in the feet, increasing the risk of ulcers and infections.
⚠️ Key concept: Tight glycemic control, blood pressure control, lipid management, and regular screening are essential to prevent these complications.
