Qual é a causa das enxaquecas?

Factors that jointly contribute to beginning the cascade of reactions called migraine are known as triggers. Triggers can be anything from sleep pattern changes, certain foods and substances, hormone levels, weather changes, and sensory overload (strong sunlight, perfume.) The point where the migraine starts is the trigger threshold.

The farther beyond your threshold you go, the more severe your symptoms become. Once the system gets going it is tough to know how long the related symptoms will last, even after triggers are reduced. Keeping trigger amounts over one’s tolerance levels on a regular basis might be a significant contributing factor to chronic headache and migraine symptoms. How Does This Work? Here’s an analogy: Think of your body’s tolerance for triggers such as clear glass measuring cup or a chemistry beaker.

The glass can be stuffed various different colored marbles – each colour represents a different cause. The obvious cup can only hold a lot of marbles. You may fill it entirely with a single colour marbles or a variety. It does not matter. All that matters is that if the glass gets complete – the migraine process starts. How complete your glass is as a starting point may differ from day to day and sometimes is completely out of your control.


If hormones and weather changes are trigger variables for you, then sometimes you may begin the day out with your own glass partly full without doing anything in any way. This explains why sometimes eating a little chocolate or sleeping in may cause a migraine and other times not. Reactions to triggers in addition to tolerance thresholds are different from person to person. Some people are extremely sensitive overall and others aren’t.

What is a cause for one person might not be for another. All these variables make controlling headaches and migraines really tricky for physicians and the medical community that prefer”one size fits all” remedies. Can you truly prevent headache and migraine attacks by avoiding triggers? Many individuals have had good success with treating their illness with trigger avoidance.


However, there’ll always be some individuals who won’t be able to experience relief from their symptoms using those techniques. You might be so sensitive that you have many causes and even the smallest quantity of exposure may affect you. You might have difficulty determining exactly what your triggers are as some like weather and food will provoke a delayed response of between two hours and three times. Your triggers may not cause migraines independently but rather in conjunction with other causes – making them more difficult to spot.
