Death by natural causes

A death by natural causes results from an illness and its complications or an internal malfunction of the body not directly caused by external forces, other than infectious disease. For example, a person dying from complications from pneumonia, diarrheal disease or HIV/AIDS (infections), cancer, stroke or heart disease (internal body malfunctions), or sudden organ failure would most likely be listed as having died from natural causes. "Death by natural causes" is sometimes used as a euphemism for "dying of old age", which is considered problematic as a cause of death (as opposed to a specific age-related disease); there are also many non-age-related causes of "natural" death, for legal manner-of-death purposes.
