Treatment options
The following list of medications are related to or used in the treatment of this condition.
How can I manage my symptoms?
- Eat a variety of healthy foods. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. You may need to eat several small meals throughout the day. Avoid spicy foods, caffeine, chocolate, and foods high in fat.
- Drink liquids as directed to help prevent dehydration. Good liquids to drink include water, juice, and broth. Ask how much liquid to drink each day. You may need to drink an oral rehydration solution (ORS). An ORS contains a balance of water, salt, and sugar to replace body fluids lost during diarrhea.
- Start to exercise when you feel better. Regular exercise helps your bowels work normally. Ask about the best exercise plan for you.
- Ask about probiotics. You may need supplements that help balance the bacteria in your colon. This may help decrease you symptoms.
How can I help prevent microscopic colitis?
- Wash your hands. Wash your hands in warm, soapy water for 20 seconds before and after you handle food. Wash your hands after you use the bathroom, change a diaper, or touch an animal.
- Clean food and areas that come in contact with food. Rinse fruits and vegetables in running water. Clean cutting boards, knives, countertops, and other areas where you prepare food before and after you cook. Wash sponges and dishtowels weekly in hot water.
- Cook food all the way through. Cook eggs until the yolks are firm. Use a meat thermometer to make sure meat is heated to a temperature that will kill bacteria. Do not eat raw or undercooked chicken, turkey, seafood, or meat.
- Store food properly. Refrigerate or freeze fruits and vegetables, cooked foods, and leftovers.
- Drink safe water. Drink only treated water. Do not drink water from ponds or lakes, or from swimming pools that do not contain chlorine. Drink bottled water when traveling.
