i would say the medication you are on is your problem, as for the blood sugar level you could get a blood test done just to rule it out , the healthy adults blood sugar level is between 2 and 7 you would only be higher then 7 if your body was making too much sugar or lower then 2 if not making enough. peeing to much is only one sympton of being diabetic although many people have no symptons and do not realise there is a problem, weight does not need to be a factor either although it wont help. get to a doctor and get yourself tested , if you are a possible diabetic then leaving it will only cause long term damage.
