4. Urination
In full-blown diabetes, frequent urination is one of the most obvious symptoms and something that many people notice first. This is considerably less likely for those with prediabetes but you are still likely to notice your frequency increasing ever so slightly.
If you find yourself going to the toilet more frequently, or find that you make more urine each time you go, then this might be a sign that you are suffering from diabetes or that you simply have too much sugar in your bloodstream that your body is trying to eliminate.
