THE FACTS
There are many reasons to stay properly hydrated, but only recently have scientists begun to consider diabetes prevention one of them. The amount of water you drink can play a role in how your body regulates blood sugar, researchers have found.
The reason: a hormone called vasopressin, which helps regulate water retention.
When the body is dehydrated, vasopressin levels rise, prompting the kidneys to hold onto water. At the same time, the hormone pushes the liver to produce blood sugar, which over time may strain the ability to produce or respond to insulin.
One of the largest studies to look at the consequences was published last year in Diabetes Care, a publication of the American Diabetes Association.
