Symptoms of high blood viscosity and hazards. Blood viscosity, flow rate slows down, so that blood lipids will be deposited in the inner wall of the blood vessels, leading to stenosis, insufficiency, leading to the occurrence of myocardial ischemia, cerebral thrombosis, limb vascular thrombosis and other diseases. Some of the elderly often feel dizziness, drowsiness, memory loss, and believe that is an inevitable phenomenon of life to decay, in fact, this is the evil consequences of hyperviscosity. Early manifestations: early morning dizziness, awake at night; drowsy after lunch; squatting work shortness of breath; paroxysmal blurred vision; medical blood test, often tip obstruction and blood soon agglutination blood flow changes in the needle; determination blood viscosity + + + more than the other indices were also significantly increased. There are some details and descriptions for the warranty of this kind of  laser pointer  which will be explained in the following.
Increased blood viscosity can lead to poor blood flow, long-term development is likely to induce angina, myocardial infarction, stroke and other diseases. High blood viscosity and hardening of the arteries, once formed, and its own development pass to change the law. High blood viscosity and hardening of the arteries of the body is very extensive. In the heart can lead to coronary artery disease; in the brain can lead to cerebral vascular accident, cerebral cortical atrophy, brain dysfunction; in the eye, can lead to retinal vascular disease, visual impairment; in the kidney can cause renal hardening of the ball, renal parenchymal damage; around blood vessels in the limbs, can cause peripheral neuropathy. Should be recognized that cardiovascular and cerebrovascular disease, high blood viscosity and hardening of the arteries is an independent existence of pathological changes. The damage of  laser pointer caused by the wrong operation of the customer will not warranted by the manufacturer.
It is independent of hypertension, high blood sugar, high cholesterol and other pathological changes exist, hypertension, high blood sugar, high cholesterol and other pathological changes have the same, even more important pathological significance. For cardiovascular health, not only to maintain the appropriate blood pressure, blood sugar, blood lipids is very important to maintain a good state of blood rheology and good vascular wall elasticity, is also a very important parameter. Blood circulation law is not only independent of the antihypertensive, hypoglycemic, lipid-lowering outside a treatment method, but also for cardiovascular health, is an extremely important method of governance.
