If you are experiencing dizziness and nausea, it is important to stay hydrated and eat easily digestible foods. Resting and avoiding extreme heat can also help. Over-the-counter medications may help with vomiting, but if your symptoms persist or worsen, it is advisable to see a doctor. Look out for other symptoms such as dizziness when standing up, worsened dizziness with sudden head movements or changes in position, weakness, fever, severe vomiting, inability to eat, abdominal pain, confusion, or severe headaches. If any of these symptoms occur, seeking medical attention is recommended.
