Tangible components are the material basis of blood viscosity. Visible components that can thicken blood include red blood cells and protein. The more red blood cells, the higher the blood viscosity; The more protein, fat and sugar in plasma, the thicker the blood; The influence of fibrinogen content in blood on blood viscosity can not be ignored. When fibrinogen increases, blood viscosity will increase obviously. Protein components in blood, such as globulin and fibrinogen, increase, and they combine with red blood cells to form a network, which increases the resistance of blood flow; The structure of red blood cells and platelets changes, congealing into blocks and blocking blood vessels; Cells in blood, such as red blood cells, have weakened deformability and cannot pass through small blood vessels smoothly, thus increasing the viscosity of blood.
There are also non-blood factors that thicken blood. Under the same conditions, some environmental factors also affect blood viscosity, such as high blood viscosity in summer and low blood viscosity in winter; High in the morning and morning, low in the evening and afternoon; Rainy, sultry, low pressure, sunny and low; High after a thick meal, low after a light meal; Have loose bowels, sweat more, and drink enough water. Some of the above factors are related to water balance, some are related to the increase of visible components in blood, and some are related to human biological clock. Understanding these laws is helpful to prevent blood thickening and related diseases.
How do you know your blood is getting thicker? Although blood thickening will not cause obvious symptoms such as anemia and blood loss, you can still feel some "clues", but be careful-
I feel dizzy, not awake and dull in the morning. Generally, you have to wait for breakfast before you gradually wake up. I feel sleepy after lunch and need to sleep for a while, otherwise I will be listless all afternoon. On the contrary, my mental state is particularly good after dinner.
Squatting down to work, panting. When squatting, the blood flowing back to the heart and brain is reduced, and the organs such as lungs and brains are ischemic, which leads to difficulty breathing, so there is asthma.
Paroxysmal blurred vision. The blood thickens, the flow rate slows down, the blood can not fully nourish the optic nerve, or the optic nerve or retina is temporarily ischemic and hypoxic, and the vision is blurred.
If the middle-aged and elderly people have the above symptoms, it should be suspected that the blood is sticky. It is best to go to the hospital for hemorheology examination in order to make a clear diagnosis.
Does blood viscosity need treatment? According to pathologists' research on the formation and change of blood viscosity, it is found that blood viscosity is influenced by many factors, such as diet, exercise, metabolism and external environment, different seasons, time and climate. Therefore, a person's blood thickness is not static, but constantly changing. For healthy people, you can rest assured, because the human body has a strong regulatory ability to maintain the balance and relative stability of the blood environment, so that you have no pathological manifestations, so generally do not need special treatment.
However, it should be noted that middle-aged and elderly people have obvious symptoms of blood viscosity, especially those who already have hypertension, arteriosclerosis and diabetes. Drug intervention must be given in time, such as western medicine sodium alginate, enteric-coated aspirin, tea pigment, dipyridamole, traditional Chinese medicine salvia miltiorrhiza, Ligusticum chuanxiong, angelica sinensis, safflower and so on. Of course, these drugs must be used under the guidance of a specialist to avoid mistakes. An easier way to prevent or eliminate blood thickening is to adjust your lifestyle. Adjusting lifestyle can be summarized as: drinking more water is a quick-acting diluent. The water loss after a deep sleep and the water consumed when digesting food are both factors that thicken human blood. Drinking water can dilute blood immediately. But to drink water scientifically, we must first grasp the opportunity, such as getting up in the morning, drinking 200 ml of water 1 hour before three meals, and going to bed at night. Secondly, choose water with good dilution effect: salt water can promote cell dehydration, which is insufficient; Cold water stimulates the contraction of gastrointestinal blood vessels and hinders the absorption of water into the blood, so it is not suitable for drinking; Pure water is too pure, and its hypotonic state will make water quickly enter cells, and the effect of diluting blood is not ideal. The ideal dilution water is boiled water or light tea at 20℃ ~ 25℃, and its tension and density are close to blood and tissue cells, which is worth popularizing.
