Diagnosing diabetic neuropathy often involves a combination of clinical and diagnostic tests. Physical exams, including testing reflexes and sensory responses, are commonly used. Additionally, nerve conduction studies and electromyography can help confirm the diagnosis by measuring electrical activity in the nerves and muscles.

Testing for diabetic neuropathy is generally straightforward and non-invasive. During a nerve conduction study, small electrodes are placed on the skin to measure nerve signals. Electromyography involves inserting a thin needle into the muscle to record electrical activity. The results can help determine the extent of nerve damage and guide treatment decisions.

Accurate diagnosis is essential for effective management of diabetic neuropathy.
