Q. When I read your article about irritable bladder, I didn’t see any mention of coffee ingestion. I used to drink two large cups of very strong coffee every morning. Then I came down with bladder irritation, and now I can’t drink coffee at all.

A. Many people with this condition, also known as bladder pain syndrome or interstitial cystitis, have trouble with acidic beverages such as citrus juices, coffee, tea or carbonated beverages (BJU International, June 2012).

On the other hand, they might find that their symptoms improve when they take sodium bicarbonate (baking soda) or calcium glycerophosphate (Prelief). These compounds can help neutralize acid in food.
