How is sudden dizziness, palpitation and vomiting?

Dizziness is a manifestation of brain dysfunction. Common in fever, hypertension, cerebral arteriosclerosis, craniocerebral trauma syndrome, neurosis, carsickness, seasickness, excessive alcohol and tobacco. Also seen in anemia, arrhythmia, heart failure, hypotension, drug poisoning, uremia, asthma and so on. Early depression often leads to dizziness. When dizziness is accompanied by balance perception disorder or spatial perception orientation disorder, patients feel that the surrounding environment or themselves are rotating, moving or shaking, which is called dizziness. The common types of dizziness are: ① cerebral dizziness. It can be seen in cerebral blood circulation disorder caused by cerebral arteriosclerosis (such as basilar arteriosclerosis) or cervical osteoarthrosis, or transient cerebral blood supply insufficiency caused by it. Symptoms include dizziness, sleep disorder, memory loss, occipital headache, paraplegia, speech disorder and irritability. Often appear or aggravate when the body position changes. The disease develops slowly. ② Cardiogenic dizziness. It can be seen in acute cardiogenic cerebral ischemia syndrome, which is an acute cerebral ischemia caused by cardiac arrest, paroxysmal tachycardia, paroxysmal atrial fibrillation and ventricular fibrillation, accompanied by dizziness, dizziness, stomach discomfort and syncope. ③ Vascular inhibitory vertigo. More common in frail young women. Emotional tension, pain, fear, bleeding, sultry weather, fatigue, fasting and insomnia can all be triggered. Symptoms include dizziness, dizziness, nausea, epigastric discomfort, pallor, cold sweat and so on. At this time, the blood pressure drops and the pulse is weak. ④ Drug-induced dizziness. Streptomycin, neomycin, kanamycin and gentamicin poisoning are common. Besides dizziness, there are also sensorineural deafness caused by vertigo and cochlear nerve injury. Besides dizziness, chronic lead poisoning also manifests as neurasthenia syndrome, hypothermia and anorexia. Functional hypoglycemia can cause dizziness, palpitation, fatigue and other manifestations, such as trembling on an empty stomach or when exerting force, and sometimes convulsions and loss of consciousness may occur. When nervous or hyperventilating, due to the increase of carbon dioxide output, respiratory alkalosis and hypoxia of brain cells may occur, causing dizziness, fatigue, numbness of face, hands and feet, etc. And you may have a sense of trance. Patients with dizziness should know their medical history in detail and have a comprehensive physical examination. Hearing examination, vestibular function examination and fundus examination should be done when necessary. According to the condition, they can also do cerebrospinal fluid examination, head or cervical X-ray photography, electrocardiogram, EEG and brain CT scanning. The treatment of dizziness is mainly etiological treatment.
