Going to the bathroom a lot? 

Urinating more then usual is one of the first signs to look for. The reason why you’re going to the bathroom more is because your blood sugar levels are too high and your body is looking for a way to get rid of the excess sugar. And the main way for your body to get rid of the sugar is through your urine. And the more you urinate the more your body gets dehydrated, causing you to drink even more. And the vicious cycle continues.
