Common Causes of Headaches and When to See a Doctor

Headaches are common and can happen for many reasons. Dehydration, stress, poor sleep, eye strain, and hunger are frequent triggers. Migraines may cause severe pain, nausea, and sensitivity to light. Sinus infections can also create pressure headaches. Most headaches improve with rest, hydration, and pain relief medication. However, sudden severe headaches, headaches after injury, vision changes, weakness, or repeated vomiting require urgent medical attention. Keeping a headache diary may help identify triggers such as certain foods or lack of sleep. Reducing stress and maintaining regular sleep habits often decreases headache frequency. If headaches happen regularly, consult a healthcare professional for diagnosis and treatment.
