Coffee causes “leaky bladder” in men
A study published in the Journal of Urology found that men who drink about two cups of coffee each day are more likely to have urinary incontinence (UI) than men who do not drink coffee at all.
A national survey of about 5,000 American men, age 20 and over, found that men who consumed about 234 milligrams of caffeine each day were 72 percent more likely to have moderate to severe UI (aka: a ‘leaky bladder’) and men who consumed 392 milligrams of coffee each day were twice as likely to have UI. Two cups of coffee has about 250 milligrams of caffeine – enough to cause at least moderate UI.
The men’s total water intake had no impact on their risk of incontinence, meaning that it is the caffeine in the coffee that causes UI not the liquid itself.
The link between UI in women and caffeine is already well established. This is one of the first studies to find a similar link to incontinence in men.
