Somatic Symptom Disorder (SSD), Medically Unexplained Symptoms (MUS), and Functional Neurological Disorder (FND) remain some of the most challenging conditions in clinical practice. Their symptoms are often distressing, persistent, and frequently resistant to standard medical approaches. Growing evidence shows that clinical hypnosis, including symptom-focused suggestions, gut-directed hypnotherapy, and hypnotic techniques that support relearning in FND, can help reduce symptom intensity and improve overall functioning.
