As I mentioned in previous articles, psychological problems can also be caused or exacerbated by vitamin and nutritional deficiencies (most notably vitamin D, vitamin B6 and B12 and iron). We know that no matter what kind of therapy it is, we can not look at body and mind separately. Those who choose to follow the path of psychotherapy to solve a psychological problem should first check possible vitamin- and nutrient deficiencies, hormonal imbalances and other diseases that could have a negative impact on the psychological problem. Psychotherapy is hard work. It’s like preparing for an exam when we have to study a lot, we need to eat well, sleep enough and do sport. The same applies to the “work” of psychotherapy. While psychotherapy we need to face our problems, our fears and traumas. More than overcome them we have to accept them as part of our life and learn to deal with them. This needs a lot of energy. But it is worth because psychotherapy can change your life positively. We need to prepare! Before beginning with the psychotherapy eventual deficiencies and diseases should be investigated and treated. This alone can already lead to a significant improvement in mental well-being of the patient, which in turn increases motivation and perseverance during the psychotherapy. Additional it may be possible to resign to pharmacotherapy. This has been found in particular for stress related disorders, like burn-out syndrome, depression, eating disorders, and certain sexual disorders, such as the psychogenic erectile dysfunction. And even during the psychotherapy the patient should pay attention to a healthy lifestyle. The collaboration between physician and psychotherapist is very important. The patient needs the support of both of them.
