Improve quality of life. Directly applicable therapy concepts that have proven effective. The subjective suffering of individuals with functional disorders is very high, and conventional medicine often cannot provide sufficient help. The following indications are presented in a practice-oriented manner in this book: irritable bowel syndrome, functional dyspepsia, overactive bladder, functional (psychogenic) respiratory diseases, functional cardiovascular complaints, and burnout syndrome. Naturopathy offers promising approaches in this context. The author presents holistic therapy suggestions that have proven effective both as complementary to conventional medical treatment and often as a standalone form of therapy.
