Migraine

What is a Migraine?

Migraine headaches can cause varying amounts of pain for the people who suffer from this condition. Migraines can last for days and the pain is often excruciating. Although the exact reasons why some people get migraines are not fully known, there are various theories, such as brain chemical imbalances and brainstem changes.

It is also believed that there are numerous circumstances that can initiate a migraine. These include fluctuating hormones in females, certain foods and beverages, stress, weather changes, specific medications and vigorous physical activity.

What are the Symptoms of a Migraine?

Before, during and after a migraine headache, individuals may feel various symptoms as they go through one or more stages.

Symptoms include

A day or two before a migraine, individuals may go through the prodrome stage which causes mood swings, a stiff neck and thirst. Individuals may experience the aura stage either before or while they are having a migraine. These symptoms include seeing spots or bursts of light, problems when talking and facial numbness.

The stage of attack, which can last up to 72 hours, may consist of throbbing head pain, light sensitivity, blurry vision and vomiting. Postdrome is the last stage and it often lasts for 24 hours. During this period, individuals may feel weak, dizzy and confused.

Migraine Causes

Environmental factors and genetics play a role in migraines, which are thought to be caused by brain chemical imbalances and changes in the brainstem. During a migraine, levels of serotonin drop causing neuropeptides to be released, resulting in migraine headaches.

There are several factors that may trigger migraines, including the following:

  • Sleep pattern disruptions, such as getting too much or too little sleep
  • Physical exertion
  • Barometric pressure and weather changes
  • Some medications such as nitroglycerin or oral contraceptives
  • Alcohol consumption
  • Consuming some foods including salty or processed foods and some cheeses
  • Hormonal changes in women, particularly when estrogen levels have dropped, during pregnancy, or after menopause
  • A drop in blood sugar

Age usually plays a factor in when migraines start. While migraines can affect persons of any age – they usually begin in adolescence and peak during your 30s.
