You may have experienced or seen people getting headaches after eating a meal. This can happen due to numerous reasons like food allergy, low blood pressure, and more. Tap to know more reasons behind it!
Food Allergy
Sometimes, our immune system may overreact to the food and release some chemicals, causing food allergy and leading to headaches.
Low Blood Sugar
After eating a meal, our body may produce excessive insulin, dropping the blood sugar and leading to headaches, especially in people with diabetes.
Delayed Gastric Emptying
After eating food, the stomach may empty slowly, especially in people with gastrointestinal issues, leading to bloating, nausea, and headaches.
Dehydration
One of the most common causes of headaches is dehydration. Not drinking enough water, especially with spicy foods, can cause dehydration and lead to headaches.
Low Blood Pressure
Also known as postprandial hypotension, can also lead to headaches as blood is redirected to the stomach after eating, lowering blood pressure.
Caffeine Withdrawal Or Overconsumption
People who are used to caffeine may get a withdrawal headache if they skip it for even a day, whereas overconsumption of it can also trigger headaches.
Brain Freeze
When we eat something cold like ice creams, it may cause brain freeze, i.e., narrowing of the blood vessels in the brain, leading to sharp pain or headaches.
