Hello. I have been extremely thirsty, urinate often, and feel like my blood sugar gets really low often throughout the day. However, some days are good. When I feel it is low I get shaky, feel weak, and just feel like something isn't right. I eat constantly...like every hour or so. I am in my thirties and am not overweight at all. I have not lost weight, but have to eat a lot to maintain my 117-120lbs. A year ago I had my blood work done and my sugar was 107 but after a few months it was 77. So, it was normal. I was not having the major symptoms like am now. Should I go and get checked for diabetes or no?
