Why Does Drinking Alcohol or Consuming Sugar Make Us Thirsty?

We knew that exposure to alcohol or sugar turns on production of FGF21 in the liver. What we now show is that this hormone then travels in the blood to a specific part of the brain, the hypothalamus, to stimulate thirst, thereby preventing dehydration,” said Dr. Kliewer, Professor of Molecular Biology and Pharmacology and holder of the Diana K. and Richard C. Strauss Distinguished Chair in Developmental Biology. “Unexpectedly, FGF21 works through a new pathway that is independent of the classical renin-angiotensin-aldosterone thirst pathway in the kidneys.” https://www.technologynetworks.com/neuroscience/news/anti-dehydration-mechanism-discovered-299633?utm_campaign=Newsletter_TN_BreakingScienceNews&utm_source=hs_email&utm_medium=email&utm_content=62078379&_hsenc=p2ANqtz-8Q8Xo1QoNq0y2KeufdZiv2jh_452LQl8pER3779WJ0owv7ESO20xGBYg05mC45xizWWKtyz-XxGTjPAQGqGmuNaJRnUw&_hsmi=62078379
