This theory, founded by Freud and later developed by other researchers, states that psychosomatic symptoms arise as a result of unconscious psychological conflicts, especially those related to the repression of emotions and the inability to express inner drives and desires. Repressed emotions such as anger, anxiety, or aggression are converted into compressed psychological energy, and without finding an emotional or behavioral outlet, they are transformed into physical symptoms. In this way, the body becomes an arena for the expression of internal conflicts that a person cannot face directly. This theory helped to draw attention to the crucial role of the unconscious psyche in the formation of physical diseases, although it was criticized for its interpretive nature and the difficulty of experimental verification.
