Unexplained physical troubles, which have no apparent organic cause, may be psychological in so-called "psychosomatic" diseases, said German psychotherapist Barbara Lübisch.

For example, constant stress causes high blood pressure, headaches, back and joint pain, or digestive problems such as abdominal pain, diarrhea, irritable bowel syndrome, tinnitus or skin itching, she said.

Feelings of anger, frustration and frustration also affect the autonomic nervous system, which is manifested by heart palpitations, severe sweating and high blood pressure.

Lopez said that the use of psychotherapy after the exclusion of the organic causes of these physical troubles through medical tests; as usually physical symptoms disappear on their own after treatment of the real psychological cause, which is behind them.

In addition to psychotherapy applications such as behavioral or analytical therapy, the treatment program may also include relaxation techniques such as yoga, meditation, progressive muscle relaxation and self-stimulation, as well as pharmacotherapy such as psychotropic medications and analgesics.

On the other hand, Lopez pointed out that physical illnesses can also cause mental illness; for example, patients with cancer or stroke often suffer from depression.
