Frequent Migraines Eating Fatty Fish May Offer Comfort

Overview

A migraine is a type of headache problem that comes back again and again. A migraine attack is usually a throbbing pain, often on one side of the head, and it can last from a few hours to a few days. Many people also feel sick, and light or sound can feel unbearable. Migraine is a real medical condition, not just a 'bad headache'. Recent research has looked at whether eating more oily fish, such as salmon, mackerel and sardines, might help some people have fewer or less painful attacks. The idea is that the special fats in oily fish (called omega-3 fats) may calm some of the inflammation and nerve activity linked to migraine. This is promising but still early evidence. It is not a cure, and it does not replace advice from your doctor.

Yes. Migraine is very common. Health experts estimate that around 1 in 7 adults around the world get migraine, and it is one of the top reasons people miss work or school.

Migraine can affect anyone, at any age. It is about three times more common in women than in men, often starting in the teenage years or the twenties and easing later in life. Children get migraine too, sometimes with mostly tummy upset rather than head pain. Some people notice attacks linked to hormonal changes, such as monthly periods or the menopause.

Symptoms

Common symptoms

• Throbbing or pulsing headache, often on one side of the head, but sometimes on both sides
• Pain that gets worse when you move, bend, cough or climb stairs
• Feeling sick or being sick
• Sensitivity to light, sound or smells, so you want to lie down in a dark, quiet room
• An 'aura' in some people: flashing lights, zig-zag lines, blind spots, or tingling and numbness that slowly spreads, usually before the headache
• Feeling tired, irritable, hungry or thirsty in the hours before an attack
• Attacks lasting from a few hours up to three days

Symptoms in children

• Attacks may be shorter than in adults and the head pain may be on both sides or at the front
• Tummy pain, nausea and vomiting can be the main problem, sometimes with little or no headache
• Dizziness, pale skin and needing to sleep
• Young children may not describe 'headache' but may be clingy, irritable, go quiet, or refuse to play or eat
• Children often need to rest in a dark, quiet room and may fall asleep and wake up feeling better

Symptoms in older adults

• A first migraine after the age of 50 is less common and should always be checked by a doctor
• Aura without headache (visual or sensory changes with no head pain) can become more noticeable with age
• Migraine symptoms can be confused with other conditions, so careful assessment matters
• Other health problems and other medicines can change which treatments are safe, so review your plan with your doctor regularly
• Taking pain relief very often can cause 'medication overuse headache', which is more of a risk in older adults with long-standing headache

Causes

Main causes

• Migraine is not fully understood, but it runs in families and involves the way the brain and nerves process signals
• The trigeminal nerve, a large nerve in the head, and changes in blood vessels around the brain are involved in attacks
• Chemicals in the brain, such as serotonin, affect how attacks start and how pain is felt
• Certain foods, alcohol (especially red wine), caffeine, skipped meals, dehydration, poor sleep, stress and hormonal changes can trigger attacks in some people
• Weather changes, bright or flickering light, strong smells and loud noise can be triggers for some
• In some people, the body's inflammatory response may play a part, which is one reason researchers are looking at omega-3 fats from fish as a possible support

Risk factors

• A close family member with migraine
• Being female, especially with hormonal triggers such as periods
• Being in your teens to forties, when migraine is most common
• High or ongoing stress, anxiety or depression
• Sleep problems, shift work or irregular sleep
• Skipping meals and not drinking enough water
• Obesity and low levels of physical activity
• Taking pain relief very often, which can make headaches more frequent
• Drinking a lot of caffeine or alcohol

When to see a doctor

See a doctor urgently if:

• You get a sudden, extremely severe headache — call your local emergency number straight away
• You have headache with fever, a stiff neck, confusion, weakness, speech problems or a seizure — call your local emergency number
• Your headache pattern changes clearly, or headaches keep getting worse
• You have a first-ever migraine after age 50
• You need pain relief on most days

Book a routine appointment if:

• You think you may have migraine but have not been diagnosed
• Headaches are affecting work, school, sleep or family life
• Your usual treatment is not working well or you need it too often
• You want to talk about diet changes, including eating more oily fish, and whether that is safe for you
• You are pregnant, planning a pregnancy or breastfeeding and want to review your headache plan
• You have other health conditions, allergies or take other medicines

Diagnosis

There is no single test for migraine. A doctor usually makes the diagnosis by listening carefully to your story: what the pain feels like, where it is, how long it lasts, what else happens (like nausea or light sensitivity), and what seems to set it off. They will also ask about your health, medicines and family history, and check you over. A headache diary is often very helpful.

Tests that may be done

• A headache diary: recording when attacks happen, how long they last, what you ate, how you slept, and what helped
• A physical and neurological examination, checking your eyes, strength, sensation, coordination and reflexes
• Blood tests sometimes, to look for other causes such as thyroid or vitamin problems
• A scan of the brain (such as CT or MRI) is not needed for typical migraine — it is only arranged if there are warning signs or the pattern is unusual
• Eye checks or other tests if your symptoms suggest another cause

What to expect at your appointment

Your appointment will mostly be a conversation. Be ready to describe your attacks and bring your diary if you keep one. Your doctor may ask about stress, sleep, diet and hormonal cycles. If your headaches fit a clear migraine pattern and your examination is normal, you may not need any scans. You may be offered a treatment plan to try and a follow-up to see how it works. Bringing a list of all your medicines and supplements helps your doctor keep you safe.

