Things That Often Cause Headaches After Eating
1. Allergies and Food Sensitivities
Some foods can cause headaches, especially if you have an allergy or if your body does not react well to them. Some of the most common things that cause this are:
Dairy Products: If you cannot break down lactose, eating dairy like milk, cheese, or yogurt can give you stomach pain and headaches.
MSG (Monosodium Glutamate): MSG is very common in the foods you get in stores, soy sauce, and when you eat out. It can give some people headaches.
Foods High in Tyramine: Tyramine is a substance found in some foods, such as cheese, cured meats, and wine. It can give some people a migraine.
Caffeine: Some people say that caffeine makes their headaches feel better for a short time. But if you have too much caffeine, it can make the headaches worse. If you stop having caffeine all at once, the headaches can also get worse.
Chocolate: Some people get headaches when they eat chocolate. This may be because the chocolate has caffeine and sugar in it.
Keeping a food diary can help you figure out what foods are making you sick if you think you might have a food intolerance or allergy.
2. Eating Too Much or Too Fast
Headaches can happen when you eat a lot of food. Your body has to work hard to digest a big meal when you eat too much, which can change the flow of blood and cause a headache. Your digestive system can also get too full if you eat too quickly, which can make you feel bad all over, even in your head.
Overeating: When you eat a lot of food, your digestive system may get a lot more blood flow all at once, which could make your head hurt.
Eating Too Quickly: When you eat too fast, you might take in air. This can make you feel full and not comfortable. It can also give you a headache.
3. Low Blood Sugar
Not eating for a long time can make your blood sugar go down. This can give you a headache. People who have diabetes or skip meals may get this more. If your body does not have enough fuel, you might get a headache. This is your body’s way of telling you it needs more energy.
Not eating enough: If you do not eat enough, your blood sugar can go down. This can cause you to get a headache.
Eating Foods High in Sugar: When you eat a lot of sugar, your blood sugar levels can go up fast and then drop. This can make you get a headache.
4. Lack of water
Dehydration can sometimes make your head hurt after you eat. Your body may be more likely to get headaches, especially after meals, if you haven’t been drinking enough water during the day. When you don’t drink enough water, the blood vessels in your head can narrow, which can cause a headache.
5. Foods That Can Cause Migraines
Some foods can trigger migraines in people who get them. Some common things that can cause migraines are:
Processed Foods: Some of these have preservatives like nitrates or nitrites that can cause migraines in some people.
Alcohol: Red wine is a well-known trigger for migraines.
Caffeine: For some people, caffeine can cause a headache either when it starts or when its effects wear off.
If you get migraines often, figuring out what causes them and staying away from those things can help you have fewer headaches.
6. Changes in Blood Pressure
When you eat, your blood pressure can change. This happens because your body sends more blood to help your stomach work. If you have high or low blood pressure, you may get a headache when these changes happen. Eating foods with a lot of salt can also make your blood pressure go up. This can give you a headache, too.
7. How to Sit and Digest
How you sit when you eat can make it tough for your body to take in food. It may even cause you to feel a headache. If you slouch or put too much weight on your stomach while eating, you may feel some acid coming up. You could feel sick to your stomach, and this may lead to your head hurting. Also, if you lay down right after you eat, your food may not get broken down well in your body. This can give you a headache, too.
8. Changes in hormones
Hormone changes can lead to headaches after eating for some people. This happens a lot in women who feel pain during their period or when they are pregnant.Some foods, like chocolate, can make these headaches worse.
How to Stop Getting Headaches After Eating
The first step to getting rid of your headaches after you eat is to figure out what is causing them. If you don’t want to get headaches after you eat, you can try these things:

Eat Slowly: Take time when you eat. If you rush, you may take in air. Eating slow lets your stomach work better and helps you digest food.
Stay Hydrated: Make sure you drink enough water all day. This helps keep you from getting dehydrated. Dehydration is one reason people get headaches.
Find Out What Foods Trigger Headaches and Stay Away from Them: Keep a note of the foods you eat. Look for any food that is making you get headaches. When you find out which food is the reason for it, it will be good for you to stay away from that food so you feel better in the future.
Cut back on caffeine and alcohol: If you feel that these things make your headaches worse, try using less of them. You can also take them out of your diet to see if that helps you feel better.
