Allergies and Allergy symptoms


What is an allergy/Allergies and what are the symptoms ?. An allergy is a high reaction that occurs by the immune system in response to exposure to certain foreign substances inside the body.

A person’s immune system fights off invading organisms and it builds up antibodies to prevent foreign substances to harm the person’s body from Allergies and show some & Allergy symptoms

These antibodies can become activated in response to new invasions.

If a person’s immunity system becomes activated, the reaction caused by the presence of the invader or foreign particle can trigger reactions.

if a person feels an allergic reaction, people often feel that they are going to vomit

Eg: IF a person is suffering from pollen allergy

Someone with a pollen allergy has an immune system response that causes their body to react and release chemicals in their nose. This causes small sacs at the back of the nose to swell up and itch.

Pollen allergy symptoms can take place throughout the year, but these tend to increase during the spring and summer months.

What to do?

In a pollen allergy, a person’s symptoms tend to occur and worsen after exposure to pollen.

  • Cough & sneezing,
  • Itching.

Some key facts about Allergies and allergy symptoms

  • Food Allergy affects about 20 million Americans in the U.S. Food allergy is when the body’s immune system attacks proteins on the surface of the foods we eat.
  • An allergic reaction that involves all the body’s systems occurs when the immune system mistakes the protein in foods as a foreign invader, causing it to release chemicals called histamine, epinephrine, and other substances that cause inflammation in the body’s tissues.
  • Symptoms vary in severity, but an allergic reaction generally worsens as an allergy progresses, and can include hives, rashes, itching, and difficulty breathing. Source: Mayo Clinic

A doctor will recommend an allergy test to the protein or other substances in food for a foreign invader.

If a person does not have a known allergy, allergy testing is used to test for an existing sensitivity.

A skin prick test is one option. A doctor will place a few drops of liquid food allergen on a skin patch to cause a small rash, known as a pruritic reaction, on the area.

The skin will become red and itchy, but it’s possible not to notice the skin rash.


Different types of Allergy on the Skin ( Allergies and allergy symptoms)

  • Rashes. Areas of skin that are irritated, red, or swollen, and can become painful or itchy to the person.

Allergy Reaction( Allergies & Allergy Symptoms)

drug allergy is an allergic reaction to a certain type of medication given to the person which does not show patient compliance with the medication.

With an allergic reaction, your immune system, which fights infection and disease, reacts to the drug.

This reaction can cause symptoms of rash, fever, and trouble breathing. True drug allergy is not common.

The condition occurs during drug allergy

  • Inflammation in the kidneys. inflammation in the kidney can also lead to Acute nephritis has several causes, and it can ultimately lead to kidney failure if it’s left untreated for a sometimes
  • Drug-induced anemia leads to a decrease in red blood cells And some common symptoms are irregular heartbeats, shortness of breath, and fatigue

Drug-induced immune hemolytic anemia is a blood disorder that occurs when a medicine triggers the body’s defense (immune) system to attack its own red blood cells.

This causes red blood cells to break down earlier than normal, a process called hemolysis.

  • Serum sickness is a similar kind of response that is related to allergy also. it occurs when a substance triggers immune symptoms

It is also known as type III hypersensitivity reaction.

if an injection of heterologous or foreign, medication protein or serum is injected into the person

It is also known as an immune-complex-mediated hypersensitivity reaction.

Food Allergy

Food allergy is known as an abnormal response, to a certain kind of food as our system takes a harmful substance. In response to that our body show some kind of allergy known as food allergy

Food allergy can occur due to Even a tiny amount of the allergy-causing food given to a person

what is a food allergy?

food allergies are a part of a person’s food preferences from some foods that people have allergies to

food allergies are the byproduct of a body’s immune system reacting to the food that it comes into contact with. a food allergy is a bodily response, rather than an injury.

some people are allergic to different types of food types; some are allergic to certain foods.

food allergies can cause a person to:

  • can have allergic symptoms when eating certain foods
  • have an allergic reaction to food that they are allergic to
  • have a history of serious allergic reactions
  • a food allergy is often TO SOME SENSITIVE PEOPLE, but not always, due to an allergy to a certain type of protein.

In some cases, a person may be allergic to something other than a protein.

A food allergy is not the same thing as an anaphylactic food allergy. Anaphylaxis is a severe and potentially life-threatening allergic reaction.

A food allergy can be caused by several different proteins, and only some are allergenic.

Allergy treatment

The most effective way to prevent allergy is to stay as far and protective from allergen as much as possible and prevent any type of contact

Allergy Medicines

The most common drug given to allergy patients is Antihistamines.

But the doctor can prescribe other medicines on the basis of the severity of the disease

  • Cetirizine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose. It is using to treat cold or allergy symptoms such as sneezing, itching, watery eyes, or runny nose.
  • Levocetirizine is an antihistamine used to relieve allergy symptoms most effective as over-the-counter drugs. it also used in itching and hives

How the allergy is treated and diagnosed

There are many types of ways allergy is being treated it can differ according to the patient severity and according to the patient compliance

Lastly, a blood test and skin test will perform that if u have been in contact of any type of suspected particle

Allergy Blood Test

Immunoglobulin E (IgE) is a class of antibody (immune protein) associated with allergic reactions. It is normally found in very small amounts in the blood. This test measures the amount of allergen-specific IgE in the blood in order to detect an allergy to a particular substance.

I this test IgE is an antibody that functions as part of the body’s immune system, its defense against “intruders.” and other foreign particles which enter into the body.

When a person is a predisposition to allergies is exposed to several kinds of potential allergens such as food, grass, or animal dander for the first time, that person becomes sensitized by the allergen.

The person’s body perceives the potential allergen as a foreign substance and produces a specific IgE (Immunoglobulin E) antibody.

It binds to specialized mast cells in the skin, respiratory system, and gastrointestinal tract, as well as to basophils (a type of white blood cell found in the body (helps to protect from microbes and several other microorganisms ) in the bloodstream.

And when te person comes with the next exposure of allergen these attached IgE antibodies recognize the allergen

It causes the mast and basophil cells to release histamine and other chemicals, resulting in an allergic reaction that begins at the exposure site.

Skin Allergy test.

skin allergy test is known as the most common type of allergy done by the Doctor. During skin prick or scratch testing, the suspected allergen is kept on the skin and the test results are read after every 15 minutes.

IF the suspected allergen is not found on the first attempt, more than 50 suspected allergen is tested one by one to find the suspected allergen.

There are a certain type of skin allergy which are

  • Bromelain. so these days is a popular natural remedy because, in addition, it shows good results in treating and swelling or inflammation, especially if the person is suffering from sinuses.

Research on mice suggests that bromelain can reduce allergic sensitization and allergic airway disease. As it has anti-inflammatory and anti-allergic properties.

  • Butterbur. used in the treatment of hayfever, and use in limited allergy


Allergy! allergy is not a very dangerous disease meanwhile, but if the person does not take care properly in addition to health it can lead to server effects. on the person,
