Which means individuals who reported consuming lower than half a liter of water per day have been extra vulnerable to elevated blood sugar than individuals who reported greater than 1 liter.
Scientists theorize that dehydration can result in a rise within the hormone vasopressin, which prompts the kidneys to retain water and the liver to provide blood sugar, doubtlessly affecting the physique’s skill to control insulin over time. (One paper, nevertheless, famous that there’s inadequate proof linking varied well being situations with dehydration, together with sort 2 diabetes.
