Interstitial cystitis, also known as IC, is a condition that affects the bladder and urinary tract. It causes painful burning upon urination, bladder pain, feelings of fullness and painful intercourse. It feels much like a urinary tract infection, though urine cultures always come back negative for any kind of bacteria or infection. Though the exact causes of IC are unknown, it is believed by many who suffer from this condition that certain foods exacerbate the symptoms and should be avoided.
Alcohol
Alcohol irritates the bladder. It is also acidic and can make a sensitive bladder wall or urinary tract inflamed. Even if you suffer from urinary pain all the time, drinking an alcoholic beverage will only work to make your symptoms worse.
Coffee
Many people start their day with a cup of coffee, but doing so could contribute to the suffering you encounter due to interstitial cystitis. Coffee is acidic and contains caffeine, which is a well-known bladder irritant, and is best avoided to keep your IC symptoms at bay.
Soda
Caffeinated sodas (most brown colas) should be avoided as well. Many sodas contain citrus ingredients, which are acidic, even if they are of the caffeine-free variety. Moreover, carbonation has even been linked to bladder irritation.
Chocolate
Chocolate is a tasty treat for many, but its acidic content and trace amounts of caffeine do more harm to your bladder than help ease your IC symptoms.
Citrus Fruits
Many kinds of fruits, especially citrus ones, irritate the bladder's lining and produce uncomfortable or even painful symptoms of your interstitial cystitis. Eat citrus only in moderation or eliminate it altogether if you notice a direct correlation between your morning orange juice and painful urination.
Spicy Foods
Spicy foods are pleasing to the palate, but they may make your IC seriously flare up. Foods seasoned in styles like Cajun, jerk or Indian or that contain hot peppers, are best avoided to keep your symptoms to a minimum.
