Dizziness is a common functional disorder of the brain and one of the common clinical symptoms. It is a sensation of dizziness, head swelling, light-headedness, shaking in the brain, and blurred vision. Dizziness can be caused by a variety of reasons, most commonly febrile diseases, hypertension, cerebral arteriosclerosis, craniocerebral trauma syndrome, neurological disorders, etc. It is also seen in anemia, cardiac arrhythmia, heart failure, hypotension, drug intoxication, uremia, asthma, etc. Dizziness is also often present in the early stages of depression. Dizziness can occur alone, but is often complicated by headache. When dizziness is accompanied by balance disorder or spatial disorientation, the patient feels that the peripheral environment or himself is rotating, moving or swaying, which is called dizziness. Etiology and pathology: 1, internal injury of emotion and spirit, Yang Sheng, combined with excessive irritation and anger, liver Yang is hyperactive, Yang rises and wind moves, dizziness develops; or due to long-term depression and irritation, Qi depression turns into fire, so that liver yin is darkly depleted, liver Yang is hyperactive, Yang rises and wind moves, disturbing the clear air, dizziness develops. 2.Disorderly diet damages the spleen and stomach, and weakness of the spleen and stomach causes dizziness due to lack of source of Qi and blood biochemistry and loss of nourishment of the clear orifices; or alcoholism, fatty and sweet, hunger and fatigue hurt the spleen and stomach, resulting in failure to transform the essence of water and grain, gathering dampness and producing phlegm, which causes dizziness due to blockage of phlegm and dampness and failure to lower the cloudy yin. 3. Trauma, surgery, head trauma or post-surgery, stagnation of qi and blood stasis, paralysis and obstruction of the clear orifices, resulting in vertigo. 4. Physical deficiency, prolonged illness, blood loss, and excessive exertion. The kidney is the root of congenital origin, and it stores essence and generates marrow. If the congenital deficiency does not fill the kidney essence, or if the kidney is deficient in old age, or if the kidney is injured by prolonged illness, or if the room is overworked, the kidney essence is deficient and cannot generate marrow. Or kidney yin deficiency, liver loss of nourishment, resulting in liver yin deficiency, yin does not control yang, liver yang hyperactivity, dizziness. Vertigo can occur after a prolonged illness or blood loss, when the deficiency is not restored, or after excessive labor and fatigue, when the qi and blood are weak, when the qi is weak, the clear yang does not spread, and when the blood is weak, the brain loses its nourishment. It is caused by deficiency of qi and blood, deficiency of kidney essence, resulting in emptiness of the brain marrow and loss of nourishment of the clear orifices, or hyperactivity of liver and yang, phlegm and fire, or stasis of blood blocking the orifices, which disturb the clear orifices and cause vertigo. The pathology of vertigo is mostly deficiency, so Zhang Jinyue said “deficiency is the most common cause of vertigo”, such as deficiency of liver and kidney yin, internal movement of liver wind, deficiency of qi and blood, loss of nourishment of clear orifices, deficiency of kidney essence, and loss of brain marrow. The actual evidence of vertigo is mostly caused by phlegm and turbidity obstruction, abnormal lifting and lowering, phlegm and fire reversal, upward violation of the clear orifices, stasis of blood, and paralysis of the clear orifices. During the pathogenesis of vertigo, various etiological factors can interact with each other and transform each other to form a mixture of deficiency and reality; or yin damage and yang, and yin and yang deficiency. Liver wind and phlegm fire can disturb the clear orifices, and further development can cloud the clear orifices and block the meridians, resulting in stroke; or sudden reversal of qi, temporary closure of the clear orifices or loss of nourishment, resulting in fainting. Six causes of dizziness in the elderly 1, anemia elderly people such as dizziness, weakness, pale performance, should go to the hospital to check to see if anemia. In a healthy state, the amount of hematopoietic tissue present in the body of the elderly and the quality and quantity of hematopoiesis has declined, and the aging of the red blood cells themselves makes their utilization of iron much worse than before. Therefore, the elderly are prone to anemia if they do not pay attention to nutritional care. In addition, anemia can be secondary to indigestion, peptic ulcer, gastrointestinal bleeding and chronic inflammatory diseases in elderly patients. 2. High blood viscosity, hyperlipidemia and thrombocytosis can increase blood viscosity and slow blood flow, resulting in insufficient blood supply to the brain and symptoms such as fatigue, dizziness and weakness. There are many causes of hyperlipidemia, the most important one is the unreasonable structure of diet, patients eat a lot of high-fat and cholesterol food, and do not like to exercise. At present, the incidence of this type of disease has a rising trend. 3, cerebral arteriosclerosis patients feel dizzy, and often insomnia, tinnitus, emotional instability, forgetfulness, and numbness of the limbs. Cerebral arteriosclerosis makes the internal diameter of cerebral blood vessels smaller, and blood flow in the brain decreases, resulting in insufficient blood and oxygen supply to the brain, causing dizziness. 4, cervical spondylosis Often neck tightness, limited flexibility, occasional pain, numbness and coldness of the fingers, and a feeling of heaviness. Cervical spine hyperplasia squeezes the vertebral artery in the neck, causing insufficient blood supply to the brain, which is the main cause of dizziness in this disease. 5, hypertension hypertension patients in addition to dizziness, but also often accompanied by head swelling, panic, irritability, tinnitus, insomnia and other discomfort. 6, heart disease early coronary heart disease, the symptoms are still light, some people may not have chest tightness, palpitations, shortness of breath and other significant discomfort, only feel headache, dizziness, limb weakness, mental concentration, tinnitus or forgetfulness, etc.. The main reason for dizziness at this time is atherosclerosis of the coronary arteries of the heart, which makes the lumen thinner and narrower, causing ischemia and lack of oxygen to the heart. And insufficient blood supply to the heart can cause insufficient blood supply and cause dizziness. Treatment of dizziness: Chinese medicine health believes that the five internal organs of the human body have corresponding in the foot, often wash the feet can stimulate the foot acupuncture points, can enhance blood flow, dredge the meridians. Medical experts believe that if you can often massage the corresponding reflex zones of the foot, can play a role in promoting blood circulation, improve muscle resistance, the principle of foot reflex health care is to stimulate the skin of the foot with pressure, so much so that the internal organs and other parts of the body also play a role. The foot has many reflex zones corresponding to the organs or body parts, often massage the foot, but also exercise the foot muscles, promote blood circulation, strengthen the body, enhance immunity, prevention and treatment of headaches and insomnia a good method, the central depression of the heart of the foot is the kidney meridian Yongquan point, the palm of the hand depression is the pericardial meridian Laogong point, if often rub the heart of the foot, can effectively relieve headaches and insomnia. The specific method is: before going to bed using the stable Maishou massage wheel, sitting on a chair of moderate height, relaxed, the feet naturally droop, step on the sports massage wheel to move the feet back and forth, do not force too hard, to gradually increase the speed and strength, use to pay attention to alternate the choice of sports massage.
