7. Increased Thirst
Increased thirst, especially after a meal, can signal prediabetes. Your body has begun to work very hard to eliminate excess glucose from the bloodstream, and one of the ways it does this is by diluting the blood and flushing unprocessed sugar out via urine. To get that water, your body will often pull it from surrounding cells, leaving them dehydrated and you chronically thirsty.
When you are locked in this vicious cycle, you may experience dehydration no matter how much you drink. However, there is some evidence that staying properly hydrated on a daily basis can help prevent the development of prediabetes and eventually, type 2 diabetes. Water and blood sugar regulation go hand in hand.
