An allergy is a reaction that some people have to certain things like foods, pollen, or animals. It can cause symptoms like sneezing, itching, and coughing. If you have an allergy, your body is not able to tolerate whatever you are allergic to, and it causes your body to overreact. It is important to know what you are allergic to so you can avoid it and stay healthy. If you think you have an allergy, you should talk to a doctor so they can help you figure out what is causing your symptoms.
