Lately, I have felt thirsty more than usual, and sometimes feels like I have blood sugar drops where I get weak and hungry. I am only about 30 lbs overweight, and 30 years old. Does it sound like I'm developing diabetes to you. My doctor checked by blood sugar the other day but that was it, is that enough to tell If I'm going to get, or have, diabetes, and does it sound like I do to you?
