An exaggerated or unusual hypersensitivity to foreign protein or other substance?

This condition is known as an allergy, where the immune system overreacts to a harmless substance (allergen) as if it were a threat. Common allergic reactions include sneezing, itching, hives, and in severe cases, anaphylaxis. Treatment may involve avoiding the allergen, medication, or allergy shots to desensitize the immune system.


Is the most common type of immediate hypersensitivity?

The most common type of immediate hypersensitivity is type I hypersensitivity, also known as allergic reactions. This type of hypersensitivity involves the production of IgE antibodies in response to an allergen, which leads to the release of histamine and other mediators that cause symptoms such as itching, hives, and anaphylaxis.


How is anaphylaxis treated?

The emergency condition of anaphylaxis is treated with injection of adrenaline, also known as epinephrine.


What microbe causes Peanut Allergy?

Allergies are not a disease. They are not caused by bacteria, what happens during an allergy is that your body over-reacts to a small amount of protein from something, also known as an allergen. This then makes the body ill, often putting the body through 'shock' also known as anaphylaxis.


Also known as hypersensitivity?

Allergen


What is the treatment for anaphylaxis?

anaphylaxis is treated with injection of adrenaline, also known as epinephrine. People who are prone to anaphylaxis because of food or insect allergies often carry an "Epi-pen" containing adrenaline in a hypodermic needle.


Can Penicillin Kill You if you already broke out of hives from it?

Yes, penicillin can potentially be life-threatening if you have a history of allergic reactions, such as hives. An allergic reaction can escalate to anaphylaxis, a severe and rapid response that can be fatal if not treated promptly. If you have previously experienced hives after taking penicillin, it is crucial to avoid the drug and consult a healthcare professional for alternatives. Always inform your doctor about any known allergies to medications.


How does an allergic reaction feel?

Allergic reactions can be mild, like sneezing or coughing. They can also be severe, such as anaphylaxis. Anaphylaxis is characterized by difficulty breathing or swallowing, swelling of the lips, tongue, or other parts of the body, dizziness or loss of consciousness. This usually occurs within minutes after contact with the allergen but can take up to 4 hours. These kind of allergic reactions are rare and can be treated successfully if treated correctly.If the allergen is breathed in, such as flower pollen the reaction usually occurs in the nose, and eyes. If the allergen is eaten, such as peanuts, then the reaction is usually in the mouth, tongue, throat and/or the intestinal tract. If the allergen touches the skin, such as poison ivy, the allergic reaction is usually swelling or itching.Histamines, along with other similar chemicals, are known as mediators and are generally responsible for many of those physiological reactions we associate with an allergic reaction such as itching and itchy eyes, rashes, hives, sneezing, nausea, and a runny nose. They can also induce much more serious reactions including difficulty breathing (constriction of the airway), a dilation of blood vessels, and of course, anaphylactic shock.


What is the most serious type of allergic reaction?

Death Anaphylaxis or Anaphylactic shock, is the most serious type of allergic reaction. It is the result of an antigen-antibody reaction that stimulates a massive secretion of histamine.


Does anyone have a malt allergy?

Yes, it's not the most common allergy but it is known as an allergen for some.


Can a person can go into anaphylactic shock on their first exposure to an antigen?

Yes, it is possible for a person to go into anaphylactic shock on their first exposure to an antigen if they have a severe and immediate allergic reaction. This is known as anaphylaxis and can be life-threatening.
