Which of the following is a Common Cause of Hypersensitivity Diseases?

People have different levels of sensitivity to a given product or substance. Some people may be very sensitive to a product. And develop hypersensitivity diseases as a result of exposure. At the same time, some other people may not experience any symptoms from the same product. In addition, some people experience hypersensitivity disease symptoms. Following exposure but may not be allergic to the product as such.

The components of hypersensitivity disease include inflammation, immune response, and some genetic causes. Hypersensitivity diseases are common, especially in pharmaceutical drugs. And it affects thousands of people each year. Read this article to find out more about the common causes of hypersensitivity diseases.

Common Cause of Hypersensitivity Diseases

Hypersensitivity diseases are caused by an abnormal response of the immune system to normally harmless foreign substances. The immune system normally protects us from infections. And other harmful agents by attacking them with antibodies and other white blood cells. Hypersensitivity diseases occur when this response is excessive, resulting in inflammation and tissue damage.

Types of hypersensitivity diseases include:

• Allergies:

An allergy is caused by a reaction to an allergen (a substance that causes allergic symptoms). Common allergens include pollen, dust mites, animal dander, insect stings, mold spores, and food allergens. Allergies can cause sneezing, runny nose, and itchy eyes; they can also lead to asthma attacks in some people.

• Autoimmune disease:

An autoimmune disease occurs when the body mistakenly attacks healthy tissue in its own body instead of fighting infections or other harmful agents. Examples include Type 1 diabetes mellitus, rheumatoid arthritis, multiple sclerosis, and systemic lupus erythematosus (SLE).

• Asthma:

It is also caused by an overactive immune system, but instead of releasing histamines it inflames the lungs’ airways causing them to constrict and making it difficult for people with this condition to breathe normally. Anaphylaxis occurs when someone is allergic to something they eat or drink that causes their immune system to release high levels of histamine into their bloodstream at once, which can lead to shock and even death if treatment isn’t received immediately.


When these particles come into contact with the mucous membranes of your nose and throat. They can trigger an allergic response. The allergic response causes inflammation in your airways, leading to a variety of symptoms including sneezing, runny nose, wheezing, and coughing.

Some people are more likely to develop hypersensitivity diseases because they have a genetic predisposition to allergies or asthma. This means that their bodies are less able to fight off allergens than others with similar exposure levels.
