Burnout -- the type of extreme stress or fatigue that can lead to everything from respiratory problems to gastrointestinal issues -- is now officially a recognized mental health concern.
The World Health Organization (WHO) included burnout in its International Classification of Diseases, or ICD-11, a diagnostic tool for medical providers.
Burnout, called an "occupational phenomenon" by WHO, is described as "resulting from chronic workplace stress that has not been successfully managed." The guidelines note that burnout is only applicable related to work-induced stress.
