F50-F59: Behavioural syndromes associated with physiological disturbances and physical factors
The group of conditions categorized as Behavioural syndromes associated with physiological disturbances and physical factors involves a broad range of psychiatric problems that are triggered or influenced by physical health disorders or physiological changes in the body. These conditions can arise from a variety of sources such as hormonal imbalances, nutritional deficits or excesses, physical illnesses, or external physical stressors. Common symptoms may include changes in eating behavior, disturbances in sleep, sexual dysfunction, or inexplicable physical symptoms. The diseases can manifest in different ways and progress based on the underlying physiological causes and the individual's psychological response to these changes. The conditions primarily affect the patient's mental health and behaviour due to their direct link to physical health and physiological conditions.
