Answer:
Hypoxia is a medical condition in which oxygen is no longer sufficiently reaching your cells. It can be caused in a number of ways:
- If your airway is closed, such as when you're choking on food or you're drowning, your lack of breathing will cause hypoxia
- Toxins in the blood, such as carbon monoxide, can prevent blood from absorbing oxygen
- Stagnant hypoxia can result from high G-forces, such as when a fighter pilot pulls a turn or you go through a spiral in a roller coaster. This type of hypoxia specifically affects the brain
- Severe bleeding can lead to hypoxia if there isn't enough blood to transport oxygen
- Other medical conditions can cause your cells to prevent oxygen transport across the cell membrane. Genetic conditions are rare but poisons and toxins can cause this
