Migraines occur when blood vessels of the head and neck spasm or constrict, which decreases blood flow to the brain. Minutes to hours later, the blood vessels dilate (enlarge), resulting in a severe headache. Common migraine may be accompanied by symptoms other than headache but only rarely includes any preliminary symptoms (aura). Multiple mechanisms trigger the spasm and subsequent blood vessel dilation.
Attacks of migraine headache may be associated with allergic reactions, bright lights, loud noises, relaxation after a period of physical or mental stress, prolonged muscle tension (or tension headache), lack of sleep, smoking or exposure to tobacco smoke, missed meals, specific foods, alcohol use, caffeine, menstrual periods, use of oral contraceptives (birth control pills), and other conditions.
Foods associated with migraine include foods containing the amino acid tyramine (red wine, aged cheese, smoked fish, chicken livers, figs, some beans), chocolates, nuts, peanut butter, fruits (avocado, banana, citrus fruit), onions, dairy products, baked goods, meats containing nitrates (bacon, hot dogs, salami, cured meats), foods containing monosodium glutamate (an additive in many foods), and any processed, fermented, pickled, or marinated foods.The occurrence of common migraine may be reduced in high-risk people who avoid factors that have been associated with previous migraine. Preventive (prophylactic) medications may be advised for some people.
In homoeopathy medicine like Bell, Sanguneria, Gelsimium, Cimicifuga are used for the treatment. The proper analysis of the case with the qualified homoeopathic physician will give the better results.
