Does Caffeine Really Dehydrate?

The Doctors invite on otolaryngologist and author of “Hype” Dr. Nina Shapiro to set the record straight on three common health beliefs.

Can caffeine make you dehydrated? The Doctors asked their viewers and of the 35,000 who weighed in, 76% think this is a reality. Yet, it’s not. Dr. Shapiro says caffeine-containing products have fluid in them, so even if there is a diuretic effect, the amount of liquid offsets the amount you pee out, so it’s not really dehydrating. “You make a good point, coffee has a ton of water in it!” plastic surgeon Dr. Andrew Ordon notes!
