Soft foods that are easy to digest, such as bananas, rice and applesauce, are good choices on a microscopic colitis diet, according to Mayo Clinic. Patients should drink plenty of water and fluids that contain electrolytes, potassium and sodium, such as broth or watered-down fruit juice.
Individuals suffering from microscopic colitis should avoid foods that are high in fiber, such as beans, vegetables and nuts, states Mayo Clinic. Other foods that may aggravate the condition include spicy, fried or fatty foods. Additionally, sugary sodas, alcohol and caffeinated beverages, such as coffee and tea, may make symptoms worse.
Microscopic colitis is an inflammation of the colon that causes cramping, diarrhea, dehydration and bloating, reports WebMD. As of 2015, doctors do not know what causes the condition; potential causes include toxins, bacteria or viruses. Aspirin, certain antidepressants and heartburn drugs increase a person's risk for microscopic colitis. The condition often goes away on its own, but patients should avoid foods and beverages that make symptoms worse.
To treat microscopic colitis, doctors sometimes prescribe a fiber supplement or over-the-counter medications, such as Imodium or Pepto-Bismol, according to WebMD. In the case of swelling, steroids, mesalamine and sulfasalazine may help. In rare instances, microscopic colitis sufferers may require surgery.
