Diabetic neuropathy results when constant high blood glucose levels damages nerve structure and function. This can affect any part of the body, so the symptoms can range from numbness in the fingers and feet to urinary problems.
Diabetic neuropathy is divided into 4 main types:
Peripheral neuropathy: The most common form of diabetic neuropathy, the peripheral nerves, such as those in the feets, leg, hands and arm, are affected, causing tingling, pain and numbness.
Autonomic neuropathy: This refers to an infection in the nerves of the digestive and urinary systems, among other visceral systems.
Proximal neuropathy: Here, the nerves in the lower part of the body such as the thighs, hips, buttocks or legs are affected.
Focal neuropathy: In this type, only specific nerves are affected, leading to defects within that nerve distribution.
