Finding your migraine triggers

July 5, 2016 by Tammy Rome Migraine, Self-Care 0 comments

I promised you more details about migraine triggers. So, after a little break to spend some time with my family, I’m back and ready to go.

Migraine attacks actually begin several hours (if not days) before the headache phase starts. Many people mistake prodrome symptoms for triggers. It’s an easy mistake to make. For example, I sometimes hear people say, “Every time I eat chocolate, I get a migraine [attack] within minutes.”

Most “triggers” are actually prodrome symptoms

There’s actually very little evidence to support the idea of chocolate as a trigger. In fact, the evidence for food triggers is getting weaker every year. Because an attack begins many hours before we feel its effects, it’s pretty unlikely that something we ate would trigger a migraine within minutes. A more likely explanation is that cravings for chocolate (or anything else!) are part of the prodrome, during which time the attack is already underway and the headache phase is inevitable^*.

Prodrome

A 2015 study³ attempted to determine the difference between prodrome symptoms and true triggers. They identified prodrome symptoms as those occurring within a 2-hour window prior to the onset of pain. A total of 24 different symptoms were identified:

red or pale face
cold hands or feet
body chills
osmophobia (painful sensitivity to smells)
phonophobia (painful sensitivity to sound)
photophobia (painful sensitivity to light)
back pain
other aches & pains
neck tension
sleep disturbances
yawning
bad mood
irritability
hyperactivity
apathy
depressed mood
fatigue
difficulty speaking
exhaustion
forgetfulness
difficulty concentrating
vertigo
nausea
diarrhea
lack of appetite
excessive thirst
food cravings

Triggers

That same study examined these possible triggers:

food
stress
relief from stress
weather changes
bright sunlight
flickering light
heat
cold
exercise
sexual activity
skipping/irregular meals
dehydration
lack of or excessive sleep
holidays
alcohol
strong odors
medications
hormonal changes
illness

How do you tell the difference?

There is some overlap on those two lists. Sometimes it’s no so easy to know if something is a trigger or just part of the prodrome. Through trial and error, I have discovered that my prodrome phase can last more than a day. So, any symptom I experience 24 hours prior to the start of the headache phase, I count as prodrome. That’s how I discovered that most foods I thought were triggers were actually just prodrome food cravings. There was one exception: salty foods. Because they have the potential to cause dehydration, I now make sure to drink plenty of water when I eat salty foods. The trigger wasn’t the food, but dehydration.

Your triggers and prodrome symptoms will be different than mine. The best way to identify your triggers is to keep a detailed record of your attack frequency, duration in connection with possible triggers. Over time, you will begin to see a pattern emerge. From that information, you will be able to predict the likelihood of your next attack. There will be some triggers that are easier to avoid than others. Eliminating a trigger may require you to change some bad habits — like skipping meals or staying up late. You may need to educate loved ones, too.

To help you discover your unique pattern of prodrome symptoms and triggers, I have created a Migraine Tracker. Feel free to download either version and use as needed. What you discover can help you and your doctor adjust your treatment plan to minimize the number of attacks you experience.
