What Not To Eat When You Have Microscopic Colitis?

Colitis is an inflammation of the colon or large intestine. Microscopic colitis gets its name because the inflammation is so small that it cannot be seen with naked eyes. To diagnose it, a pathologist has to take a sample of tissue and run it under a microscope.

  • If having fruit juice, it should be diluted or watered-down, so that it is not strong on sugars.

  • Foods that are irritating for the digestive system should be avoided. These include any kind of fatty, spicy and oily foods.

Causes of Microscopic Colitis

There is no known cause of microscopic colitis as of now. Some researchers believe it to be a kind of auto immune disease. Some relate it to a long-term use of NSAIDs (non-steroidal anti-inflammatory drugs). Some other medicines are also linked with this condition.

Treatment For Microscopic Colitis

Microscopic colitis may improve on its own. However, if the microscopic colitis symptoms worsen or persist, there may be a need to start some treatment to relieve the symptoms. Microscopic colitis does not have a specific treatment as of yet. The treatment mostly aims at relieving the symptoms.

Along with changes in diet, some medicines can be prescribed by the physician. These medicines primarily include the ones that will reduce the diarrhea considerably. These are medicines like-

  • Loperamide, which is an anti-diarrheal drug.
  • Cholestyramine, which blocks the bile acids, as bile acids can also increase the diarrhea
  • Budesonide, which is a steroid
  • Mesalamine, which is an anti-inflammatory
  • Azathioprine, which is an immune-suppressant, as these may help to reduce the inflammation in severe cases.

Surgery may be advised, if the above-mentioned treatment and dietary changes are not effective in treating the symptoms of microscopic colitis. However, this is a very rare occurrence.

Prevention of Microscopic Colitis

As the definite cause of microscopic colitis is not yet known, it is difficult to prevent it. However, correct and prompt treatment may help in preventing the recurrence of the disease.

Microscopic colitis has no specific treatment. Symptomatic treatment is carried out to help relieve the diarrhea and other symptoms. Long-term prognosis of microscopic colitis is also not specific.
