Are there purely psychosomatic diseases?
In the past, one separated diseases in which psychic triggers were suspected and where, for example under the microscope, a physical change could be detected, of diseases in which no physical damage could be diagnosed, despite all examination methods. Today one has strayed from this classification, so that the field of psychosomatic diseases has widened greatly.
Classical 7 of Pychosomatic
The psychoanalyst Franz Alexander was already in the middle of the last century of the opinion that certain diseases have mental causes and are based in the basic psychic structure of the individual: The classic sevens of psychosomatics included bronchial asthma, gastric and duodenal ulcers, chronic colitis colitis, atopic dermatitis, hypertension, chronic polyarthritis and hyperthyroidism. Later, diseases such as the intestinal disease Crohn's disease, coronary heart disease, allergies and some autoimmune diseases were added.
Today, however, we know that this theory is not true: For example, the discovery of the bacterium Helicobacter pylori on the one hand showed that quite a pathogen is responsible for the majority of gastric ulcers. In addition, many researches found no specific personality traits or conflicts that suggested a specific psychosomatic illness.
On the other hand, today we know very well that many diseases - not only those mentioned above, but also eating disorders such as bulimia or anorexia, sleep problems, many gynecological or urological problems, anxiety, addiction and even cancer - the mental state of the individual significantly influences the course of the disease and its manifestation. Why this is so, one does not know exactly - however, in the last 100 years famous psychoanalysts have developed different theories.
