Possible causes of headaches after eating
A person may suffer headache after eating carbs because it is triggered by various reasons. If you are dizzy after eating foods, perhaps you may suffer a sharp headache, dull pain or throbbing in the head. Here are some medical conditions that can be a reason that encourages pain or throbbing headache.
Allergic reactions are essentially immune system responses that occur when a person consumes a substance considered by the immune system as a threat. As a result, immunoglobulin E antibodies activate mast cells. These cells release histamine to support the body. Histamine release causes certain symptoms. Food allergy symptoms include itching, swelling of the face, itching, wheezing, runny nose, abdominal pain, cramps. Allergic reactions to food can also trigger migraine headache.
A migraine headache is characterized by a sense of throbbing in the head. Consumption of certain foods can trigger a migraine attack. Foods that may trigger migraines are chocolate, bananas, beef and chicken livers, bacon, soy sauce or citrus fruits. Consumption of foods containing additives can also be a contributing factor. Symptoms that may be experienced during migraine attacks include nausea, vomiting, photosensitivity. If your head feels sick every time you consume a certain type of food, it would be better to refrain from taking it.
3. High blood sugar
Pain in the head can also be caused due to fluctuations in blood sugar levels. When a person consumes certain foods, blood sugar levels rise rapidly. To make blood sugar levels normal then the body will produce insulin. When the brain does not receive sufficient amounts of glucose, the body increases the amount of blood flow to the brain, which causes an increase in blood pressure. The blood vessels in the brain may also contract and develop as a result of this fluctuation and it triggers the pain in the head.
Did you get headache after you eat salty foods? If yes, then it’s time you should check your blood pressure. Generally people who suffer from high blood pressure are advised to do a low-salt diet. If salt intake is very high, your kidneys may not be able to control the level of salt and may enter the bloodstream. If there is excess salt in the bloodstream, more water is drawn into the blood. This increases the volume of blood that in turn increases blood pressure.
If you have blood glucose and normal blood pressure, then the most likely cause is due to food allergies, not because diabetes. Try to check your health if you have headache after eating.
