Hi. For a while now (at least a 2 years probably longer) I've been having some odd symptoms and I've just been wondering if they can be symptoms of diabetes. One of the most concerning to me is visual abnormalities. For example earlier on today I was walking through town feeling a bit off. A sort of hard to explain feeling of almost feeling like I'd had a burst of energy but not in a good way. It made me feel sickly and unwell. This was followed a few minutes later by coloured spots infront of my eyes. Very similar to when you look into a strong light in the dark and the colours have burned into your eyes but stronger and slight dizziness. Along with the strange sort of energetic feeling. I had just eaten a subway. I often get these symptoms. Along with others. For example some days needing to urinate frequently (at least once an hour, occasionally more often than that) and sometimes feeling unwell in a way I can't quite put my finger on. Lately I have been eating an unusual amount of sugar (stuff leftover from Christmas that I want to eat before I start a diet) I'm a 32 year old male approx 11st . I'm very active now and have slashed the amount of sugar in my diet compared to 6 years years ago when I was 17 stone and used to live off cola and lucozade and sugary junk. I worry that although I'm alot healthier now maybe my rediculous eating habits when I was younger could have done some lasting damage. Thanks for any advice.
