If the patient is dizzy from hunger, first, whether it is hypoglycemia should be considered and blood sugar should be monitored promptly. If the patient is caused by hypoglycemia, oral sugar cubes, desserts or oral high sugar should be given promptly to correct hypoglycemia quickly and prevent hypoglycemic encephalopathy due to prolonged hypoglycemia. Dizziness caused by hypoglycemia, patients can also experience palpitations, sweating and other discomforts. In addition, low blood pressure can also cause dizziness in patients. If the patient is hungry, it can cause insufficient blood volume, which can cause the patient’s blood pressure to be too low, thus causing the patient’s blood supply to the brain to be impaired, thus causing posterior circulation ischemia, and the patient can show dizziness. At the same time, the patient may experience nausea, vomiting, and ataxia, and may also experience dysarthria. If hypotension is the cause, the patient should be given oral saline or intravenous saline.
