preventing migraine

Overview

A migraine is a type of headache that can cause intense throbbing or pulsing pain, often on one side of the head. It is a brain condition that affects how nerve signals and blood vessels work, and it can also bring other symptoms like nausea, vomiting, and sensitivity to light and sound.

Yes. Migraine is one of the most common conditions in the world. Around 1 in 7 people experiences migraine, and it affects people of all ages and backgrounds.

Anyone can get a migraine, but it is more common in women and people assigned female at birth. It often starts during the teenage years or early adulthood, though children and older adults can also be affected.

Symptoms

Common symptoms

• Throbbing or pulsing pain on one side of the head (though it can be on both sides)
• Moderate to severe pain that makes daily activities hard
• Sensitivity to light, sound, and sometimes smells
• Nausea or vomiting
• Feeling dizzy or lightheaded
• Blurred vision or seeing flashing lights (aura)

Symptoms in children

• The headache may be on both sides of the head, not just one side
• Children may feel very tired or pale
• They might have belly (tummy) pain or feel sick
• They may want to lie down in a dark, quiet room

Symptoms in older adults

• Headache may feel less severe than in younger people, but it can still be disabling
• Aura symptoms can be more confusing and may be mistaken for a stroke (temporary weakness or vision changes)
• New or different headaches in older adults should be checked by a doctor without delay

Causes

Main causes

• The exact cause isn't fully understood, but it involves abnormal activity in the brain and changes in how nerve signals pass messages
• Chemicals in the brain and the trigeminal nerve (a major nerve in the face and head) are thought to play a role
• Changes in blood flow around the brain can also be involved

Risk factors

• Family history - migraine often runs in families
• Being female or assigned female at birth
• Hormonal changes, such as around periods, pregnancy, or menopause
• Stress and anxiety
• Poor sleep or changes in sleep routine
• Certain foods or drinks, like alcohol, chocolate, aged cheese, and caffeine (though triggers vary)
• Skipping meals or going too long without food
• Some medicines can trigger headaches in some people

When to see a doctor

See a doctor urgently if:

• Headache with a fever, stiff neck, or a rash
• Headache that starts suddenly and is extremely severe
• Weakness, numbness, or speech problems
• Headache after a head injury

Book a routine appointment if:

• You have frequent headaches (for example, more than once a week)
• Your headaches are stopping you from doing everyday tasks
• You need pain relief most days or are worried about how much medication you use
• You think you might be experiencing migraine and want a clear plan

Diagnosis

A doctor will usually diagnose migraine by listening to your story and asking about your symptoms, family history, and triggers. Most people do not need tests. The doctor will also check that something else isn't causing the headaches.

Tests that may be done

• No specific test is needed for most people
• Sometimes, if the doctor is unsure, they may recommend a brain scan (like an MRI) to rule out other causes
• Keeping a headache diary is a simple test you can do yourself - note when headaches happen, how long they last, what you ate, and how you slept

What to expect at your appointment

Your doctor may ask you to keep a headache diary for a few weeks. They may ask about your sleep, stress, diet, and any medicines you use. This helps them understand your migraine pattern and build a plan with you.

Treatment

There are two main goals: stopping a migraine attack when it happens, and preventing attacks from occurring in the first place. Treatment is very individual - what works for one person may not work for another.

Self-care at home

• Rest in a dark, quiet room when a headache starts
• Apply a cold or warm cloth to your forehead or neck (whichever feels better)
• Drink water regularly and sip slowly
• Avoid bright screens and strong smells
• Identify and avoid your own triggers by keeping a headache diary
• Manage stress with breathing exercises, meditation, or gentle movement

Medical treatments

Doctors may suggest pain-relief medicine for migraine attacks, but it's important to take it early as directed. They may also recommend prescription medicines to prevent migraines if they happen often. These are taken regularly, not just during an attack. Always discuss the options with your doctor - do not start or stop any medicine without their advice.

Living with this condition

You can live well with migraine by building a daily routine that supports your brain - regular sleep, regular meals, and time for rest. It helps to learn what your warning signs are and to have a plan ready, such as carrying water and sunglasses, and telling people around you what you need.

Lifestyle tips

• Keep a consistent sleep schedule, even on weekends
• Eat meals at regular times and stay hydrated
• Limit caffeine and alcohol to find what your body tolerates
• Take breaks from screens and stretch regularly
• Build daily physical activity into your routine, like walking or swimming
• Learn relaxation techniques like deep breathing or progressive muscle relaxation

Diet and exercise

No single diet prevents migraine in everyone, but eating regular, balanced meals helps. Some people notice specific foods trigger attacks - keeping a food diary can reveal these. Regular aerobic exercise (like brisk walking, cycling, or swimming) can reduce the frequency and severity of headaches for many people. Start slowly and check with your doctor before beginning a new exercise plan.

Mental health and emotional wellbeing

Living with migraine can be frustrating and worrying, especially if attacks are frequent. It's normal to feel anxious or low. It can help to talk to a counsellor or psychologist, and to connect with others who understand. Your mental health matters just as much as your physical health.

Prevention

Migraine cannot always be fully prevented, but for most people the frequency and severity of attacks can be significantly reduced. The key is to identify your triggers and to work with your doctor to find a prevention plan that works for you. Some people only need lifestyle changes; others benefit from regular preventive medicine.

Complications

If left untreated

• Migraine itself is rarely dangerous, but frequent attacks can seriously affect quality of life, work, school, and relationships
• Using pain-relief medicine too often can actually cause more headaches (medication-overuse headache)
• Rarely, a very unusual type of migraine (called a hemiplegic migraine) can cause temporary weakness on one side of the body - this needs medical attention

Long-term outlook

Migraine can be stubborn, but the outlook is very positive for people who seek help. With a good understanding of your own patterns, the right support, and an effective treatment plan, most people learn to control their migraines and lead full, active lives. You are not facing this alone.
