Which symptom is a sign of neuropathy in diabetic patients?

Decreased sensation is a hallmark symptom of neuropathy, particularly in diabetic patients. Neuropathy is a type of nerve damage that often occurs in people with diabetes, leading to a loss of feeling in the extremities, especially the feet. This loss of sensation can make it difficult for individuals to feel pain, temperature changes, or even minor injuries, which can lead to further complications such as ulcers or infections.

In contrast, dermatitis refers to skin inflammation, which is not specifically linked to neuropathy but may arise from other dermatological issues. Calluses are raised and hardened areas of skin that develop due to pressure or friction, often due to foot deformities or improper footwear, rather than nerve damage. Foot swelling, while common in various conditions, does not directly indicate neuropathy. Thus, decreased sensation is the most accurate indicator of neuropathy among these choices.
