How Diet Might Trigger IC Flares
There are many theories as to why certain foods and beverages may trigger interstitial cystitis (IC) symptoms. Researchers are continuing to learn more about the underlying causes. There may be several factors leading to the sensitivity of substances found in food items. Here are the four leading theories on why what you eat might bother your IC:
Irritate the Bladder Wall
One theory thought to be a cause of IC symptoms is that a layer of the bladder wall is damaged. This area of the bladder may allow substances found in the urine to seep into the sensitive layers of tissue which make up the bladder wall. When urine that contains these substances hits these parts of the bladder, they become irritated. This irritation will cause a person with IC feel pain and discomfort after eating bothersome foods and beverages.
Other scientists propose that IC may relate to a problem with the nervous system. Substances in certain foods and beverages may excite sensitive nerve endings found in the bladder. This may result in bladder symptoms.
Provoke Increased Nerve Sensitivity
People with IC appear to have higher levels of pain receptors that are sensitive to certain compounds in foods. For example, they may have more capsaicin receptors. Capsaicin is the substance found in peppers. The more capsaicin a pepper contains, the hotter it is! Bell peppers contain very small amounts of this substance. They usually do not flare IC symptoms. However, the peppers often used in Thai and Mexican dishes, contain higher amounts of capsaicin and these dishes may cause IC flares.
Provoke Organ Cross Talk
Researchers have also proposed that IC bladder pain may actually be due to pain in the large intestines that are in the same area of the body as the bladder. The scientists who suggested this theory dubbed it the “pepperoni pizza” hypothesis. Why? Because, eating a slice of pizza with this spicy meat may hit the stomach nerves so intensely that the pain extends from the intestines to the bladder.
