Drinking plenty of water and other beverages throughout the day and even overnight is also a glaring symptom of diabetes. Intake of fluids can be something like 1 gallon (approximately 4 liters) or more per day in a pre-diabetic person. Another problem is that you won’t feel hydrated and refreshing immediately after drinking a fluid, a thing that urges you to drink more and more fluids. The more you drink, the more you pee!
The reason behind this: The kidneys activate the thirst center in the brain due to excess excretion of fluids and electrolytes through urine. The more you urinate, the more your body requires water to carry out normal functions in the body.
