Symptoms of dizziness after eating seafood may be related to an allergy to seafood. Patients usually have a rash, itching, nausea, vomiting, mental discomfort or stomach upset. You can take anti-allergy drugs such as loratadine, or you can take patchouli, drink more warm water, and eat as lightly as possible. Dizziness after eating seafood may also be related to elevated blood pressure. If blood pressure exceeds 150/100 mmHg, you can take antihypertensive drugs such as enalapril or nifedipine. If the dizziness is caused by cervical spine disease, you can do hot compresses on the neck and take cervical rejuvenation pellets. If the dizziness is caused by anemia after eating seafood, you can take oral blood supplements, and if your blood sugar is low, you should eat foods with high sugar content. If it is related to poor sleep, ensure sufficient sleep and eat calming food.
