Feeling nauseous and having a headache together can be caused by several common conditions. The most frequent reasons include:
- Migraines: These are intense headaches often accompanied by nausea, vomiting, and sensitivity to light or sound. Migraines involve neurological changes and chemical imbalances in the brain that trigger both headache and nausea.
- Dehydration: Not drinking enough fluids can lead to headaches and nausea.
- Low blood sugar: Skipping meals or certain health conditions can cause low blood sugar, resulting in headache and nausea.
- Common illnesses: Flu, colds, stomach infections, food poisoning, and respiratory infections can cause these symptoms.
- Stress and anxiety: Mental health factors can manifest physically as headaches with nausea.
- Excessive caffeine, nicotine, or alcohol consumption or withdrawal from these substances.
- Other potential causes include pregnancy, food allergies, medication side effects, and more serious conditions like brain infections or injuries.
If these symptoms are frequent, severe, or worsening, it is important to see a healthcare professional for proper diagnosis and treatment. Treatment depends on the cause but may include hydration, pain relief, managing stress, dietary adjustments, and specific medications for migraines or other underlying conditions.
