Dr Safiya Ojo, a medical practitioner with the Wuse General Hospital, on Wednesday, said that stress, fatigue, genetic and environmental factors could trigger a re-occurring migraine.
Ojo made this disclosure in an interview with the News Agency of Nigeria (NAN) in Abuja.
According to him, migraine is a primary headache disorder, characterised by recurrent headache that can be moderate or severe.
“Migraine is a primary kind of headache, which is not due to infection or cancer in the brain or any illness at all.
“Some family members have migraine, which is a genetic factor, some people, when they are stressed, have migraine, for some others, it can be due to pregnancy,’’ she said.
Ojo said the headache, which affects one half of the head, can be pulsating in nature and may last from two to 72 hours.
The medical practitioner said some common symptoms may include, nausea, vomiting, and sensitivity to light, sound, or smell, adding that the pain could be made worse by physical activity.
“Some migraine could be due to environmental factor, a person who has migraine needs to calm down and take a lot of water with a pain reliever to prevent repeated attacks.
” Changing hormone levels may also play a role in migraine. The risk usually decreases during pregnancy and the underlying mechanism is not known, she said.
Ojo said that migraine was believed to involve the nerves and blood vessels of the brain.
She said a number of medications such as simple paracetamol, could prevent attacks, depending on what works for individuals.
Ojo said that lifestyle changes were key in the recovery of migraines, adding that the pains of migraine could be disturbing.
She, however, advised Nigerians to avoid anything that could stress them or any form of activity that could trigger migraine.
