Headaches

Headaches are quite common. They can be caused by a variety of factors, including stress, excessive alcohol consumption, dehydration, and exhaustion.

Food poisoning can result in gut inflammation as well as an increase in markers of inflammation throughout the body. Inflammation is linked to migraine headaches. Besides that, food poisoning can cause you to feel tired and dehydrated, which can contribute to a headache. It has been suggested that dehydration can have a direct impact on your brain, causing it to lose fluid and shrink temporarily. If you're vomiting or have diarrhea, both of which increase your risk of dehydration, you're more likely to get a headache.
