i have had 2 migraines in the last month where before i have only had approx4 in my entire life! what causes these and how can i stop them
I have always heard that many different things can cause migranes such as straining to watch tv, read, or a computer screen, even video games for too long. I've also heard it could be caused by needing to have your vision checked, too much or too little caffiene. Allergies & sinus problems, or something that a nerologist might want to cat scan just to be safe. Hope this helps a little.
The causes of migraine headaches are not clearly understood. It was proposed that a migraine begins with a spasm, or partial closing, of the arteries leading to the main part of the brain (called the cerebrum). The first spasm decreases blood supply to part of the brain, which causes the aura (lights, haze, zig-zag lines, or other symptoms) that some people experience. These same arteries then become too relaxed, which increases blood flow and causes pain.
The chemicals dopamine and serotonin were found to play a role in migraine headaches. (These chemicals are called neurotransmitters.) Dopamine and serotonin are normally found in the brain, but they can cause blood vessels to act in uncharacteristic ways if they are present in abnormal amounts or if the blood vessels are unusually sensitive to them.
Together, these 2 theories have come to be known as the neurovascular theory of migraine, and it is presently believed that both theories provide insight into the causes of headache.
Various triggers are thought to initiate migraine headaches in people who are prone to developing them. Different people may have different triggers.
Smoking has been identified as a trigger for many people.
Certain foods, especially chocolate, cheese, nuts, alcohol, and monosodium glutamate (MSG), may trigger migraine headaches. (MSG is a flavor enhancer used in many foods, including Chinese dishes.)
Missing a meal or changing sleep patterns may bring on a headache.
Stress and tension are also risk factors. People often have migraines during times of increased emotional or physical stress.
Contraceptives (birth control pills) are a common trigger. Women may have migraines at the end of the pill cycle as the estrogen component of the pill is stopped. This is called an estrogen-withdrawal headache.
Avoid factors that cause a migraine attack (for example, lack of sleep, fatigue, stress, certain foods, vasodilators).
Treat accompanying conditions (for example, anxiety, depression).
Oral birth control agents (contraceptives) may increase the frequency of headaches in females. Women may be advised to discontinue oral contraceptives (or to use a different form) for a trial period to see if they are a factor.
For more details, please seek medical advice, take care, best wishes!
There are a zillion different things that can trigger migraines. People often find relief when they discover their trigger item. Sometimes it's chocolate, alcohol or caffeine... in my case it's neurological and is from a neck injury.
The first step (in my humble opinion) is to see your primary doctor since this is "new" for you and discover if there is any physical reasons why this has begun to be frequent for you.
