In brief: Too much insulin?
A doctor will need to see your skin problem to confirm this, but your description sounds like acanthosis nigricans.
This usually means your body is not responding well to insulin, and may be diabetic or pre-diabetic. Losing weight can help this skin condition, and reduce your chances of developing diabetes, or at least postpone it.
