Dizziness, sweating, and desire to vomit have the following four etiologies and require different dispositions and different treatments: a. In summer, such as dizziness, sweating, and desire to vomit, the most common are the precursors of heat stroke. At this time, it is necessary to immediately get rid of the hot and humid environment, to a cool, ventilated and dry room, to avoid vertical exposure to the sun, and to fully replenish body fluids to relieve the pre-stroke symptoms of dizziness, vomiting and sweating. Second, if dizziness, sweating and vomiting occur at room temperature, the most common cause is the premonitory symptoms of hypoglycemia. This is also accompanied by transient black haze, headache, nausea, and profuse sweating. At this time, sufficient glucose powder must be given, such as eating fructose or drinking drinks with more sugar, which can relieve the pre-hypoglycemic symptoms of dizziness, sweating and vomiting. Third, acute cerebrovascular accidents, such as acute cerebral hemorrhage or acute pre-infarction, will have symptoms of transient spasm of cerebral arteries, which will cause dizziness and reflex vomiting, accompanied by sweating. Fourth, transient hypotension can also cause nausea, vomiting and dizziness. However, dizziness is dominated by vertigo, accompanied by profuse sweating. In this case, the patient needs to be laid flat, and drugs that raise blood pressure, such as raw pulse drink, can be applied, and the patient’s condition can be observed symptomatically.
