An allergy is an exaggerated immune response or reaction to substances that are generally not harmful.Allergies are relatively common. Both genetics and environmental factors play a role.The immune system normally protects the body against harmful substances, such as bacteria and viruses. It also reacts to foreign substances called allergens, which are generally harmless and in most people do not cause a problem.
But in a person with allergies, the immune response is oversensitive. When it recognizes an allergen, it releases chemicals such as histamines. which fight off the allergen. This causes itching, swelling, mucus production, muscle spasms, hives, rashes, and other symptoms, which vary from person to person.Common allergens include pollen, mold, pet dander, and dust. Food and drug allergies are common. Allergic reactions can also be caused by insect bites, jewelry, cosmetics, spices, and other substances.
Some people have allergy-like reactions to hot or cold temperatures, sunlight, or other environmental triggers. Sometimes, friction (rubbing or roughly stroking the skin) will cause symptoms.A specific allergy is not usually passed down through families (inherited). However, if both your parents have allergies, you are likely to have allergies. The chance is greater if your mother has allergies.Allergies may make certain medical conditions such as sinus problems, eczema, and asthma worse.
Symptoms:-Allergy symptoms vary, but may include:
Breathing problems (coughing, shortness of breath)
Burning, tearing, or itchy eyes
Conjunctivitis (red, swollen eyes)
Coughing
Diarrhea
Headache
Hives
Itching of the nose, mouth, throat, skin, or any other area
Runny nose
Skin rashes
Stomach cramps
Vomiting
Wheezing
What part of the body is contacted by the allergen plays a role in the symptoms of allergy you develop. For example:
Allergens that are breathed in often cause a stuffy nose, itchy nose and throat, mucus production, cough, or wheezing
Allergens that touch the eyes may cause itchy, watery, red, swollen eyes.
Eating something you are allergic to can cause nausea, vomiting, abdominal pain, cramping, diarrhea, or a severe, life-threatening reaction
Allergens that touch the skin can cause a skin rash, hives, itching, blisters, or even skin peeling
Drug allergies usually involve the whole body and can lead to a variety of symptoms
Treatment
Severe allergic reactions (anaphylaxis) require treatment with a medicine called epinephrine, which can be life saving when immediately given.The best way to reduce symptoms is to try and avoid what causes your allergies in the first place. This is especially important for food and drug allergies.
There are several types of medications available to prevent and treat allergies. Which medicine your doctor recommends depends on the type and severity of your symptoms, your age, and overall health.
Specific illnesses that are caused by allergies (such as asthma, hay fever, and eczema) may require other treatments.

With Spring in full swing, I have been having the most violent sneezing fits of my life. I'm so sick of my allergies and can't wait for them to go away. I really need to take some medicine to prevent it. Hopefully, there are some procedures I can undergo in order to take care of them. http://www.stclairemedical.com/allergies/
