During the new corona epidemic, some people useoxygen in the bloodWhen the machine tested itself, the oxygen concentration in the blood was always above 99%; but when I went for a health check, I found that “hearthypoxia“. Why?heartWhat are the warning signs of hypoxia?
3 typeshypoxiaConditions Vascular problems are common
People breathe 24 hours a day, so why lack oxygen?
Liu Zhongping, a cardiologist and director of the Yuping Clinic, said there are three situations that cause hypoxia:
The first is that there is not enough oxygen inhaled into the body.
Like drowning, choking on food, or getting COVID-19 or other lung diseasesoxygen in the blood。
Liu Zhongping pointed out that this situation belongs to the hypoxia of the whole body: when these patients use the blood oxygen machine to detect fingers, it is possible to measure the oxygen concentration in the blood.
The second is a poor blood supply.
The reason could be that blood vessels are naturally prone to spasms, resulting in poor blood flow, or acquired due to bad lifestyle habits, fat and bad cholesterol build up on the blood vessel wall and become thicker and thicker and blood vessels become increasingly tight and hardened, causingatherosclerosisso that the blood cannot flow smoothly into the tissue.
If the blood supply to tissues and organs is poor, local hypoxia will occur. For example, when the heart receives less oxygen, it can cause hypoxia.
Liu Zhongping pointed out that most hypoxia, including cardiac hypoxia, belongs to local hypoxia, which cannot be measured by a blood oxygen machine.
Other cases of local hypoxia due to poor blood supply include necrosis due to an accident that caused a limb to be squeezed by a heavy object, or people tying rubber bands to fingers and fingers that turn black due to flow altered blood, etc.
The third is the insufficient ability of red blood cells to carry oxygen.
The heme in red blood cells is responsible for transporting oxygen, and red blood cells are responsible for transporting oxygen throughout the body. If hemoglobin is insufficient, the ability of red blood cells to carry oxygen decreases. Likewise, without enough red blood cells, it cannot carry enough oxygen. Therefore, patients with poor blood cell function and severe anemia are prone to local hypoxia.
Ignoring 3 symptoms of hypoxia can lead to heart failure, myocardial infarction
Cardiac hypoxia can be called hypoxic lesions, ischemic heart disease, and the most important factor is the blockage of the coronary arteries of the heart. The onset of hypoxia can be divided into chronic and acute:
1. Acute cardiac hypoxia
When acute platelet aggregation occurs in the blood vessels, resulting inthrombusObstruction can cause acute hypoxia. Myocardial infarction belongs to this category: the attack comes quickly and violently, and people often fall quickly. Myocardial infarction can occur because blood vessel walls are weak or when a blood clot suddenly grows after being tired and not drinking enough water for the day.
2. Chronic cardiac hypoxia
Chronic cardiac hypoxia is more common than acute cardiac hypoxia.
The main reason is a poor blood supply, another reason is related to anemia. Liu Zhongping said that in the clinical diagnosis, the patient’s hemoglobin will be checked at the same time.
Symptoms of chronic cardiac hypoxia:Sense of chest tightness, chest pain, shortness of breath. If they are likely to occur while walking or exercising, be very careful.
Due to high cholesterol and smoking, many people’s blood vessels become increasingly narrow and they are prone to wheezing and chest pain when walking. But people tend to think it’s a trivial matter and ignore it when symptoms go away. Liu Zhongping stressed that if there is no timely treatment, the heart will be hypoxic for a long time, and the following conditions may occur: increasingly weak movement, severe arrhythmia, heart failure, myocardial infarction.
Chronic hypoxia can also become acute, causing a myocardial infarction. Therefore, if you have symptoms such as wheezing and chest tightness, it is recommended that you go to the hospital to check your heart, rather than relying on the blood oxygen machine to judge, let alone let it go.
The 5 most dangerous foods in this age group prevent cardiac hypoxia
Before menopause, most patients with cardiac hypoxia were men. The reason is that pre-menopausal women have female hormones to provide protection and their cardiovascular health is relatively healthy. Most female patients start having cardiovascular disease after menopause, so after menopause, the proportion of male and female patients will be close.
