3. Excessive Thirst
Excessive thirst is one of the telltale signs of high blood sugar. In fact, if you have excessive thirst, excessive urination, and excessive hunger, then you have all three of the major signs of prediabetes and diabetes. If you just go to the bathroom a lot and are always hungry and thirsty, it doesn’t mean you have diabetes, but it is something to look into. There are a lot of conditions that cause excessive thirst.
You might have a cold, the flu, vomiting, and diarrhea-related dehydration, dehydration from strenuous exercise or hot weather, or even allergies. Plus, excessive thirst from diabetes can happen so slowly that you don’t notice it. Basically, when too much glucose builds up in the blood, your kidneys have to work extra hard and expel it.
They will try as hard as they can to dispense with that excess glucose, and that means you’ll have frequent urination. Frequent urination will lead to excessive thirst. You’ll be dehydrated and need to drink water more frequently.
