Diabetic Neuropathy: The Nerve Damage Diabetes Canβt Be Ignored
Diabetic neuropathy is a common complication of diabetes caused by prolonged exposure to elevated blood glucose levels, leading to damage of nerves and their blood supply. It most commonly affects the feet and legs, but can also involve the hands, digestive system, cardiovascular system, bladder, and sexual function.
Key types:
β’ Peripheral neuropathy: numbness, tingling, burning or shooting pain, weakness, and loss of protective sensation, especially in the feet.
β’ Autonomic neuropathy: may cause digestive problems, bladder dysfunction, abnormal sweating, orthostatic blood pressure changes, and sexual dysfunction.
β’ Proximal neuropathy: affects the hip, buttock, or thigh and may cause significant pain, weakness, and weight loss.
β’ Focal neuropathy: affects a specific nerve and can cause localized pain, weakness, or sensory changes.
Important nursing point: Loss of protective sensation is particularly dangerous because a patient may not notice a cut, blister, burn, or pressure injury. This can progress to a diabetic foot ulcer, infection, gangrene, and, in severe cases, amputation.
Assessment may include neurological examination, 10-g monofilament testing, vibration testing, foot examination, and selected laboratory investigations. Nerve conduction studies are used when clinically indicated, particularly in atypical presentations.
Management focuses on individualized glycemic control, cardiovascular risk-factor management, regular foot inspection, appropriate footwear, physical activity, treatment of neuropathic pain when present, and identification of other causes of neuropathy such as vitamin B12 deficiency.
Remember: Early recognition + good diabetes control + proper foot care can significantly reduce complications and improve quality of life.
