Allergies

Allergies are the symptoms that occur due to the sensitivity of a person to certain objects or substances, named allergens. The symptoms occur because the immune system reacts to the particular substance. Allergies occur with people all over the world to all kinds of substances, many different ones exist.

The most common are seasonal, hay fever like, allergies that are the result of certain trees, plants or pollens that get in the air at particular times in the year. Food and animal allergies occur very often as well. Some people also have a severe allergy to insects, especially those that have stingers.

The symptoms experienced vary by person. They can be classified by degree of severity, ranging from mild over moderate to severe allergic reactions. Even though there is no cure for allergies, they can be treated pretty well.

The majority of people only experience mild symptoms, like watery eyes, itching skin, a runny nose, coughing or hives. This type of allergy can be controlled well by using an antihistamine. Many are available over the counter, while others are only available on prescription. The effects can be reduced by not going outdoors too often during the time of the year when the pollens are airborne. Although an allergy shot might be a more convenient solution.

For others, the allergic reaction can be classified as moderate. In this case, the reaction will spread to other body parts. Breathing can become harder. A severe allergic reaction is the worst possible and can be life threatening. This can occur when exposed to various molds. Antihistamines and immunotherapy can help remedy the effects.

While they are very rare, they are to be considered a serious matter. Generally, these severe allergy reactions are caused by food allergies. Peanuts, eggs and milk are the most common. This can result into swelling of the face, abdominal pain, hives and severe cramps. It's very important to immediately consult a doctor when experiencing severe allergic reactions.

Pet allergies are very difficult to detect and control. It can take up to two years of exposure to an animal before an allergic reaction is developed and detected. In addition, it can take several months after ending the interaction with the animal at hand before the symptoms stop completely.

This combined makes it difficult to pinpoint the exact animal species to which the allergic reaction can be traced. Most people will also have a hard time being convinced that the allergy is indeed caused by that kind of animal, since the symptoms keep occurring even after the contact. They will easily think it must be something else causing it.
