Can Massive Blood Loss Cause Brain Damage?

Follow Us:

Humans can lose a considerable amount of blood without difficulties or adverse effects.

However, severe internal or external bleeding may result in organ failure, seizures, coma, or death(1).

For example, hemorrhage, or an acute blood loss resulting from a damaged blood vessel, can lead to oxygen deprivation in the brain and, ultimately, brain damage(2).

Radiographers today employ imaging methods such as computed tomography (CT) and magnetic resonance imaging (MRI) to monitor brain states. Practitioners can use these diagnostic tests above to evaluate a patient’s brain anatomy (CT or MRI) without needing to perform surgery. Visit this page to know more about this.

For instance, a computed tomography scan can reveal the occurrence of an aneurysm (a weak area in a blood vessel). If the aneurysm bursts, a CT scan can identify blood that has flowed into the brain(3).

Aneurysm in a blood vessel can produce back pain comparable to sciatica and benefit from similar provisions for sciatica relief. However, when an aneurysm ruptures on the brain’s surface, it can cause brain damage(4).

Healthy habits, medication, and even alternative treatments such as essential oils and CBD oils(5) can help maintain blood pressure and prevent aneurysms.

Brain Injury and Blood loss

Traumatic brain injury (TBI) is a significant public health issue, with an estimated annual global occurrence of 69 million cases and an increasing prevalence over the last 25 years(6).

A mild traumatic brain injury can cause short-term damage to your brain cells(7).

A forceful impact or blow to the head or body frequently causes TBI. Bruising, damaged tissues and other physical injuries to the brain can occur with more acute traumatic brain injury. 

A traumatic brain injury can also damage several blood vessels in the brain. This event could develop into a stroke, blood clots, or other complications.

For example, sudden massive blood loss could result in severe oxygen deprivation of tissues (hypoxia) in the brain and increase the pressure inside the skull. This condition is known as increased intracranial pressure(8).

Multiple organ failures caused by abnormal pressure inside the brain can threaten the brain’s health.

Nearly all tissues enlarge when the body experiences trauma. Trauma can also cause brain tissues to require more oxygen for recovery.

The brain is unique because it lies inside a bone casing. This situation means that it is subjected to additional damage when it swells.

Due to blood vessel leakage, the brain swells in proportion to the amount of incurred damage.

Because the brain’s location is inside the skull, the brain swells even more because it has no area to expand.

As a result, there is a growth in internal pressure in the brain. This quick rise in pressure affects arterial pressure, altering and blocking blood flow to the brain(9).

As in the examples above, long-term brain damage can result from deficient oxygen supply in the brain.

Approximately 80% of TBI cases are mild traumatic brain injury (MTBI)10) and may only require minimum supervision.

However, individuals with a mild traumatic brain injury should constantly examine themselves for any chronic, aggravating, or new symptoms.

Patients should also set up regular appointments with their doctors to boost recovery.
