Dizziness due to food poisoning is a common symptom and clinical manifestation. For patients with food poisoning, if vertigo occurs, they need to go to the emergency department of the hospital for treatment. At this time, symptomatic corresponding treatment measures should be given according to the severity of the situation, such as the severity of poisoning. Gastric lavage should be given regardless of the degree of poisoning, with 5000-8000 ml of saline to induce vomiting and throat picking for awake patients and intubation for unconscious patients. After gastric lavage, apply mannitol, magnesium sulfate or activated charcoal to induce diarrhea, and also give certain diuretics for diuretic treatment. In case of severe vertigo with loss of consciousness, symptomatic antidotes or blood purification must be administered.
