One Major Side Effect Coffee Has on Your Bladder, Says Science

Coffee is one of the world’s most popular beverages. People use it as a morning or mid-afternoon pick-me-up, enjoy sipping it with friends in a cafe, and may even enjoy a cup after dinner. And while coffee is delicious and contains many health benefits, it can sometimes have negative effects on different parts of our bodies.

For example, some individuals have reported that caffeinated coffee affects their bladder. In fact, one of the side effects of coffee on the bladder is an increase in urination frequency. This is because caffeine can alter bladder function, which can affect both the frequency and volume of urination.

Caffeine is known to increase bladder activity, so it may be prudent to limit your daily coffee intake, particularly if you already experience bladder discomfort or other related issues.
According to a study published in The Journal of Urology Annals, consuming as little as 4.5 grammes of caffeine can induce “early urgency” and increase the frequency with which you must urinate. Participants aged 18 to 40 who reported symptoms of Overactive Bladder Syndrome were evaluated for this study.

In addition, the participants reported that they consumed coffee frequently, defined as more than three cups per week. They gave the group eight millilitres of water without caffeine first, and then eight millilitres of water with caffeine in a separate session.

Another study published in the International Urogynecology Journal found that consuming more than 204 milligrammes of caffeine per day was associated with urinary incontinence.

Caffeine is known as a diuretic because it increases the activity of the bladder and the frequency of urination, as demonstrated by these research findings. Other typical diuretics include green tea, black tea, and alcohol.

If you have bladder problems or if you urinate more frequently than you believe is normal, you may want to discuss the potential causes with your doctor. Reducing your caffeine intake, particularly from caffeinated coffee, may help you control your urination.
