Do you experience a headache when you skip a meal? Skipping meals is never a good idea.

Not only can it cause fatigue, decreased focus, and a low energy level, some people experience headaches when they miss a meal.

What causes a headache from not eating – and how can you prevent them?


Low Blood Sugar

Skipping meals can cause blood sugar drops, which trigger headaches in some individuals. When blood sugar levels drop too low, the body responds by pumping out hormones that raise sugar levels higher – so cells can get more energy. These include epinephrine and norepinephrine, two hormones that constrict blood vessels in the brain – and also trigger a headache. How does a low blood sugar headache feel? They’re usually dull and most prominent around the temples, although the characteristics can vary from person to person.

Not surprisingly, skipping meals can trigger migraine headaches in people predisposed to them.  Eating meals irregularly and loading up on foods that are high in simple carbohydrates cause fluctuations in blood sugar levels that can bring on headaches in migraine sufferers. With migraine headaches, it’s not only important what you eat, but how often you eat it.


What you eat, and what you drink, or don’t drink, can contribute to low blood sugar headaches. Dehydration commonly triggers headaches in children – and can do it in adults too.  Why is dehydration a cause of headaches? No one knows for sure. One theory is that lowered pressure due to lack of water stimulates pain receptors that line the covering around the brain called the meninges. This triggers a low blood sugar headache.

Ever wonder why so many people have a headache after a night of drinking alcohol? It’s dehydration triggering those pain receptors on the meninges again. Remember, alcohol is a diuretic, which increases fluid loss. It’s tempting to reach for a cup of coffee to offset that hangover headache, but coffee is a diuretic, which contributes to fluid loss. It’s better to stick with water – and lots of it.


Eat small, frequent meals throughout the day and include a small amount of protein and complex carbohydrates. Stay away from simple carbohydrates such as desserts, white potatoes, white rice, and white bread that are rapidly absorbed and trigger rapid drops in blood sugar levels. Always eat breakfast before leaving the house in the morning and limit caffeine. Caffeine withdrawal can be a cause of headaches too. Eat wisely and frequently to prevent a headache from not eating.

  1. Aw, this was an exceptionally good post. Finding the time and actual effort to generate a superb article… but what can
    I say… I procrastinate a lot and don’t manage to get nearly anything done.

    1. Hey, I have had migrains forveer. I always get them with my seizures. It is okay to take extra Excedren however if you take it too often you can develope ulcers as it contains whatever that drug is. It can also cause ulcers to bleed, so be carefull. Avoid bright lights and the television when you are getting a migrian. It is also time to talk to your doctor. You need to be safe and make sure there is no underlying cause. Also, the doc can perscribe imitrex or some such medicine to take when you get a headach, or a preventative medicine like topomax, although it has some rough side effects. In the meantime my advise is what my neuro tells me avoide the c’s .. caffine, chardinae (all alchohol for that matter, it constricts the blood vessels), cheese, and chinesee food. For whatever reason each of these things can cause or worsen migrains. I know how much they suck, so good luck.

    1. I suffered from migarines for years until i was refered to a headache specialist , not a neurologist , but a headache specialist, after my initial consultation, she felt that my migarines were caused by a vitamin deficiency, she ordered tests, and sure enough, B12 deficient. Ever since then, i take 1000 mcg of B12 every day and have not even had so much as a hint of a headache since then.Miraculous drugs for migrines that are available only with a prescription. Migrine drugs arrests the vascular problems that cause the pain within a short period. Contact your doctor to get a prescription for Imitrex or other medicines. Some people can completely control migraine problems with the newer drugs.Sometimes a cold cloth over your head and a dark room will help.

  2. I’m impressed, I must say. Rarely do I come across a blog that’s both educative
    and interesting, and let me tell you, you have hit the nail
    on the head. The problem is something that too
    few people are speaking intelligently about.

    I’m very happy that I came across this in my search for something regarding this.

    1. Migraine is often anger-related. It may be all kinds of anger.What you can try is have her lie down on a bed and hold her outer ankles (between ankle and heel).You can do this 10 mientus with arms crossed and 10 mientus with arms normal.Ask her what feels best.Make yourself comfortable when you do it, be sure you take care of your back, eventually sit on a pillow.Eventually you can find a Jin Shin Jyutsu practitioner in your neighbourhood and try what effect this has on your mom. The practitioner will give selfhelp that is very suited to her project.You can also hold the inner ankle (between ankle and heel), and with the other hand hold toe per toe of that foot for 3 mientus per toe.Do both feet, That makes 30 mientus.See what the effect is. Ask her. Stick to one application and do it several days, you can do it up to 2 times a day.Only in this way, you will know what is the effect for her, now.Then you try the other application for some days, and see what is the effect on her.Another application she can simply do on herself is : Not particular for migraine, but it will help your applications to work properly through the body.Hope this may serve you well.Good luck.

  3. I love reading through an article that will make men and women
    think. Also, many thanks for permitting me to comment!

    1. I have suffered from Migraines for years now, so I have ptelny experience on this matter. (Too much if you ask me.) Taking three tablets of your Excedrine won’t hurt. I’ve for years taken OTCs (over the counter) Medication to alieviate my Migraines, but unfortuanatly, they don’t work on me. I would suggest that you go to your doctor, who might want to run some tests, MRI or Cat Scan to eliminate any other problem that might be causing your Migraines to occur. He can also perscribe you medication that can totally alieviate you pain. That is if Triptans will work for you. Right now I take Imitrex, it’s a Migraine medication, and I can tell you from experience that for me, this is the only medication I have found that worked. Usually within 30 to an hour my migraine is gone. It is wonderful. The only slight problem with these drugs is their cost which I am sorry to say is expensive. I talked to my doctor about this, and luckly for me, he is nice enough to give me free samples of this medication every few months. Otherwise I couldn’t afford it. I hope I helped you. Here is a good site to go to, it is a forum for people like you and me that suffer from constant headache/migraine pain.=GOOD LUCK TO YOU.

    2. When I feel that a migraine is about to start, I take some ecxidren and drink caffeine. If I am at home, I also apply heat to my neck and shoulders (where my migraines originate) or take a warm bath. All of the above help to open up the blood vessels in your head. Usually when you get the feeling that a migraine is going to start, you are feeling your blood vessels starting to constrict. Full-blown migraine pain occurs when your vessels over-react and open up really wide. So, if you can catch the migraine early enough (when it’s still in the blood vessel constriction phase), the caffeine and heat can usually help.

  4. It’s actually a great and useful piece of information. I am glad that you shared this useful information with us. Please keep us informed like this. Thank you for sharing.
