Dietary Considerations for Interstitial Cystitis (IC)
Interstitial Cystitis (IC) is not well understood but the link between food and the occurrence of pain episodes is very clear. The list of foods that can irritate the bladder and thus cause pelvic pain in patients with IC is long. The important point is that not every food on the list will be an issue for every patient. As in the case of most situations, every person is unique and will respond differently to different foods. I tell patients to follow the Interstitial Cystitis (IC) diet in a strict fashion for two weeks. At that point evaluate their body’s response. If there is no change in your pain level, then diet may not have a significant impact in your case. However, most patients with IC will notice a change. Most patients with Interstitial Cystitis will notice a significant decrease in pain severity and episodes after following these diet rules. If this occurs then you have confirmation of the diet link to your pain.
What foods cause flare ups of Interstitial Cystitis (IC)?
Once you have established that there is a dietary component to your pain, the next step is figure out which foods are the culprits. At this point, I suggest adding one food item per week back to your diet. Start with the food that you miss the most. If your pain is exacerbated by this item, then you know that in your case this food item should be avoided. If you have no recurrence of pain, then this item is likely ok for you. Continue this process weekly until you have clearly established which foods you should avoid. The complete list follows.
Quick Synopsis: Foods to avoid for Interstitial Cystitis (IC)
A complete list of foods is included, but here is the short and sweet version. Avoid:
• Citrus fruits
• Tomatoes and tomato based sauces
• Carbonated and alcoholic beverages
• Spicy foods
Last tip: Prelief
If you just have to have something you know will cause a problem use “Prelief”. Prelief is an over the counter neutralizer that if taken 30 minutes before eating can help to decrease the occurrence of pain. I hope that this helps. Diet alone will not solve the problem and there is no known cure for Interstitial Cystitis. Diet along with the other therapies and interventions can offer significant relief to those suffering from the pain and bladder symptoms associated with Interstitial cystitis.
