Inflammatory bowel diseases are chronic and progressive inflammatory diseases of the gastrointestinal tract. Patients suffering from these diseases, especially if the standard treatment does not bring satisfactory results, more and more often turn to unconventional methods (complementary and alternative medicine). These methods are not only ineffective but also unsafe for the patient. For many of them, there is not enough scientific research. For this reason, the planning of such a method of therapy by the patient should be consulted with his or her doctor. The physician should discuss the potential benefits and risks of non-standard treatment with the patient and advise the patient not to stop conventional therapy.
