Interstital Cystitis Diet


Many, (but not all) patients with Interstitial Cystitis (IC) find that modification of their diet can help control their symptoms and prevent flare ups. Also try smaller meals. To try the diet start on food in the Okay section, eliminating those in the avoid section. After a few weeks you can gradually reintroduce one by one those in the avoid section. If this does not result in a flare of your symptoms you can continue with that item and try adding in the next one. Symptom flares usually occur 2 to 24 hours after ingestion. You should be able to gradually work out which foods aggravate your symptoms. You may not have to give these up forever but find you can tolerate them in either small amounts or on a rotational basis. You may wish to consider working with a nutritionist.
