I go extremely tired after eating sugary sweets (without the high before hand, its just instant tiredness).
I'm tired all the time lately - I went into town yesterday and was ready to drop after being there for about two hours, which is extremely unusual as I can usually go through a full day of gallavanting around without even a thought of going to bed. I have to sleep when I get home from college, even on the days when I only have two lessons, and I wake up after about 10 hours sleep on the weekend and am ready to go back to bed a few hours after I've woken up.
I'm also thirsty a lot - I take bottled water with me when I go out to college or I can't make it through the day.
These things made me think of diabetes, but I'm only 17, I'm not overweight, I eat healthily, walk everywhere, and there's no history of diabetes in my family. I also haven't experienced any of the other symptoms, such as blurred vision or a change in weight. Is it possible that it is diabetes, or that I'm just rather tired and thirsty lately?
I thought it best to ask for a few opinions first before rushing to the doctors.
I doubt that your problem is diabetes. You can buy urine test strips from a chemist to see if you have too much sugar in your urine. Ask your doctor for a blood test, if you feel run down for a longer period. You maybe a little low on iron, either way a blood test will put your mind at rest.
