Lack of oxygen to the brain is a dangerous disease, with the risk of causing brain cells to be destroyed and permanently damaged. Recognizing the body's response to cerebral ischemia helps us to detect the disease early and take timely measures.1. What is lack of oxygen to the brain?
A complex network of blood vessels is responsible for delivering oxygen and vital nutrients for the brain to function properly. Although it makes up only a small part of the total body weight, the brain requires a lot of energy. Specifically, the brain needs about 15% of the blood from the heart to get the oxygen and glucose it needs for daily activities.Therefore, if there is not enough blood flow to the brain to meet the metabolic needs, the brain will be deprived of oxygen.
Brain hypoxia is considered to be the third leading cause of death in the world after cancer and cardiovascular disease. Most notably, cerebral hypoxia accounts for 25% of all cerebrovascular accidents.
Brain oxygen deficiency in mild form, the patient will feel headache, fatigue, dizziness. Severe form can cause temporary loss of consciousness/memory, hemiplegia, dizziness, blue skin, fear of cold,... making life and work difficult.
Prolonged lack of oxygen in the brain will lead to a cerebrovascular accident with many serious sequels such as brain tissue death, cerebral infarction, also known as stroke, sudden death, hemiplegia,...
There are many Risk factors for hypoxia to the brain, but mainly due to:
Exogenous risk: Includes smoking or inhaling secondhand smoke, air pollution, chemicals, airborne dust or the effects of height. Endogenous risk: It is possible that the lungs and cardiovascular organs are not in good condition. Atherosclerosis is also one of the causes.
