Need a little more info really. Have you been diagnosed T1, T2 ? Are you on insulin, meds ? Are you testing your blood etc ? Don't want to appear unhelpful but it's difficult to answer anything just on your brief post. Seeing as you're here, I'll take a stab in the dark and say you may have diabetes ? To start with, try to reduce your intake of carbs and exercise if you can. Good luck.
