Identifying And Avoiding Migraine Triggers

Overview Of Identifying And Avoiding Migraine Triggers

A migraine is a type of headache. It may occur with symptoms such as nausea, vomiting, or sensitivity to light and sound. In many people, a throbbing pain is felt only on one side of the head. Identifying your migraine triggers can help you avoid these headaches in the future.

Identifying And Avoiding Migraine Triggers

A migraine headache is caused by abnormal brain activity. This activity can be triggered by many things. But the exact chain of events remains unclear. Most medical experts believe the attack begins in the brain and involves nerve pathways and chemicals. The changes affect blood flow in the brain and surrounding tissues. Migraine headaches tend to first appear between the ages of 10 and 45. Sometimes, they begin earlier or later. Migraines may run in families. Migraines occur more often in women than men. Some women, but not all, have fewer migraines when they are pregnant.

Migraine attacks may be triggered by any of the following:

• Caffeine withdrawal
• Changes in hormone levels during a woman’s menstrual cycle or with the use of birth control pills
• Changes in sleep patterns, such as not getting enough sleep
• Drinking alcohol
• Exercise or other physical stress
• Loud noises or bright lights
• Missed meals
• Odors or perfumes
• Smoking or exposure to smoke
• Stress and anxiety

Migraines can also be triggered by certain foods. The most common are:

• Chocolate
• Dairy foods, especially certain cheeses
• Foods with monosodium glutamate (MSG)
• Foods with tyramine, which includes red wine, aged cheese, smoked fish, chicken livers, figs, and certain beans
• Fruits (avocado, banana, citrus fruit)
• Meats containing nitrates (bacon, hot dogs, salami, cured meats)
• Onions
• Peanuts and other nuts and seeds
• Processed, fermented, pickled, or marinated foods
• True migraine headaches are not a result of a brain tumor or other serious medical problem. Only a health care provider who specializes in headaches can determine if your symptoms are due to a migraine or other condition.

Symptoms Of Migraines

There are two main types of migraines:

• Migraine with aura (classic migraine)
• Migraine without aura (common migraine)

An aura is a group of nervous system (neurologic) symptoms. These symptoms are considered a warning sign that a migraine is coming.

Most often, the vision is affected and can include any or all of the following:

• Temporary blind spots or colored spots
• Blurred vision
• Eye pain
• Seeing stars, zigzag lines, or flashing lights
• Tunnel vision (only able to see objects close to the center of the field of view)
• Other nervous system symptoms include yawning, difficulty concentrating, nausea, trouble finding the right words, dizziness, weakness, numbness, and tingling. Some of these symptoms are much less common with migraine headaches. If you have any of these symptoms, your provider will likely order tests to find the cause.

An aura often occurs 10 to 15 minutes before the headache but can occur just a few minutes to 24 hours before. A headache does not always follow an aura.

The headaches usually:

• Start as a dull ache and get worse within minutes to hours
• Are throbbing, pounding, or pulsating
• Are worse on one side of the head with pain behind the eye or in the back of the head and neck
• Last 4 to 72 hours

Other symptoms that may occur with the headache include:

• Chills
• Increased urination
• Fatigue
• Loss of appetite
• Nausea and vomiting
• Sensitivity to light or sound
• Sweating

Symptoms may linger, even after the migraine goes away. This is called a migraine hangover. Symptoms can include:

• Feeling mentally dull, like your thinking is not clear or sharp
• Needing more sleep
• Neck pain

Exams & Tests

Your provider can diagnose migraine headache by asking about your symptoms and family history of migraines. A complete physical exam will be done to determine if your headaches are due to muscle tension, sinus problems, or a brain disorder.

There is no specific test to prove that your headache is actually a migraine. In most cases, no special tests are needed. Your provider may order a brain CT or MRI scan if you have never had one before. The test may also be ordered if you have unusual symptoms with your migraine, including weakness, memory problems, or loss of alertness.

An EEG may be needed to rule out seizures. A lumbar puncture (spinal tap) might be done.

Treatment Of Migraines

There is no specific cure for migraine headaches. The goal is to treat your migraine symptoms right away, and to prevent symptoms by identifying and avoiding your triggers.

A key step is learning how to manage your migraines at home. A headache diary can help you identify your headache triggers. Then you and your provider can plan how to avoid these triggers.

Lifestyle changes include:

• Better sleep habits, such as getting enough sleep and going to bed at the same time each night
• Better eating habits, including not skipping meals and avoiding your food triggers
• Managing stress
• Losing weight, if you’re overweight
• If you have frequent migraines, your provider may prescribe medicine to reduce the number of attacks. You need to take the medicine every day for it to be effective.

Medicines may include:

• Antidepressants
• Blood pressure medicines, such as beta-blockers
• Anti-seizure medicines
• Calcitonin gene-related peptide agents
• Botulinum toxin type A (Botox) injections may also help reduce migraine attacks if they occur more than 15 days a month.

Some people find relief with minerals and vitamins. Check with your provider to see if riboflavin or magnesium is right for you.

TREATING AN ATTACK

Other medicines are taken at the first sign of a migraine attack. Over-the-counter (OTC) pain medicines, such as acetaminophen, ibuprofen, or aspirin are often helpful when your migraine is mild.

Be aware that:

• Taking medicines more than 3 days a week may lead to rebound headaches. These are headaches that keep coming back due to overuse of pain medicine.
• Taking too much acetaminophen can damage your liver.
• Too much ibuprofen or aspirin can irritate your stomach or kidneys.
• If these treatments do not help, ask your provider about prescription medicines. These include nasal sprays, suppositories, or injections. The group of medicines most often used is called triptans.
• Some migraine medicines narrow the blood vessels. If you are at risk of having a heart attack or have heart disease, talk with your provider before using these medicines. Some migraine medicines should not be used by pregnant women. Talk with your provider about which medicine is right for you if you are pregnant or planning to become pregnant.
• Other medicines treat symptoms of migraine, such as nausea and vomiting. They may be used alone or along with the other drugs that treat the migraine itself.
• Feverfew is an herb for migraines. It can be effective for some people. Before using feverfew, make sure your provider approves. Herbal remedies sold in drugstores and health food stores are not regulated. Work with a trained herbalist when selecting herbs.

PREVENTING MIGRAINE HEADACHES

If your migraines occur more than twice a week despite the use of triptans, your provider may place you on medicines to take every day, which may help prevent your migraines. The goal is to prevent how often migraines occur and how severe the headache is.

These types of medicines may help prevent or reduce migraine headaches:

• Medicines commonly used for high blood pressure,(such as beta-blockers, angiotensin blockade agents, and calcium channel blockers)
• Certain medicines used to treat depression
• Certain medicines used to treat seizures, called anticonvulsants
• Botulinum toxin type A injections for select patients
• Newer devices that provide different kinds of nerve stimulation or magnetic stimulation are also being evaluated for the treatment of migraine headaches. Their exact role in treating migraines remains unclear.
