Which symptom is typical of diabetic peripheral neuropathy?

• A. Reduced ability to feel pain or temperature in the extremities
• B. Frequent UTIs or incontinence
• C. Muscle weakness and difficulty walking
• D. Problems with erectile dysfunction

Answer: (A)

The key idea here is that diabetic peripheral neuropathy most often first damages the sensory nerves in the feet and hands, leading to a reduced ability to sense pain or temperature in the extremities. This loss of protective sensation means people may not notice minor injuries or burns, which can then escalate into ulcers if not checked—an important clue in understanding the condition.

While diabetes can cause other problems, such as autonomic issues affecting bladder or sexual function, those are not the hallmark feature of diabetic peripheral neuropathy. They can occur but typically reflect different nerve fiber involvement or later stages, whereas diminished sensory perception in the distal limbs is the classic and most typical symptom.
