How Drinking Soda Can Affect Your Bladder Health
Carbonated beverages may not be the best choice if you struggle with frequent bladder infections or irritation.

Common Bladder Irritants in Soda
“Caffeine is probably the most common and worst offender,” says Lamia Gabal, MD, a urologist in Tustin, California. “It’s a diuretic, so it causes your body to make more urine. Caffeine is also a bladder stimulant, so it makes your bladder squeeze more strongly and at smaller volumes.”
Seltzer Water and Bladder Health
Alicia Jeffrey-Thomas, DPT, CLT, a Boston-based pelvic floor physical therapist, says the carbonation in seltzer water and sodas is also a bladder irritant that can contribute to both urination urgency and frequency. She recommends keeping your consumption of seltzer water (and other non-water beverages) to just 25 percent of your daily fluid intake for optimal bladder health.
Urologists also advise against sipping seltzer like water all day.
The problem is seltzer’s carbon dioxide content, according to Austin DeRosa, MD, a urologist and urologic oncologist with UCHealth Cancer Center – Highlands Ranch in Colorado. “The carbon dioxide in sparkling water tends to irritate the lining of the bladder,” he says. “Carbonated beverages don’t cause damage to your bladder per se, but they can cause an exacerbation of underlying bladder symptoms.” So chugging sparkling water in place of regular water could result in bladder pain and increased urination urgency and frequency, especially for anyone who already has a sensitive, irritated bladder or urgency symptoms.
If you think your love of seltzer could be impacting your bladder health, Dr. Gabal says to remove it and other common bladder irritants from your diet. “Then add things back slowly, one at a time, to determine if your bladder is sensitive to these things,” she says.
If you can’t go a day without seltzer water, just make sure you’re not drinking it all day long. Dr. DeRosa says if you’re getting 2 to 3 liters of fluid (preferably water) per day, drinking a little seltzer water shouldn’t be too problematic.
If you deal with bladder irritation on a regular basis, consult your primary care doctor or urologist for help. With their assistance, you can address the underlying issue while still likely enjoying your favorite foods and drinks in the process.
