The root cause of easy thirst in diabetes is high blood sugar, and thirst is usually more likely to occur after meals, when glucose-lowering medications are not used properly, when it’s hot or you sweat a lot from exercise, or when you lose a lot of water from diarrhea. Typical symptoms of diabetes are excessive drinking, excessive eating, excessive urination, and weight loss. When blood sugar control is not satisfactory, the symptoms of thirst are more obvious, especially after meals, improper use of hypoglycemic drugs, heat or exercise sweating a lot, diarrhea lost a lot of water and other time periods, higher blood sugar or lower blood volume, more likely to produce thirst. Diabetic patients should be actively treated, drink more water, blood glucose control stabilization, easy thirst and other uncomfortable symptoms can be relieved.
