2. Dark spots on the skin:
Acanthosis nigricans is a skin condition that presents as dark patches of skin with a velvety texture. They usually appear in areas where the skin folds or stretches most often: on the neck, armpits, groin, elbows, behind the knees, and on the joints of the fingers.
Although this condition can affect otherwise healthy people, it is a common sign of prediabetes or diabetes and should be checked out by your doctor.
3. More appetite:
Excessive appetite (polyphagia), along with the increased thirst and urination mentioned above, are the 3 main signs of diabetes. If your body doesn’t produce enough (or any) insulin or respond to it normally, it can’t convert food into the glucose your cells use for energy. And this causes greater hunger that does not go away after eating. In fact, eating only makes your blood sugar rise even more.