Treatment

Migraine care usually has three parts. First, treat attacks early with pain relief that suits you. Second, reduce the number of attacks with daily habits and, if needed, preventive treatment from your doctor. Third, look at triggers, including diet. Eating more oily fish may be one helpful piece of a healthy eating pattern, but it works best alongside the rest of your plan. Every person is different, so your doctor or pharmacist will help you find what works for you.

Self-care at home

• At the first sign of an attack, rest in a quiet, darkened room and try to sleep if you can
• Keep a headache diary to spot patterns and triggers
• Eat regular meals and drink water through the day — skipping meals and dehydration are common triggers
• Keep regular sleep and wake times, including at weekends
• Manage stress with simple tools such as slow breathing, gentle walking, or a relaxation or mindfulness app
• Limit alcohol and caffeine, and avoid sudden caffeine changes
• Try to stay gently active between attacks, building up slowly
• Use a cool pack or warm pack on your head or neck if that helps you
• Review pain relief with your pharmacist so you do not use it too often

Medical treatments

Doctors treat migraine in two main ways. Attack treatment aims to stop a headache that has already started — for example, simple pain relievers that your pharmacist or doctor recommends, and other prescription options for people whose attacks do not settle. Preventive treatment aims to make attacks less frequent or less severe; it is usually considered when attacks are frequent or very disruptive. Preventive options include medicines that were first developed for other conditions, such as blood pressure medicines, certain antidepressant medicines and certain anti-seizure medicines, as well as newer treatments designed specifically for migraine. Some people are taught special calming or biofeedback techniques. Your doctor will choose based on your health, other medicines, pregnancy plans and what suits you. Never start, stop or change a medicine without talking to your healthcare provider first.

When is surgery considered?

Surgery is not a standard treatment for migraine. In rare cases, specialists may discuss procedures for very specific headache conditions, but this is not part of usual migraine care.

Living with this condition

Life with frequent migraine means planning a little more than other people might. Many people find a routine helps: regular meals, water, sleep and gentle exercise, plus knowing where their pain relief is and having a quiet place to rest at work or school. Keep your headache diary up to date and bring it to appointments. Tell your family, friends, teachers or employer what helps when an attack starts, so they can support you.

Lifestyle tips

• Aim for a steady daily routine — the same sleep and meal times each day
• Build gentle, regular movement into your week, such as walking, swimming or cycling
• Keep alcohol and caffeine moderate and consistent
• Take screen breaks, and adjust bright or flickering light where you can
• Learn your early warning signs so you can act fast
• Carry water and a snack when you go out
• Ask about support at work or school, such as breaks or a quieter space during an attack

Diet and exercise

A balanced diet supports migraine care. Health advice in the UK suggests eating at least two portions of fish a week, one of them oily — for example salmon, mackerel, sardines, herring or trout. These are rich in omega-3 fats, the nutrient researchers are looking at for migraine. If you eat fish, this is a sensible, food-first way to try it. Some people need to be careful: if you have a fish allergy, avoid fish completely; if you are pregnant or breastfeeding, there is guidance on limiting certain fish (such as shark, swordfish and marlin) because of mercury; and if you have kidney or heart conditions, ask your doctor first. Plant sources of omega-3 include flaxseed, chia seeds, walnuts and rapeseed oil, and some foods are fortified. Do not take fish oil supplements without checking with your pharmacist or doctor, because they can interact with medicines such as blood thinners. For exercise, choose something you enjoy and build up slowly. Regular, moderate activity may help reduce how often attacks happen, but very intense exercise can trigger an attack in some people.

Mental health and emotional wellbeing

Living with frequent pain is tiring, and it is very common to feel anxious, low or frustrated. Migraine and low mood can feed each other — stress can trigger attacks, and attacks can add stress. This is not a sign of weakness, and help is available. Talk to your doctor or nurse about how you are feeling; talking therapies and stress-management approaches can help both mood and migraine. If you ever feel unable to cope or have thoughts of harming yourself, please reach out for crisis support straight away — contact your local emergency number or a local crisis line, or speak to a trusted person who can stay with you while you get help.

Prevention

Migraine cannot always be prevented, but the number and severity of attacks can often be reduced. Regular meals, steady sleep, hydration, stress care and regular gentle exercise all help. Avoiding your personal triggers helps too — but try not to cut out lots of foods at once, as that can make eating stressful and hard to keep up. If attacks remain frequent, your doctor may suggest preventive treatment. Diet changes such as eating more oily fish are being studied and may help some people, but they are not a guaranteed prevention.

Screening programmes

There is no screening test for migraine. If migraines run in your family or you have frequent headaches, it is worth talking to your doctor early, rather than waiting. If you have other health conditions such as high blood pressure, diabetes or a history of stroke, keeping those well managed is also part of protecting your long-term brain and blood vessel health.

Complications

If left untreated

• Attacks may become more frequent over time, sometimes turning into a long-term daily headache pattern
• Medication overuse headache, caused by taking pain relief too often
• Missed work, school or study, and money worries from time off
• Sleep problems, which can then trigger more attacks
• Anxiety, low mood and feeling isolated
• Rarely, a very long or severe attack (sometimes called status migrainosus) that needs urgent medical care
• People with migraine with aura have a small increase in stroke risk, so it is especially important to manage other risk factors such as smoking, high blood pressure and diabetes with your doctor

Long-term outlook

The outlook is generally hopeful. Many people find that with a good plan — regular habits, a treatment approach that suits them, and support from their healthcare team — attacks become less frequent and easier to manage. Research into diet, including the possible role of omega-3 fats from oily fish, is adding to what we know, and new treatments continue to be developed. Migraine is a long-term condition for many people, but it can be lived with well, and you deserve good support along the way.
