10 Signs You Could Have Allergies

6. Vomiting

More often than not, vomiting will occur due to a food allergy. In most cases, vomiting will be effortless, based on your body's natural reflux. When suffering from a food allergy, for instance, your immune response will be oversensitive.

Some of the most common allergens include eggs, fish, milk, nuts, soy, shellfish, and wheat. You may also experience stomach cramps and diarrhea. If you notice that a certain food bothers you, to the point that symptoms surface, avoid that food until you've been properly tested.
