Dizziness, nausea and vomiting in the morning may have a lot to do with the change of posture. Pay attention slowly when changing posture, don't stand suddenly, and pay attention to the existence of high blood pressure and hyperlipidemia at ordinary times, which will lead to poor blood vessel elasticity and affect blood supply to the brain.

Another condition is hypertension, which is very high and uncontrolled, and can also cause dizziness, nausea and vomiting.

If this happens frequently, you'd better go to the hospital for examination.
