What is the damage of insufficient oxygen to the human body

  As we all know, hypoxia can cause a series of physical problems, then what specific problems will cause, this article gives you a popularization:

1. Respiratory problems: Lack of oxygen can lead to dyspnea, shortness of breath, asthma and other symptoms, which may lead to hypoxic brain injury in severe cases.
2. Cardiovascular problems: Lack of oxygen can lead to an increased burden on the heart, a faster heartbeat, and increased blood pressure, increasing the risk of cardiovascular diseases such as heart disease, angina and myocardial infarction.
3. Brain problems: hypoxia can lead to insufficient oxygen supply to the brain, affecting the function of the nervous system, causing dizziness, headache, inattention, memory loss and other problems.
4. Immune system problems: Lack of oxygen can lead to decreased immunity, easy to contract diseases, and delay wound healing.
5. Energy metabolism problems: Lack of oxygen can reduce the energy metabolism of cells, leading to fatigue, muscle weakness, and weakness.
6. Digestive problems: Lack of oxygen can affect the normal function of the digestive system, leading to symptoms such as loss of appetite, indigestion and abdominal pain.
7. Other organ problems: Lack of oxygen can also cause damage to organs such as the liver, kidneys and visual system.
