What could be causing persistent headache and nausea?

Generally, persistent headache accompanied by nausea may be caused by excessive fatigue, acute upper respiratory tract infection, hypertension, or other conditions. It is recommended to improve symptoms through lifestyle adjustments, medication, and other treatments.

1. Excessive fatigue: Frequent熬夜 (staying up late) may lead to physical exhaustion, resulting in headaches and nausea. It is advised to improve lifestyle habits and maintain regular sleep patterns.

2. Acute upper respiratory tract infection: Viral or bacterial infections may cause acute upper respiratory tract infections, often accompanied by symptoms such as fever, headache, nausea, and vomiting. It is recommended to take medications such as amoxicillin capsules or cefixime dispersible tablets under medical guidance.

3. Hypertension: High blood pressure may also lead to persistent headache and nausea. Long-term lack of exercise or unhealthy lifestyle habits may contribute to hypertension. It is recommended to take medications such as amlodipine besylate tablets or nifedipine sustained-release tablets as prescribed by a doctor.
