#2 Increased thirst
There’s a fancy medical term for this symptom as well, and it’s called polydipsia. Normally the kidneys will absorb glucose in the bloodstream and recycle it, making it available to supply the body’s cells. When there is too much glucose in the bloodstream, the kidneys are not able to keep up with absorbing it and will simply discard it by excreting it in the urine. The increased urination that results can often cause dehydration and cause a person to feel thirsty.
