The causes of migraines are not fully understood, but they are believed to involve a combination of genetic, neurological, and environmental factors. Potential triggers include genetic predisposition, hormonal changes, certain foods, environmental factors, changes in sleep patterns, stress, and other medical conditions.
Migraines can also occur spontaneously without an identifiable trigger. Keeping a migraine diary to track potential triggers and working with a healthcare professional can help identify and manage individual triggers more effectively.
