5. Headaches
Another symptom of food poisoning that many people tend not to recognize is a headache. These headaches can be quite mild or very severe. At times, the headache may become so severe that it causes a person to become nauseous or even begin to vomit. When a person has food poisoning, the headache may or may not be a symptom. Often times, other symptoms of food poisoning come up first and then a person develops a headache.
The reason for this is because many of the other symptoms of food poisoning can cause the body to become a bit dehydrated. After all, if you are vomiting and have severe diarrhea, chances are that you are not eating or drinking much of anything. When you are suffering from these ailments, make sure that you are trying to drink something all throughout. Even tiny sips can help you avoid dehydration. Dehydration is one of the main causes of these headaches.
