Anoxia is a condition brought about by hypoxia where the brain or body is deprived of oxygen. It is important to note that for every form of anoxia, it has a different external or internal cause.

When it comes to the internal causes, it generally includes insufficient oxygen to the blood vessels or heart. As for the external causes, it includes reduced oxygen or being exposed to environmental toxins.

Types of anoxia

Anemic

This type of anoxia occurs if the blood could not transport adequate oxygen throughout the body to allow optimal functioning of the organs.

Hemoglobin is utilized to deliver oxygen to the tissues and organs. If the blood does not have enough hemoglobin or it is ineffective, the oxygen supply drops. The lack of oxygen can lead to anemic anoxia.

Toxic

anoxia

Carbon monoxide poisoning is the usual cause of toxic anoxia.

The toxic form develops if the individuals takes in toxins or other chemicals. This prevents the blood from transporting oxygen effectively all over the body.

Carbon monoxide poisoning is the usual cause of toxic anoxia. It is important to note that carbon monoxide is generated if gas is utilized as fuel. Fireplaces, faulty gas stove or furnaces can fill the house with carbon monoxide. In addition, it is also present in vehicle fumes.

Stagnant

Stagnant anoxia occurs if blood does not reach the brain or other body parts that require it. This can arise if the blood is transporting abundant oxygen and hemoglobin.

Heart issues are the usual causes of this type of anoxia such as:

  • Stroke
  • Heart attack
  • Heart failure
  • Erratic heartbeat

Anoxic

This form of anoxia develops if there is not enough oxygen in the body. In case there is insufficient oxygen to breathe in, the individual could not acquire enough oxygen to the bloodstream.

The condition can occur if at high altitudes. Most of these symptoms are generally part of a condition known as altitude sickness. Physical exertion while at high altitudes can worsen the effects of anoxic anoxia. The reason for this is that the body necessitates more oxygen but could not get enough from the air.
