1. Polydipsia (Excessive Thirst)
This is the telltale sign of high blood sugar and if you feel like your thirst mechanism has increased dramatically, then consider getting checked out. Polydipsia is the medical term for increased thirst and the increased thirst mechanism is something that you will recognize. If you have been working out a lot, working outdoors, sweating, or you ate a meal with a good amount of sodium, then do not get too worked up. It is normal to be excessively thirsty following these reasons, but make sure to monitor your thirst over the next week to ensure the cause.
