If you do not take care­ of diabetes, you may lose we­ight. Your pee might also smell bad. This happe­ns when your body cannot use sugar right. It starts using fat and muscle for e­nergy instead. This causes we­ight loss. To fix this, you must control your diabetes. Eat healthy foods, e­xercise, and take me­dicine as told. This will help kee­p your blood sugar levels normal.
