The relationship between diet and IC/PBS can be a confusing issue for sufferers. On the one hand, you are advised about the importance of a healthy diet and to eat a variety of foods from different food groups. This is certainly good advice. On the other hand, some of these “healthy” foods can make your symptoms worse. So, where do you start?

Unfortunately there are no hard and fast rules. Every person has different tolerances to foods that will irritate their bladder.  The amount of food consumed before bladder irritation starts can also vary from one person to another.  Some people may be able to comsume a small quantity of an “offending food,” but if they consume more, they may have an IC flare; in others, just one mouthful of the same “offending food” may make their symptoms much worse.

Others may find that their diet does not seem to influence their IC symptoms at all. It is not fully understood why there are such individual responses to diet; perhaps it is because IC/PBS sufferers have different causative factors for their bladder symptoms, giving different experiences with food.

Possible Trigger Foods For IC/PBS Sufferers

There is no definitive or exhaustive list that is correct. In our experience, based on information given by our membership, every individual is different and what may suit one person, may not suit another. However, there are certain “bad” foods that everyone seems to agree on shown below:

Caffeinated Tea and Coffee (decaffeinated may be tolerated)
Carbonated Drinks
Acidic Fruit Juices (other than blueberry or pear)
Spicy Foods
Chocolate (contains caffeine)
Fruit – particularly berry fruits i.e. strawberries

Generally, all foods high in acidity are not well tolerated. COB can offer a nutrition advice service to our members, whereby they can speak with an expert to help them cope with diet queries and problems.  We also have a comprehensive diet sheet which is available to members.

Dietary Supplements

Here are a few alternative supplements which may aid recovery: 

L-Arginine – A naturally-occurring amino acid thought to increase the blood flow to the bladder. 

Quercetin – A bioflavonoid, it is a natural anti-histamine. 

Bromalaine – It is derived from the pineapple plant and is believed to have anti-inflammatory properties. 

Pumpkin Seeds – They are high in Omega-3 essential fatty acids which are powerful anti-inflammatory agents. The seeds of the pumpkin were used by American Indians to treat bladder, kidney and digestive problems. 

Prelief® – This product is a calcium glycerophosphate, a food-grade mineral classified as a dietary supplement, for use with acidic foods and beverages, it acts as an alkalising agent to enable some with IC/PBS to tolerate certain foods that may cause irritation. Prelief® comes in two forms, powder or tablets. It is available from Amazon or from the COB Shop – click here –Welcome to the COB Shop  The COB Foundation conducted a Prelief® trial in 1998, for trial results please contact us(only available for members).
