Hi im a 29 year old guy not over weight! I went to the docs about a month ago for a blood test as i was ill! The doc told me i possibly have an overactive thyroid problem! I then received a letter saying my glucose level was higher than normal and they now want me to go back for a fasting blood test this coming wednesday! In the mean time i have felt terrible, i am dizzy, cant breath, feel sick and have a dull headache! i would like some advice on the symptoms that diabetics here experienced before diagnosed and if i should seek medical attention earlier than wednesday because i dont think i can go on much longer with these symptoms! Thanks
