Psychosomatic gastrointestinal disturbances. A multifactor, interactional concept

Many common psychosomatic syndromes other than peptic ulcer and ulcerative colitis are referable to the gastrointestinal tract. Symptoms range from pain or polyphagia to teeth grinding or trench mouth. A multifactor concept of the influence of stress emphasizes the interactions of the behavioral and biologic states of the organism in producing physical symptoms and signs of illness.
