2. Frequent Urination
Along with thirst comes urination, or one of the body’s ways of eliminating excess fluid. When your blood sugar is high, a tell-tale sign is frequent urination and part of that comes due to the thirst mechanism. With increased fluids comes the need to urinate more frequently and generally these two signs come together. Be aware that not all frequent urination means high blood sugar, as caffeine and diuretic drugs can cause increased urination when consumed.
