Which factors are known to trigger Migraine headaches?

Answer generated on June 4, 2024

The AI-generated responses are for illustration purposes only and should not be used for medical purposes.

Migraine headaches can be triggered by stress, fatigue, sleep disturbances, certain foods and additives, alcohol, caffeine, environmental factors, physical activity, weather changes, high altitude, hormonal changes, and skipping meals.[1-3]

  • Stress and fatigue are common triggers that can precipitate migraine episodes by affecting the nervous system.[1]

  • Irregular sleep patterns or sleep disorders can trigger migraines, emphasizing the importance of regular sleep schedules.[1]

  • Specific foods and additives such as chocolate, cheese, monosodium glutamate, nuts, and artificial sweeteners are known to trigger migraines in susceptible individuals.[1-2]

  • Environmental factors like strong odors, noise, and flickering lights can initiate migraine attacks.[1]

  • Hormonal changes related to menstruation and ovulation can also increase the frequency of migraines, particularly in women.[1][4]

Additional info

When considering the management of migraine triggers, it is crucial to tailor strategies to individual patients, as triggers can vary widely among individuals. Lifestyle modifications, such as maintaining a regular sleep schedule, managing stress through relaxation techniques or therapy, and keeping a food diary to identify and avoid specific dietary triggers, can be effective in reducing the frequency and severity of migraines. Additionally, educating patients about the potential impact of environmental factors and advising them on ways to minimize exposure can be beneficial. For women who experience migraines related to their menstrual cycle, discussing hormonal therapies or other management strategies with a healthcare provider might be appropriate.

Causes Migraines are thought to occur when blood flow in the brain is altered and certain nerves in the brain send abnormal pain signals throughout the head. These signals trigger the release of various brain chemicals ( neurotransmitters ) in the brain, which leads to inflammation, particularly of blood vessels and the membrane that covers the brain and spinal cord (meninges). This inflammation causes many of the signs and symptoms of a migraine, including the throbbing pain, nausea, and sensory sensitivities. However, it is unclear what leads to the abnormal nerve signaling. Auras are thought to be caused by abnormal nerve signaling and associated changes in blood flow that spread across the brain. Additionally, the release of large amounts of the neurotransmitter glutamate is thought to contribute to aura. The causes of these imbalances are unclear. Migraines result from a combination of genetic, environmental, and lifestyle factors, some of which have not been identified. Variations in many genes have been found to be associated with the development of migraines with or without aura. These genes likely have varying degrees of impact among affected individuals. Most of the associated genes are active in the muscles that surround blood vessels ( vascular smooth muscle ) within the brain. These genes help regulate blood flow by controlling the narrowing and expansion of blood vessels. Many variants likely disrupt blood flow in the brain, which can contribute to developing migraines. Changes in blood flow in the brain or in the balance between vascular injury and repair (vascular homeostasis) also likely underlie the increased risk of stroke in people with migraines. Variants in genes that regulate levels of glutamate or the activity (excitability) of certain nerve cells in the brain have also been found in people with migraines. Nongenetic factors also play a critical role in developing a migraine. Migraine headaches can be triggered by skipping meals, caffeine or alcohol overuse, certain foods, poor sleep, emotional stress, hormonal changes, or minor head trauma. Excessive use of pain relief medications can also trigger or worsen migraines.

The prevalence of migraine is 15 to 20% in women and 4 to 7% in men, and migraine headaches are estimated to afflict 1 billion people worldwide.In children the prevalence may be as high as 17% and is equal in boys and girls. At puberty, the prevalence rises in girls and remains higher throughout their lifespan. The highest prevalence occurs between the ages of 25 and 55 years, but migraines also affect older adults.Migraine with aura affects 5% of the adult population, and 90% of auras are visual. Migraine is more prevalent in White persons and in those with a lower socioeconomic status or income. Comorbid conditions and lifestyle factorsthat may be associated with migraine headache include epilepsy, stroke, depression, anxiety, asthma, myocardial infarction, patent foramen ovale, Raynaud phenomenon, irritable bowel syndrome, and pain disorders such as fibromyalgia. Menstruation and ovulation may increase the frequency of headache.
