Prevention methods of increased blood flow resistance: 1. Rational use of medication. Patients suffering from high blood viscosity should be treated with effective symptomatic drugs under the guidance of a doctor, and should never take the initiative to buy drugs without permission. 2. Drink water frequently. The easiest way to prevent the increase of blood viscosity is to drink more water, water is very important to the human body, blood contains 80% of water. Water can play a role in the body’s chemical reactions, regulate the HP value of blood, reduce blood lipids, take away the role of sticky substances on the walls of blood vessels. Drinking water should pay attention to the timing, such as the morning before waking up, before each meal to drink water, the effect is particularly good. Once the body is well hydrated, the sticky blood can be diluted. 3, adjust the food structure, pay attention to a reasonable mix. Usually advocate low fat, low salt, low sugar, high protein diet, eat more vegetables, fruits, less animal offal, fried food. Dinner should not eat more meat and thick food, usually vegetarian-based, coarse and fine grains with. 4, focus on the use of food that can dilute the blood. Can inhibit platelet aggregation, prevent thrombosis of food such as black fungus, garlic, onions, mushrooms, strawberries, pineapples, etc., with aspirin medicinal anticoagulant food such as tomatoes, red grapes, oranges, etc., with lipid-regulating effect of spirulina, parsley, carrots, konjac, hawthorn, nori, kelp, walnuts, etc.. In addition, some foods rich in lecithin, such as soybeans and soy products, poultry eggs, fish, etc., can also make the formation of blood clots less likely. 5, to develop a good routine, maintain a happy state of mind, avoid excessive mental tension. Because emotional excitement easily causes vasoconstriction, which affects the flow rate of blood and increases the viscosity of blood plasma. At the same time, adhere to exercise, and participate in more non-intense group activities. Promote their own blood circulation, so as to improve the viscosity of blood. 6, quit smoking. Smoking can make the oxygen content of the blood is greatly reduced, the nicotine in the cigarette will also lead to vasoconstriction, causing adverse results. Smokers quit smoking as early as possible to help prevent the increase in blood viscosity.
