1, dizziness Dizziness is a very common symptom in daily life, most people will have more or less dizzy symptoms in their lives. But which dizziness is necessary to go to the hospital in time to seek medical attention, and which is simple to deal with yourself can be, the following I will briefly talk to you about their experience. 2, dizziness is usually divided into two main types, one for dizziness and one for vertigo. Dizziness: the head is stuffy and uncomfortable, the feeling of not being awake, heavy head and light feet, drunkenness-like feeling. Vertigo: a sudden feeling that the external environment is spinning, or its own rotation, its own shaking feeling, often accompanied by nausea and vomiting, panic, sweating and other symptoms, afraid to open their eyes, afraid to move. 3, the common causes of dizziness ① blood pressure is too high and too low will appear dizziness, normal blood pressure requirements in 60-90/90-140 (young women usually low blood pressure 90/60mmHg, more serious in the summer, overexertion, standing for too long, crowded air circulation occasions will show the symptoms of dizziness; another is too high blood pressure will also be dizzy, but sometimes patients are first dizzy after blood pressure increased) (We have to distinguish whether dizziness causes high blood pressure or dizziness occurs after high blood pressure). ② dizziness can occur when blood sugar is too high or too low (many people lose weight, eat very little or take diet pills, some people take hypoglycemic drugs indiscriminately can lead to hypoglycemia; diabetic patients do not carry out dietary control, like to eat whatever leads to high blood sugar, both cases will appear dizziness). ③Hematologic disorders: anemia due to various causes. ④Nervous dysfunction (menopause – menstrual disorders, episodes of excessive sweating, irritability, poor sleep; depressive states – poor sleep, fatigue, weight loss, decreased appetite, decreased interest). ⑤ Heart disease: coronary heart disease, arrhythmia, conduction block, etc. ⑥Ocular diseases: refractive error (myopia or hyperopia), eye muscle paralysis (strabismus, diplopia) (7) Sleep disorders (too little sleep or too much dream). ⑧Infection (fever). (⑨) Poisoning (CO poisoning, benzene poisoning-decorator). ⑩Head trauma syndrome, vertigo epilepsy, etc. 4, common causes of vertigo ① extracranial lesions (otogenic) – heavy symptoms, short duration, related to position change – otoliths; local inflammation of the ear, water in the vagus – Meniere’s disease, vaginitis) ② intracranial lesions: cerebellar and brainstem lesions, usually poor blood supply, in addition, it can also be infarction and hemorrhage in the cerebellum and brainstem, this (The situation is very dangerous, so the patient should be allowed to lie flat and sent to the hospital as soon as possible for cranial MRI to clarify the cause). Put the patient flat, do not move, call “120” as soon as possible, and carry the patient to the ambulance with a stretcher. If you do not have the condition to take the ambulance, you should let the patient move as little as possible or go to the hospital in a lying position. Activity will make the patient dizziness and vomiting aggravated. 6, auxiliary examination When encountering a case of dizziness, routine examinations include blood sugar, blood pressure, blood routine, electrocardiogram, and sometimes it is necessary to do cranial MRI, cervical spine film, cerebrovascular ultrasound, or head position evocation test, neuropsychological examination, etc. The examination items are selected according to the patient’s condition. 7, prevention Patients with low blood pressure, do not be too hot in the summer, appropriate to use some drugs that can raise blood pressure, like a raw pulse; hypertension patients must be serious about lowering blood pressure, reduce salt intake and fat intake, while increasing exercise; patients with diabetes often monitor blood sugar, do not randomly buy drugs to eat, the current market is a lot of health products to lower sugar, we should still try to use more regular drugs to lower sugar treatment. Patients with cervical spondylosis try to play less mahjong, less computer, head in a position for a little longer, appropriate activities cervical spine; in addition, do not sleep with a high pillow is also very important, because a lot of time in a day is in sleep, high pillow directly lead to cervical overflexion, very fatigue, easy to induce the occurrence of disease.
