One only sees what one looks for, one only looks for what one knows.
Modern medicine has divided us, human beings, into different systems and areas: cardio-vascular system, digestive syste, nervous system, etc. According to this division different medical specialties have been created, each concentrating on a particular bit of the human body: cardiology, gastro-enterology, gynaecology, neurology, psychiatry etc., etc. There is a reason for that. Medical science over the years has accumulated an enormous amount of knowledge. No doctor in the world can possibly know it all in detail, so specializing allows doctors to concentrate on a particular area of knowledge, to learn it thoroughly and to become an expert in that area.
However, from the early years of this specialization many doctors have recognized a problem developing. A specialist in a particular area tends to pay attention to the organs which he or she knows best, ignoring the rest of the body. The fact that every organ in the body exists and works in contact with the rest gets forgotten. The body lives and functions as a whole, where every system, organ, tissue and even cell depend on each other, affect each other and communicate with each other. One should not look at, let alone treat, any organ without taking the rest of the body into account.
One area of medicine is particularly prone to look at its organ separately from the rest of the body. That area is psychiatry. Mental problems are examined from all sorts of angles: genetics, childhood experiences, and psychological influences. The last thing that would be considered is looking at the patient’s digestive system. Modern psychiatry just does not do that. And yet medical history has plenty of examples where severe psychiatric conditions were cured by simply “cleaning out” the patient’s gut.
The vast majority of psychiatric patients suffer from digestive problems, which are largely ignored by their doctors. The gut-brain connection is something which, for some reason, many modern doctors do not understand. As they give out millions of prescriptions for antidepressants, sleeping pills and other drugs, which the patients have to place into their digestive systems in order to affect their brains, they still fail to see the connection between the digestive system and the brain.
