Can high blood sugar cause itchy hands? i dont have diabetes but i just noticed the last two days that when i eat a little too much junk food my palms & my fingers itch like crazy. this has never happened before?

This may be an indication of neuropathy due to poor control of blood sugar. It is imperative that see a doctor to control your blood sugar better. If you have measured A1c, that should be below 7 for evidence of good control. Try taking multivitamins with B12, even if that helps, it would not be a substitute for proper glucose control. Blood glucose control is essential to prevent complications.

Poorly controlled diabetes can be related to fungal infections on the hands which can cause itching. Show to your Dr.
