Dizziness is a discomfort that many are more likely to experience. Many middle-aged and elderly people know that dizziness and headache are typical symptoms of high blood pressure and will take antihypertensive drugs as soon as they appear. There are many causes of dizziness in the elderly, and it is important to seek medical attention in a timely manner to find the “root cause” of the problem, rather than blindly using antihypertensive drugs. 1, poor sleep Many people once they get older, they will feel that the quality of sleep is not as good as before, not only difficult to fall asleep, but also easy to wake up early, drowsy during the day. Statistics show that the prevalence of insomnia in China over the age of 60 is 57%, of which 73% of insomnia patients have not taken any measures to listen to the torment of insomnia. Long-term poor sleep will certainly cause damage to health. A number of middle-aged and elderly people suffer from dizziness due to poor sleep, which is the most common cause of dizziness in middle-aged and elderly people. Some middle-aged and elderly people can be well improved by lifestyle interventions, while others need to resort to sleeping pills. When sleep improves, dizziness is naturally relieved. We remind that taking sleeping pills must be done under the guidance of a doctor, and that not taking the pills in a standard way may aggravate dizziness. 2, cerebral vascular sclerosis cerebral vascular sclerosis is a kind of arteriosclerosis, because it is easy to cause stroke and has a great danger, dizziness, headache is the early symptoms of cerebral vascular sclerosis, cerebral vascular sclerosis will cause dizziness because the oxygen and nutrients carried in the arterial blood can not “through” the exchange of hardened blood vessels to the brain cells The reason why cerebral vascular sclerosis causes dizziness is that the oxygen and nutrients carried in the arterial blood cannot be exchanged to the brain cells through the hardened blood vessels, resulting in long-term chronic lack of oxygen to the brain and dizziness. The headache caused by cerebral vascular sclerosis is mostly in the forehead and the back of the head, and the nature of the headache is mostly dull, and it is most likely to appear or worsen when the position changes. Cerebrovascular ultrasound, TCD transcranial Doppler and carotid ultrasound can be used to diagnose cerebrovascular sclerosis. By taking drugs to improve circulation and stabilize arterial plaque as well as hyperbaric oxygen therapy, dizziness can be significantly improved. 3, cervical spondylosis In middle-aged and elderly people, cervical spondylosis is also a common disease. Cervical spondylosis can also cause dizziness, called “cervical vertigo”. Cervical vertigo accounts for 50% of dizziness in people over 50 years old. There are two mechanisms by which cervical spondylosis causes dizziness. The vertebral artery in the neck is the “lifeline” of blood supply to the brain, and cervical spondylosis may lead to compression and narrowing of the vertebral artery in the neck, resulting in insufficient blood supply to the brain and lack of oxygen. In addition, cervical spondylosis may also lead to spasm of the arterial wall due to stimulation of the vertebral artery plexus, resulting in a series of symptoms of insufficient blood supply. In addition to cervical spondylosis, cervical trauma, degenerative changes in the cervical spine, osteophytes, inflammation, and soft tissue lesions in the neck, such as cervical muscle injury, rheumatic cervical myelitis, swelling of the cervical joint capsule, cervical disc herniation, ligament damage, and radiculitis, can also cause cervical vertigo. Cervical vertigo will be improved after effective treatment of cervical spine problems, which can be diagnosed by CT of the neck. 4. Heart problems In general, the typical symptoms of coronary heart disease are chest tightness, breathlessness and angina pectoris, but some people get dizzy mainly because coronary heart disease is caused by atherosclerosis and narrowing of the coronary arteries that supply blood to the heart, resulting in reduced blood supply to the heart. When the heart is chronically undersupplied with blood, its function decreases and its power to deliver blood to the whole body is insufficient. The brain is the highest part of our body, and the brain needs a lot of fresh blood at all times, so it is the most sensitive to the reaction of ischemia and hypoxia. When the heart is ischemic, it causes dizziness when the blood supply to the brain is reduced. Experts, through the heart specialist examination can find the relevant problems, and symptomatic treatment. 5, hypertension & hypotension Both hypertension and hypotension may cause dizziness. Dizziness is the most common symptom of hypertension. There are various reasons for dizziness in patients with hypertension: for example, high blood pressure enhances the pulsating sensation of the cerebral arteries, which in turn creates shocks and oscillations in the brain tissue, causing dizziness; some patients with chronically high blood pressure have adapted to higher blood pressure, and when blood pressure is lowered to normal by taking antihypertensive medication, dizziness may also occur due to maladjustment in cerebrovascular regulation. Patients with low blood pressure may also experience dizziness due to low blood pressure and insufficient power to transport blood throughout the body, resulting in cerebral ischemia and hypoxia. For patients with hypertension, in addition to medication, regular consumption of light salt water, especially in the morning, is also helpful in improving hypotension. In addition, taking some Chinese herbal medicines that have the effect of replenishing qi, such as red ginseng and astragalus, also have the effect of improving hypotension. Special reminder: morning exercise dizziness to stop After winter, the number of middle-aged and elderly people with dizziness symptoms will increase, mainly because the cold weather, blood vessels will contract, resulting in insufficient blood supply to the brain, causing dizziness. In particular, many middle-aged and elderly people like to practice in the morning, and a large part of the blood supplied by the heart has to be distributed to the limbs during the morning practice, and at the same time, the morning practice is generally upright, which is more likely to cause insufficient blood supply to the brain. Therefore, the elderly in this season must pay attention to keep warm, morning exercise to moderate, once the dizziness and other discomfort, must stop in time. In addition, many friends do not like to drink water at night, worried about frequent “night”. Winter weather is dry, home heating or sleep like open mouth breathing middle-aged and elderly people, more likely to cause the loss of body water and lead to blood thickening. Drinking more water at night will help dilute the sticky blood and reduce the risk of cardiovascular and cerebrovascular accidents.
