Diuretics increase the need to urinate, which can aggravate underlying urologic problems. The more caffeine you drink throughout the day, the more often you have to urinate. This may lead to dehydration and ill effects on the body as a result of dehydration.
CAFFEINE AND BPH
For men with benign prostatic hyperplasia (BPH), the contents within caffeinated beverages can have irritating effects. Men with BPH may already experience an overactive bladder, and caffeine may increase urinary urgency and frequency, potentially contributing to urinary incontinence. Caffeine can irritate the bladder, because it is a theoxanthine, a family of drugs that includes elements found in chocolate and teas.
CAFFEINE AND ERECTILE DYSFUNCTION
Erectile dysfunction, or the inability to achieve or keep an erection, plagues between ten and twenty million men in the United States alone. While erectile dysfunction can be caused by more serious issues, like cardiovascular disease, it can also be caused by consuming too much caffeine. Nervousness or increased adrenaline release inhibits erections. While Americans spend millions on medication intended to help them achieve an erection, for some, the problem can be solved by changing a few dietary habits, like consuming too much caffeine.
CAFFEINE AND BED-WETTING
In children, bed-wetting past the normal age can be caused by drinking or consuming too much caffeine. As previously stated, caffeine increases the frequency of urination and may contribute to a child wetting the bed or not being able to make it to the restroom in time. If your child wets the bed or wets themselves throughout the day, cutting out caffeine from their diet may help.
