Why do I always have a headache?

Headache is a common symptom of many underlying conditions. While you may feel the pain in one area of your head, the source may be in another. For example, sinus headaches often feel like they're located behind the eyes, while tension headaches can be felt all over the head.

Dehydration

Not drinking enough water can cause headaches, especially if you're dehydrated for a long period.

Skipping meals

When you don't eat for too long, your blood sugar levels drop, which can lead to headaches.

Lack of sleep

Not getting enough sleep can cause tension headaches the next day.

Too much sleep

On the flip side, sleeping too much can also cause headaches.

Stress

Both physical and emotional stress can trigger headaches.

Caffeine

Having too much caffeine can cause headaches, while suddenly going without caffeine can also cause them.

Alcohol

Drinking alcohol, especially in large amounts, can lead to headaches.

Sinus problems

Inflammation of the sinuses, called sinusitis, can put pressure on the head, causing pain and headaches.

Hormonal changes

For women, hormonal changes related to menstruation, pregnancy, and menopause can all trigger headaches.

Medications

Some medications can also have headaches as a side effect, such as antihistamines, decongestants, and birth control pills.

Underlying medical conditions

In some cases, headaches can be a sign of a more serious underlying medical condition, such as:

- High blood pressure

- Anemia

- Diabetes

- Thyroid problems

- Brain tumor

- Meningitis

If you have frequent or severe headaches, it's important to see a doctor to determine the cause and get proper treatment.
