The precise underlying causes of migraines remain incompletely understood; however, a combination of genetic factors, environmental influences, and imbalances in brain chemicals like serotonin are believed to contribute to their occurrence.
While migraines are not classified as a strictly inherited condition, they often cluster within families. Consequently, if you have one or more close relatives with a history of migraines, you may have a higher likelihood of developing migraines as well.
Certain individuals associate their migraine attacks with specific triggers, which can encompass:
- Hormonal changes – such as those occurring during pregnancy, menopause, menstrual cycle alterations, or hormonal treatments like contraception.
Stress or anxiety – with approximately 80% of migraines being triggered by stress at work or home. - Fatigue (tiredness) – resulting from physical exertion, lack of sleep, or jet lag.
- Beverages – particularly alcohol (especially wine) and caffeine.
- Foods and food additives – including salty processed foods, monosodium glutamate (MSG), and the sweetener Aspartame.
- Low blood sugar – often brought on by skipping meals or fasting.
Dehydration. - Environmental factors – such as exposure to strong smells, bright lights, or loud noises.
It is crucial to recognize that these triggers can vary significantly between individuals. If you identify specific triggers that seem to initiate your migraines, it is advisable to make a conscious effort to avoid them whenever possible.