Cardiac hypoxia is more common in patients between the ages of 45 and 65, and regardless of whether it is men or women, the reasons are mainly caused by vascular stenosis and sclerosis and are linked to aging, cholesterol and to smoke. “If a person starts smoking and eating foods rich in fat and sugar from a young age, it has accumulated for more than 20 years. Once they are over 40, they are prone to seizures and reach their peak period at all. ‘age of 45, “Liu Zhongping said.
To prevent cardiac hypoxia, avoid smoking, reduce the consumption of foods high in fat and sugar, exercise more and avoid overwork.
At the same time, you can eat some foods that are good for blood vessels and blood cells:
1. Foods containing water-soluble dietary fiber
Water-soluble dietary fiber can reduce cholesterol absorption in the intestinal tract, expel bad cholesterol, help blood vessels flow smoothly, allow blood to flow smoothly into tissues, and avoid local hypoxia.
Foods rich in soluble dietary fiber: oats, potatoes (potatoes), squash, sweet potatoes, okra, mushrooms, seaweed, cauliflower, carrots, melons, apples, pears, bananas, kiwis, citrus fruits.
2. Fish
Fish is a good source of high quality protein and Omega-3 polyunsaturated fatty acids, which are good for blood vessels and red blood cells。
Protein helps in the production of red blood cells, Omega-3s preventatherosclerosisThe reason is that Omega-3s can help remove fat from blood vessels and stabilize atherosclerotic plaque.
An epidemiological survey in Greenland reported that the incidence of ischemic heart disease in Greenlanders is very low and is related to a diet rich in omega-3s.[1]
Fish rich in omega-3s include salmon, tuna, mackerel, herring, trout and sardines.
3. Allium and cruciferous vegetables
These two types of vegetables contain organosulfurized compounds that allow for regular blood flow in the arteries and prevent chronic hypoxia.
Studies have found that organosulfurized compounds can reduce cholesterol synthesis in liver cells and inhibit platelet aggregation. If the ability of platelets to clump together increases, it is easy to cause blood vessels to narrow.[2]
Organosulfurized compounds can also prevent atherosclerosis and re-occlusion of treated coronary arteries.
Common allium vegetables: Garlic, onions, leeks, scallions, and chives.
Cruciferous vegetables: cabbage (cabbage), cauliflower, broccoli (broccoli), cabbage, rocket, Chinese cabbage, radishes, Brussels sprouts.
4. Meat, fish and shellfish
Iron is a mineral necessary for heme synthesis. Without enough iron, heme synthesis is insufficient and the oxygen carrying capacity of the red blood cells will be relatively small. Liu Zhongping added that if the hemoglobin is insufficient, there will not be many red blood cells.
Meat, fish and shellfish are ideal iron complementary foods with a high iron content, because the human body’s absorption rate and animal iron utilization rate are better than those of vegetable iron.
Also, when eating iron-containing foods, supplement with fruits and vegetables containing vitamin C, which can promote iron absorption.
Fruits and vegetables rich in vitamin C are: guava, papaya, grapefruit, strawberries, kiwis, oranges, tomatoes and so on.
5. Eggs
Eggs are a fairly nutritious food, containing the nutrients needed to prevent anemia and produce heme and red blood cells: protein, vitamin B6, vitamin B12, folic acid, copper, iron, vitamin D, and more.
Some people worry that eating too many eggs can raise their cholesterol. But a 2018 review pointed out that cholesterol in food has little effect on the body, but saturated fatty acids can increase the risk of cardiovascular disease. The study states that eggs contain high-quality protein and minimal saturated fatty acids, and one large egg (50 grams), with only 1.56 grams of saturated fat, is a healthy and affordable food.[3]
By developing the habit of eating a balanced diet, you can naturally absorb these nutrients. Liu Zhongping shared that after taking drugs, developing good eating habits and exercising correctly, his patients’ cardiac hypoxia improved.
