Could i have nerve damage or diabetes from carpal tunnel?

Yes and No: Yes carpal tunnel syndrome is damage to the median nerve at the wrist due to compression. No carpal tunnel would not cause diabetes.

Carpal tunnel: You do not get diabetes from carpal tunnel nerve entrapment. Depending on how severe the nerve is entrapped you can get from mild to severe nerve damage. An evaluation by a neurologist and a test called an EMG can help assess how severe the nerve damage is.

Carpal tunnel: Carpal tunnel syndrome is characterized by hand pain and recurrent numbness or "pins and needle" sensations in the thumb, index, middle finger and the lateral aspect of the ring finger. It may be triggered by repetitive use, like driving or keyboard typing. Diabetes or obesity increases risk of onset. Wearing a wrist cock- up splint is very effective. Surgery reserved for severe cases.

Nerve damage: Carpal tunnel syndrome may cause nerve damage to the median nerve, which runs through the center of your wrist. Diabetes may also cause nerve damage, although it typically affects nerves in the legs and feet. Carpal tunnel syndrome does not cause diabetes of course.
