user: What are the symptoms and causes of migraine headaches?

assistant: The symptoms of migraine headaches include an intense throbbing pain in the head, normally on one side of the head, and can be accompanied by nausea, vomiting and loose bowels movements. Some sufferers report impairment to vision either before or during the headache, described as an aura effect, and as such extreme sensitivity to light can be a common symptom.

The causes of migraine headaches are harder to define, and harder as a result to treat. Most medical professionals agree that the causes of migraines are unknown, however there are a number of triggers that can set off a migraine in sufferers. These include dietary triggers such as dehydration, coffee, alcohol and many others. Hormonal changes can also be a trigger, so many women are impacted during their menstrual cycle. Other triggers such as stress and emotional anguish can also cause the onset of migraines. Environmental factors such as bright or flickering lights can also be a trigger.

For most sufferers, rest and non-prescription painkillers such as ibuprofen are sufficient to recover from a headache, but more extreme cases may require a visit to a GP and prescription of triptans to alleviate the symptoms. Other treatments include acupuncture and transcranial stimulation, but ideally understanding and avoiding personal trigger factors is the preferred method.
