10 Signs You Could Have Allergies

8. Skin Rash

A skin rash can be caused by a wide range of factors, including exposure to certain plants or even a reaction to a food. Two of the most common skin rashes are eczema and hives, which can easily be brought on by allergens. Once histamine is released, blood plasma begins to leak out of your skin's blood vessels.

If you experience any rash on your skin, it's important to have it examined. If you experience a chronic rash, this could be an indication of something more severe. For those who are prone to rashes, avoid itching problematic areas. This can expose open areas to bacteria, causing minor infections.

7. Swelling

If you react to an allergen by swelling, this can be dangerous. In some cases, your throat and lungs could be at risk, reducing your ability to breathe. In most cases, severe swelling occurs due to insect bites, food allergies, a reaction to medication, or pet dander.

If you notice that your fingers, tongue, and lips begin to swell, you may be having a reaction. If you notice that your throat is swelling, call an ambulance and take an antihistamine if possible. If this has happened before, it's important to discuss emergency options with your doctor - such as an EpiPen or an inhaler for future use.

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.
