When a death is officially designated as being due to “natural causes,” it is a formal determination made by medical and legal authorities. This classification signifies that the person’s passing resulted solely from internal factors, such as a disease process or the effects of aging known as senescence. A death ruled natural excludes any external intervention, trauma, or intentional action as the underlying reason for the body shutting down. This designation is recorded on the official death certificate and is used for public health and statistical purposes.
The Standard Classifications of Death
The process of officially classifying a death involves a distinction between the Cause of Death and the Manner of Death. The cause is the specific injury, disease, or condition that leads to death, such as a heart attack, lung cancer, or a stroke. The manner is a high-level categorization of the circumstances under which the death occurred, making it primarily a legal determination.
In most jurisdictions, there are five recognized manners of death: Natural, Accidental, Suicidal, Homicidal, and Undetermined. The Natural classification is the most common, accounting for approximately 85 to 92 percent of all deaths recorded each year. This reflects that the vast majority of people die from chronic or acute internal physical processes.
Understanding the difference between the two terms is important for public health data and legal proceedings. For instance, a person’s cause of death might be a cerebral hemorrhage, but the manner of death is classified as Natural because the hemorrhage was due to underlying hypertension. Conversely, a cerebral hemorrhage sustained during a fall would be classified as an Accidental manner of death.
Specific Criteria for a Natural Ruling
A death is classified as natural when it is attributed entirely to disease, old age, or a breakdown in the body’s internal functions. This includes the progression of chronic illnesses like advanced kidney failure, congestive heart failure, or various forms of cancer. It also encompasses acute, sudden medical events, such as a massive pulmonary embolism or a fatal cardiac arrhythmia.
The central principle guiding a natural ruling is the exclusion of any contributing external factors. If a person’s death is caused by an illness, that illness must not be the consequence of a preventable injury or environmental exposure. For example, pneumonia is natural if it follows general illness, but not if it develops as a complication following a severe burn injury or a fractured hip sustained in a fall.
Forensic specialists often employ the “but-for” principle to determine the manner of death. The question asked is whether the person would have died when they did, but for the external factor or injury. If the injury hastened or caused the death, the manner is classified as non-natural, even if the final medical event was a heart attack.
A person dying from a known terminal condition, such as a debilitating neurological disease, is a clear-cut example of a natural death. Even cases involving infectious diseases, like a fatal case of influenza or bacterial sepsis, are classified as natural because the microorganisms are considered internal pathological processes.
Certifying the Death
The process of formally certifying a death as natural depends largely on the circumstances surrounding the person’s passing. In the most straightforward cases, such as an anticipated death in a hospital or hospice, the attending physician typically completes the death certificate. This occurs when the person has been under continuous medical care for a known, terminal condition, and the physician is confident in the underlying cause of death.
The physician must have seen the patient within a specific timeframe, often within the last few weeks, to sign the certificate without a full investigation. This certification requires the doctor to list the sequence of conditions that led to the death, culminating in the underlying natural cause.
However, if a person dies unexpectedly, is found alone, or has no recent medical history, the case must be reported to the medical examiner or coroner. These officials investigate sudden, suspicious, or unwitnessed deaths to ensure no foul play or public health risk is involved. Even if the death appears due to disease, the medical examiner must rule out non-natural manners before certifying it as natural.
The medical examiner may order a limited external examination or a full autopsy if the circumstances are unclear, such as a young person dying suddenly without any known illness. If the investigation confirms the death was caused by an internal, unpreventable medical condition, like an undiagnosed heart defect, the manner is ultimately ruled natural.
