Sweating and dizziness are mainly considered in the following 3 aspects: 1. transient ischemic attack, if the patient has risk factors for cerebrovascular disease, such as hypertension, hyperglycemia, hyperlipidemia, obesity, as well as alcohol consumption and smoking, the symptoms of sweating and dizziness should be considered as precursors of cerebral infarction and must be hospitalized. 2. hypoglycemic reaction, the patient may be caused by eating too little and 3, acute coronary syndrome, heart attack or patients with severe malignant arrhythmia, which causes a significant decrease in the ejection fraction of the heart within a short period of time, resulting in insufficient blood supply to the brain and causing sweating and dizziness. These are the main causes of drowsy sweating and dizziness.
