Numerous sources can cause people to suffer with an allergic reaction. Some of the common sources of allergies include: pollen, mold, dust mites, and food. If you suspect that you may have an allergy, your doctor may be able to find out exactly what you are allergic to and the best treatment for you.

If you think you are suffering from an allergy related problem, consult your physician to be sure. He will be able to tell you what your allergy is and the best option for your treatment.

The genetic link is whether you develop an allergy or not, due to your parent's history. Having a reaction to a certain substance may indeed just be because your immune system is weak. People may have a weak immune system due to infection or pregnancy.

Another reason for having an allergic reaction may be due to your weakened immune system. If you have had the flu or you are pregnant, you may develop sensitivity to a substance you wouldn't otherwise be affected by.

Allergies are the result of our body's way of dealing with different substances. Your immune system may react as though pollen or mold is harmful to you. When sneezing, watery eyes, hives, or runny noses appear, you are having a reaction to this substance.

During a severe reaction, called anaphylaxis, your itching may turn to swelling, pain, and vomiting. If this happens seek immediate attention.

If all these methods fail, you may have to take shots or seek your doctor's advice on a method that may be just right for you.