Eat more foods that can dilute blood, such as black fungus, onion, bell pepper, mushroom, strawberry, pineapple, lemon and other fruits that can inhibit platelet aggregation and prevent thrombosis; Foods that have anticoagulant effects similar to aspirin include tomatoes, red grapes, oranges, ginger and so on. There are celery, carrot, konjac, hawthorn, seaweed, kelp, corn, sesame and so on. Vegetables and melons and fruits are rich in vitamin C and crude fiber in addition to a lot of water. Vitamin C can reduce blood lipids, and crude fiber can prevent the absorption of cholesterol in the intestine, which is beneficial to reduce blood viscosity. Eating more soybeans is rich in lecithin, which is an emulsifier. It can make cholesterol particles in blood become smaller and remain suspended, which is beneficial to the utilization of lipids by tissues through blood vessel walls, and can reduce blood cholesterol and improve blood viscosity. Eat less animal offal, animal fat and sweets. Animal viscera such as brain flower, pork belly, fat intestine and animal fat contain a lot of cholesterol and saturated fat, which can aggravate the degree of blood thickening and promote arteriosclerosis. Sweets are rich in sugar, which can increase triglycerides in human blood and increase blood viscosity. Therefore, three meals should be light, mainly vegetarian, and coarse grains should be flour and rice.
What is thick blood?
Blood hyperviscosity is medically called hyperviscosity, which is easy for middle-aged and elderly people and can be diagnosed by hemorheology examination. The main factors affecting blood viscosity are: blood cell factors, such as the number, size and shape of blood cells, erythrocyte deformability, platelet function and so on. Plasma factors, such as plasma protein (especially fibrinogen, immunoglobulin), blood sugar, blood lipid, fibrinolytic activity, etc. Vascular factors, such as vascular length, diameter and intimal smoothness. Other factors, such as mood, lifestyle, smoking and drinking. If the above factors are abnormal or abnormal, blood viscosity can occur.
□ Consequences of blood viscosity
1. Blood flow is slow, such as rough intima (atherosclerosis). At the same time, platelets are easy to aggregate and rupture to form thrombus, leading to cardiovascular and cerebrovascular diseases.
2. Blood stasis, poor circulation and insufficient blood and oxygen supply can cause dizziness, chest tightness, shortness of breath, fatigue and other symptoms.
3. Damage the great blood vessels and microcirculation, and accelerate the occurrence and development of complications in diabetic patients.
4. It is easy to make cancer cells of cancer patients grow, spread and transfer in the body, which affects the therapeutic effect of anticancer drugs.
□ Prevention and treatment measures for blood viscosity
Dietotherapy should be light and eat more coarse grains, green leafy vegetables and fruits, such as soybeans, corn, oats, buckwheat, onions, auricularia auricula, tomatoes, oranges, carrots, apples, kiwis and so on. These foods have the functions of lowering blood lipid, inhibiting platelet aggregation and preventing thrombosis. Animal fats (especially animal viscera) and sweets will increase blood lipids and increase blood viscosity, so you should eat less.
Quitting smoking, limiting alcohol, drinking more water, smoking a lot and drinking a lot can increase blood viscosity. Drinking a large glass of boiled water after getting up in the morning and before going to bed at night can reduce the blood viscosity. You can drink more tea at ordinary times. Drinking tea can not only replenish water and dilute blood, but also reduce blood fat and fight cancer.
Drug therapy can be administered under the guidance of a doctor, such as lipid-lowering drugs for those with high blood lipids, hypoglycemic drugs for those with high blood sugar, dipyridamole for those with strong erythrocyte aggregation, adenosine triphosphate for those with poor erythrocyte deformability, Agkistrodon halys antithrombotic enzyme for those with high fibrinogen, aspirin for those with strong platelet aggregation, blood dilution for those with high erythrocytosis, and traditional Chinese medicines for promoting blood circulation and removing blood stasis, such as Salvia Miltiorrhiza, Chuanxiong, Carthamus tinctorius, Persimmon and Angelica.
Insisting on physical exercise, such as walking, jogging, playing Tai Ji Chuan and doing aerobics, can accelerate body fat metabolism and reduce blood lipid and blood viscosity.
The life practice of reducing or eliminating mental stress proves that long-term mental stress or excessive psychological stress can easily lead to an increase in blood viscosity. Therefore, we should keep a cheerful mood and free ourselves from the stressful situation.
