What Causes Headache? Common Causes and When to See a Doctor

Headaches are one of the most common health complaints. They can feel like pressure, throbbing, aching or sharp pain and may affect one or both sides of the head.

Most headaches are not caused by a serious medical condition. However, headaches that are frequent, severe, worsening or different from your usual pattern should be evaluated by a healthcare professional. 

Common Causes of Headache

There are many possible causes of headaches. Common triggers and causes include:

1. Stress

Stress can trigger or worsen headaches, particularly tension-type headaches. Muscle tension around the head, neck and shoulders may also contribute to discomfort. 

2. Dehydration

Not drinking enough fluids can contribute to headaches. Staying adequately hydrated throughout the day may help prevent headaches related to dehydration. 

3. Lack of Sleep

Changes in your normal sleep pattern or not getting enough sleep may trigger headaches in some people.

Maintaining a regular sleep schedule can support overall health and may help reduce some headache triggers.

4. Skipping Meals

Going too long without eating can trigger headaches for some people. Regular, balanced meals can help reduce headaches associated with missed meals. 

5. Eye Strain

Long periods of screen use or uncorrected vision problems may contribute to headaches in some people.

Taking regular screen breaks and having your eyesight checked when needed may help.

6. Poor Posture

Poor posture can place extra tension on the neck, shoulders and upper back. This may contribute to certain types of headaches. 

7. Cold, Flu and Other Illnesses

Headaches can occur along with illnesses such as colds and flu. They may also occur with fever or congestion.

If your symptoms are severe, persistent or getting worse, consult a healthcare professional.

8. Migraine

Migraine is a neurological condition that can cause moderate to severe headache. A migraine may involve throbbing or pulsing pain and can be accompanied by nausea and sensitivity to light or sound. 

9. Hormonal Changes

Some people experience headaches associated with hormonal changes, including around menstruation or menopause. 

10. Frequent Use of Pain Medicines

Using pain-relief medicines too frequently can contribute to medication-overuse headaches. If you regularly need medication for headaches, speak with a healthcare professional about your symptoms and treatment options. 

Common Types of Headaches

Headaches can have different patterns and causes.

Tension Headaches

Tension-type headaches are common and may feel like pressure or tightening around the head. Stress and muscle tension can contribute to this type of headache.

Migraine

Migraine can cause moderate to severe pain and may be associated with nausea, vomiting or increased sensitivity to light and sound. 

Cluster Headaches

Cluster headaches are less common but can cause intense pain, often around or behind one eye.

Secondary Headaches

A secondary headache happens when another medical condition or factor is responsible for the headache. Some secondary headaches require urgent medical assessment.

When Should You See a Doctor for a Headache?

Consider making an appointment with a healthcare professional if:

  • You regularly experience headaches.
  • Your headaches are becoming more frequent.
  • Your headaches are becoming more severe.
  • Your usual headache pattern changes.
  • Headaches interfere with work, sleep or daily activities.
  • Your headaches are not improving with appropriate self-care.

When Is a Headache a Medical Emergency?

Some headache symptoms require immediate medical attention.

Seek emergency medical care if a headache:

  • Starts suddenly and is extremely severe.
  • Is the worst or most severe headache you have experienced.
  • Occurs with weakness or numbness.
  • Causes difficulty speaking or understanding speech.
  • Causes difficulty walking or maintaining balance.
  • Occurs with confusion or loss of consciousness.
  • Occurs with a seizure.
  • Is accompanied by significant vision changes.
  • Occurs with a high fever and stiff neck.
  • Develops after a significant head injury. 

A sudden, extremely severe headache can sometimes be a sign of a serious medical condition and should not be ignored. 

What Can Help With a Mild Headache?

For a mild headache without warning signs, some general measures may help:

  • Drink enough water.
  • Get adequate rest.
  • Avoid skipping meals.
  • Take regular breaks from prolonged screen use.
  • Try to reduce stress.
  • Maintain a consistent sleep routine.
  • Keep track of possible headache triggers.

If headaches continue or become more frequent, consult a healthcare professional. 

How Can You Track Your Headaches?

If you experience headaches regularly, keeping a headache diary can help identify patterns and provide useful information for your doctor.

You can record:

  • Date and time the headache started
  • How long it lasted
  • Location of the pain
  • Severity of the pain
  • Food and drinks consumed
  • Sleep duration
  • Stress or possible triggers
  • Other symptoms
  • Any medicines taken

A headache diary can make it easier to discuss recurring headaches during a medical consultation. 

Which Doctor Should I See for Headaches?

If you are experiencing a new, recurring or unexplained headache, a General Physician can often be a good starting point.

Depending on your symptoms and medical evaluation, you may be referred to a Neurologist or another appropriate specialist.

You do not always need to determine the exact cause or specialist yourself. A healthcare professional can guide you based on your symptoms and medical history.
