Microscopic colitis: A common, yet often overlooked, cause of chronic diarrhea


 

Conclusion and future outlook

As a common cause of chronic watery diarrhea, MC will be commonly encountered in primary care and gastroenterology practices. The diagnosis should be suspected in patients presenting with chronic or recurrent watery diarrhea, especially with female gender, autoimmune disease, and increasing age. The management of MC requires an algorithmic approach directed by symptom severity, with a subgroup of patients requiring maintenance therapy for relapsing symptoms. The care of patients with MC will continue to evolve in the future. Further work is needed to explore long-term safety outcomes with budesonide and the role of immunomodulators and newer biologic agents for patients with complex, refractory disease.
