Allergy is a common name used by people whose body becomes hypersensitive to certain substances. The reaction can occur from pollen, foods, medication, or bee venom. It is vital to note that these substances are not harmful to other people. There are three types of allergy testing which are blood tests, skin prick tests, and patch tests. These tests are done to establish and analyze any immune reaction in your body. Allergic reaction is usually caused by an allergen. When an allergen enters the body, the immune system tries to destroy it as though it was a harmful substance. Below we are discussing the risk, symptoms, and treatment associated with allergies.
What is an Allergy?
An allergy is when the body’s immune system reacts to a harmless substance in the body. The allergic reaction occurs over time of exposure to the allergen. However, there is less reaction the first time of exposure. With time, the immune system can build up sensitivity and learn how to recognize the allergen. Some allergies are seasonal such as those caused by pollen, while others occur often. The body starts forming antibodies to fight when these exposures occur.
The Allergy Symptoms
There are different kinds of reactions and irritation depending on the kind of allergy you are experiencing. Most reactions may occur on the skin while others on the nasal passage and other body parts.
In case you have a food allergy, the reaction will be vomiting, swelling of the lips, tongue, face, and throat. Some may also experience diarrhea, stomach cramps, and shortness of breath.When your allergy is a result of medication, you will have symptoms like swelling of the tongue, a rash, itchiness, or wheezing.
Some people may experience anaphylaxis symptoms, which is the severest form of allergic reaction. The symptoms of anaphylaxis appear quickly within minutes and can be life-threatening as a medical emergency. Some of the symptoms include difficulty breathing, swelling, flushing, and itchiness. People may also feel dizziness and fainting, low blood pressure, loss of consciousness, and changes in heart rate.

Treatment and Prevention
The best way to prevent allergy is to avoid getting into contact with the allergens, which often fails most people with or without knowing. The drugs given do not heal but rather help manage the reaction. There is a medication that can be provided, such as immunotherapy, decongestants, and antihistamines. This option will help control the reaction, even when you get into contact with the allergens.
In case of anaphylaxis, the person requires immediate treatment as most have difficulty breathing. They can also consider using epinephrine auto-injectors.
