What is a migraine?

A migraine is an episode of moderate to severe throbbing or pulsating pain, usually on one side of the head. It is accompanied by light and sound sensitivity, and it may cause nausea and vomiting. Symptoms from a migraine can last hours to even days. Migraines are three times more common in women than men.

Symptoms of a migraine:

  • Throbbing or pulsing pain on one or both sides of your head.
  • Sensitivity to light, sounds, and sometimes smell and touch.
  • Lightheadedness.
  • Nausea and vomiting.
  • Blurred vision

Causes of a migraine:

It was widely believed that migraines were caused by opening and narrowing of blood vessels in the head. However, most doctors now link the cause to genes that control the activity of some brain cells. Things that may trigger a migraine include:

  • Stress.
  • Anxiety.
  • Exposure to light and other stimuli.
  • Lack of food or sleep.
  • Hormonal changes (in women).
  • Medication.
  • Consumption of certain foods and food additives.
