· Causes of dizziness ·
01
Otolithiasis, also known as benign paroxysmal positional vertigo.The onset of otolithiasis is very characteristic. It occurs suddenly when the body position changes, and the duration does not exceed 1 minute, most of which are tens of seconds.Don't underestimate this short tens of seconds, it will cause various discomforts, such as vision rotation, nausea, vomiting, dizziness, top-heavy, unsteady balance, etc.At present, the etiology of otolithiasis has not been fully clarified. It may be related to fatigue, staying up late, poor rest, high blood pressure, diabetes, changes in hormone levels, etc. It can also be associated with other ear or systemic diseases, such as plum Nier's disease, vestibular neuritis, idiopathic sudden deafness, otitis media, head trauma, migraine, and taking ototoxic drugs.
02
Orthostatic hypotension is when people's systolic blood pressure keeps falling and diastolic blood pressure keeps rising when a patient's body position changes dramatically, such as from upright to supine, or from supine to upright.Sometimes systolic blood pressure drops by 20mmhg and diastolic blood pressure rises by 10mmhg.As a result, it is easy to cause ischemia to the head, resulting in a temporary lack of blood supply to the brain.The main features are black eyes, pale face, white lips, dizziness, palpitation, difficulty breathing, and even fainting.
03
Cerebral insufficiency refers to the insufficiency of blood supply to a certain part of the human brain and causes brain dysfunction. The cause of cerebral insufficiency is mostly related to cerebral arteriosclerosis.If the blood supply to the brain is insufficient, dizziness is the most common symptom. In addition to dizziness, it is often accompanied by diplopia, that is, double vision, unsteady walking, tinnitus, etc., and some acute memory loss. , inattention.Therefore, insufficiency of cerebral blood supply should be treated in time to avoid cerebral infarction.
04
With the development of society, the pace of people's life and work is accelerating, and cervical spondylosis is changing from a geriatric disease to a common occupational disease.But not all cervical spondylosis causes dizziness.The prevalence of cervical spondylosis is indeed very high, about 15% in the general population, and as high as 50% in people over 60 years old.
Sympathetic cervical spondylosis
Symptoms are more complex and may include dizziness, poor sleep, etc.Many patients also experience gastrointestinal discomfort such as hiccups, nausea, and vomiting.Others experience unpleasant symptoms such as changes in blood pressure, irregular heart rate, and tinnitus.
vertebral artery type cervical spondylosis
The main manifestations are cervical vertigo, headache, neck and shoulder pain, tinnitus, visual disturbance and history of cataplexy. Individual patients have autonomic symptoms; X-ray films can show segmental instability and uncinate joint hyperplasia.
Cervical radiculopathy
Pain and stiffness in the neck, and a tingling sensation on the inside of the shoulder blade, which is exacerbated by coughing.There will be radiation tingling and numbness in the upper body, and in severe cases, there will be a feeling of difficulty in holding things.
cervical spondylosis
Walking unsteadily, it feels like walking on cotton.The lower limbs are heavy and numb, and it is very difficult to climb stairs. Some patients even experience abnormal symptoms such as burning or cold.Numbness in the upper extremities, and in severe cases, it is even difficult to eat.
cervical spondylosis
Mainly manifested as pain in the occiput, neck and shoulder, and limited head and neck movement due to pain.The neck muscles are tense and have tender points.X-ray films show changes in cervical curvature, and dynamic X-ray films can show intervertebral joint instability.
In fact, cervical spondylosis is divided into cervical spondylosis, sympathetic cervical spondylosis, vertebral artery type, myelopathy and radiculopathy.Only sympathetic type and vertebral artery type cervical spondylosis often have symptoms of dizziness, while other types of cervical spondylosis rarely have dizziness.Therefore, if you have cervical spondylosis, you may not necessarily experience dizziness.
· Prevention of cervical spondylosis ·
Pay attention to the correct posture of the head and neck, and insist on leaning forward, backward, left and right 1-2 times every day for 10 minutes.
To maintain a good sleeping position, it is best to use a soft pillow to maintain the physiological curvature of the cervical spine.
When working, maintain a comfortable posture that neither looks up nor bows down.1 hour after long hours of work to move the head and neck, so that the cervical ligament muscles get a proper rest.
Do not strain your neck when looking up at TV, preferably at eye level.
These methods can not only prevent cervical spondylosis, but also prevent the recurrence and aggravation of cervical spondylosis.
Dizziness is a symptom that everyone is more likely to encounter in life.If you are often dizzy, you can record your dizziness symptoms and the duration of the attack, and go to the hospital in time.
