According to the Mayo Clinic, cystitis is an inflammation of the bladder. It may be caused by an infection, irritants, drugs or illness. Some cases of cystitis will become chronic, a condition known as interstitial cystitis. Frequently called IC, it is characterized by a feeling of pressure and pain in the bladder. While foods are not known to cause cystitis, certain things you eat can worsen the discomfort. The foods to avoid will vary for each person, but there are some commonly known "trigger" foods.

Eating to Manage Your Symptoms
You may need to avoid and reintroduce certain foods as you learn which foods trigger pain for you. Keeping a food diary may be beneficial. Avoid any foods to which you are allergic or intolerant. If you discover that a particular food worsens your symptoms, try a different brand, an organic version or a different cooking method. Do not restrict your diet to the point that you do not get all the daily nutrients you need. Drink adequate amounts of water with your meals.
