Z56.3: Stressful work schedule

Stressful work schedule (ICD-10 code Z56.3) is a condition that describes a situation in which an individual's work hours, shift patterns, or workload cause significant stress. This is not a physical ailment in itself, but it can lead to physical and mental health problems over time. Stress induced by a demanding work schedule often presents itself in various ways, such as difficulty in concentrating, headaches, fatigue, or even in more severe forms like anxiety and depression. A person may also experience sleep disorders and changes in appetite or weight. The issue often progresses gradually, beginning with minor symptoms that potentially intensify if the stressful circumstances persist without any form of intervention or lifestyle modification. Both the nervous and endocrine systems can be affected due to the release of stress hormones like cortisol and adrenaline.
