Polyphagia (increased or excessive hunger) is a sign of diabetes, but fatigue is not usually associated with diabetes. Diabetes has a constellation of symptoms including increased urination, increased thirst, and increased hunger.

There are a lot of causes for numbness in feet other than diabetes mellitus. It can be related to nerve impingement, or simply positional compression of a nerve serving this area. With any concerns for diabetes, please consult your medical provider or PCP to get tested.

Expert Answer

The cause of type 2 diabetes mellitus is related to an impaired insulin release and insulin resistance by the pancreas. When one's blood sugar remains high, this itself can further worsen pancreatic function and cause additional resistance.
