Excessive Thirst

Correcting a low-potassium/high-sodium ratio will directly reduce thirst. Diabetes, pre-diabetes, or insulin resistance is the most common driver of pathological thirst. Reducing dietary carbohydrates lowers blood glucose and reduces thirst driven by glucose dysregulation in insulin-resistant individuals. Many people drink water out of habit rather than genuine thirst, which can cause electrolyte problems. The foundational hydration recommendation is to drink only when thirsty, not on a fixed schedule.
