Dizziness, nausea and urge to vomit after getting up from lunch break are recommended for observation if the discomfort is transient. If it persists, it is important to rule out that it is a cerebrovascular accident, including cerebral infarction, cerebral hemorrhage, subarachnoid hemorrhage, etc. It is recommended to go to the hospital immediately for a cranial CT or cranial MRI to rule out cranial vascular nerve problems and to identify the cause for symptomatic treatment. If this happens for a long time, it should be considered to be related to anemia or insufficient blood supply to the brain. It is recommended to draw blood for routine blood tests and liver and kidney functions, and if combined with severe anemia, to look for the cause of the anemia and see if there are chronic blood loss diseases.
