Allergies : Causes-Symptoms-Diagnosis-Treatment


 What are allergies?

An allergy occurs when your immune system reacts to a foreign substance or food that is not normally harmful.

Your immune system produces substances called antibodies when you have allergies. When you come into contact with an allergen, your immune system's reaction can cause your skin to become inflamed. The sinuses or the airways in the digestive system can be affected.

What are allergies?

Different people have different allergies and those allergies can range from mild irritation to anaphylaxis, which is a potentially life-threatening emergency. While most allergies cannot be cured, treatments can help relieve allergy symptoms.

  1. Integumentary system

Medical terms

  • Allergies are a type of immune reaction in which the body's system overreacts to a foreign substance, such as pollen, dust mites, pet dander, food, or drugs. Allergies can be seasonal, such as hay fever, or can last all year long. Symptoms of allergies vary from person to person, but they typically include sneezing, coughing, watery eyes, itching, and nasal congestion. Allergies can also cause serious reactions such as asthma, hives, and anaphylaxis.

  • Allergies are an overreaction of the body's immune system to foreign substances that are typically harmless to most people. Common causes of allergies include pollen, dust, pet dander, and certain foods. The body's immune system identifies these substances as a threat, and will produce antibodies to help fight them off. These antibodies will then trigger the release of histamines, which cause the associated symptoms of an allergic reaction such as itchy eyes, sneezing, and a runny nose.

  • Allergies are your body’s reaction to a usually harmless substance like spore, molds, animal dander, latex, sure foods and bug stings. allergic reaction symptoms vary from delicate – rash or hives, itchiness, runny nose, watery/red eyes – to severe. Treatments embody antihistamines, decongestants, nasal steroids, respiratory disorder medicines and therapy.

  • Allergies ar your body’s reaction to a substance it views as a harmful “invader.'' As an example, coming back into contact with what's usually a harmless substance, like spores, would possibly cause your system (your body’s defense system) to react. Substances that cause these reactions are referred to as allergens.

  • An “allergic reaction” is the method your body responds to the substance. a sequence of events occurs that end in AN sensitivity.

  • If you're at risk of allergies, the primary time you’re exposed to a selected substance (such as pollen), your body responds by manufacturing allergic (IgE) antibodies. The duty of those antibodies is to search out the allergens and facilitate taking them away from your system. As a result, a chemical referred to as aminoalkane is discharged and causes symptoms of allergies.

  • Allergies can be managed or eliminated with treatment from a doctor but identifying the cause of the allergy is important Some allergies can be cured while others will always require ongoing treatment To help you manage your symptoms follow the tips below: Step 1: Identify what's causing your allergic reaction Step 2: Take any prescribed medications and follow your doctor's recommendations for relief of symptoms Ask questions if something seems like it isn't working as well as before Nearly 70 percent of all people who have allergies also have asthma so remember that controlling both conditions at once may improve chronic problems associated with each condition individually.

Symptoms Allergies

Allergic symptoms can depend on the substance involved. Symptoms may vary depending on what the allergy is. Some severe cases of allergies can cause a life-threatening reaction called anaphylaxis.

Hay fever,Allergic rhinitis can cause: A person with allergic rhinitis may experience various symptoms, including a stuffy nose, wheezing, and coughing.

  • Sneezing

  • If you are experiencing an itch in your nose, eyes, or roof of the mouth, it might be a sign that you have a cold or the flu.

  • Runny, stuffy nose

  • If your child has watery red or swollen eyes (conjunctivitis), it means they have an infection in their eyes. You can treat the condition with antibiotics.

A food allergy can cause:

  • Tingling in the mouth

  • Swelling of the lips, tongue, or face.

  • Hives

  • Anaphylaxis

An insect sting allergy can cause:

  • There is a large area of swelling (edema) at the sting site.

  • Itching or hives all over the body

  • If you have a cough and it feels tight, produces wheezing or shortness of breath, you should see a doctor.

  • Anaphylaxis

A drug allergy can cause:

  • Hives

  • Itchy skin

  • Rash

  • Facial swelling

  • Wheezing

  • Anaphylaxis

Atopic dermatitis,A skin condition called "eczema" can cause skin to:

  • Itch

  • Redden

  • Flake or peel


An allergy can cause a severe reaction called anaphylaxis. This medical emergency can cause you to go into shock, and may include symptoms such as rapid heart rate, difficulty breathing, and a skin rash.

  • Loss of consciousness

  • A drop in blood pressure

  • Severe shortness of breath

  • Skin rash

  • Lightheadedness

  • A rapid, weak pulse

  • Nausea and vomiting

When to see a doctor

If you have symptoms after starting a new medication, or if the symptoms don't improve with over-the-counter allergy medications, you should see a doctor. If you have recently begun taking an allergy medication and you experience more serious symptoms, please call the doctor who prescribed it right away.

If you have a severe allergy, you would use anaphylaxis as a way to treat it. Anaphylaxis is an allergic reaction that can be life-threatening.If you are in danger, call 911 or your local emergency number. If you have an epinephrine auto-injector, such as an Auvi-Q EpiPen, give yourself a shot right away.

Even if your symptoms improve after receiving an epinephrine injection, you should still go to the emergency department in case your symptoms return.

If you've had a severe allergy attack in the past, make an appointment to see your doctor. Your doctor will need to do a lot of evaluation work in order to diagnose and manage your allergy properly.

Causes Allergies

An allergy begins when your immune system mistakenly believes a harmless substance is a harmful invader. The immune system then produces antibodies that remain in place for that particular allergen. When you are exposed to the allergen again, these antibodies can release a number of immune responses. histamine is a system chemical that causes allergy symptoms.

Common allergy triggers include:

  • Airborne allergens,Some things that could be on the list include pollen, animal dander, dust mites, and mold.

  • Anaphylaxis.If you have severe allergies, you are at a greater risk of experiencing this allergic reaction. Common triggers of anaphylaxis include foods, medications, and insect stings.

  • Asthma.People with allergies are more likely to have asthma, which is an immune system reaction that affects the airways. In some cases asthma is caused by exposure to an allergen in the environment (allergy-induced asthma).

  • Sinusitis and infections of the ears or lungs can occur.If you have hay fever or asthma, your risk of getting these conditions is higher.

Prevention Allergies

Preventing allergic reactions depends on the type of allergy you have. Some general tips to avoid allergic reactions include:

  • Avoid known triggers.If you're having allergy symptoms, try to avoid any possible triggers. For example, if you're allergic to pollen stay inside when pollen levels are high. If you're allergic to dust mites, dust and vacuum and wash bedding often.
