How Dehydration Elevates Blood Glucose Levels
There is a direct physiological link between hydration and glycemic control. When your body experiences dehydration, blood volume contracts, causing the glucose in your bloodstream to become more concentrated (hyperglycemia). In turn, elevated glucose prompts osmotic diuresis—pulling more water into the urine and creating a vicious cycle of dehydration and spiking sugar numbers.
Furthermore, adequate water intake is essential for protecting the renal microvasculature and assisting the kidneys in safely clearing surplus circulating glucose and metabolic waste.
Aim for 2.5 to 3.5 liters of pure water daily (unless your doctor has placed you on strict fluid restrictions due to congestive heart failure or advanced chronic kidney disease).
