Allergies are a common phenomenon that affects millions of people around the world. They are caused by the body’s immune system overreacting to harmless substances in the environment, such as pollen, mites, animal dander or certain foods. This overreaction can lead to a range of symptoms, from mild to severe, including itching, sneezing, runny nose, watery eyes, skin rash and difficulty breathing.

The primary role of the immune system is to defend the body against harmful invaders such as viruses, bacteria and other pathogens. It does this by producing antibodies that recognize and attack foreign substances.

However, in people with allergies, the immune system mistakenly identifies harmless substances as dangerous and triggers an immune response.

This response involves the release of histamine and other compounds that cause allergy symptoms.

The exact reasons why some people develop allergies and others do not are not fully understood. However, research suggests that genetics, environmental factors and lifestyle choices may play a role.

Genetics are believed to be a significant factor in the development of allergies.

Studies have shown that children are more likely to develop allergies if one or both parents have them. Certain genes are thought to be responsible for the overreaction of the immune system to harmless substances.

Environmental factors can also cause allergies.

Exposure to pollution, tobacco smoke and other irritants can irritate the airways and make them more susceptible to allergens. Certain foods and medications can also cause allergic reactions in some people.

Lifestyle choices, such as diet and exercise, can also affect the immune system’s response to allergens.

A healthy diet rich in fruits, vegetables and whole grains can help strengthen the immune system and reduce the risk of allergies.

Regular exercise can also help improve overall health and reduce the risk of developing allergies.

The physiological background of allergies involves the immune system’s response to allergens.

When an allergen enters the body, the immune system produces antibodies, which then bind to cells called mast cells. These mast cells release histamine and other chemicals, which cause allergy symptoms.

Histamine is responsible for many allergy symptoms, such as itching, sneezing and watery eyes. It also causes blood vessels to dilate, which can lead to inflammation and swelling. Other chemicals released by mast cells can also contribute to allergy symptoms.

There are several types of allergies, including seasonal allergies, food allergies, and drug allergies.

Seasonal allergies are caused by airborne allergens, such as pollen and mold spores.

Food allergies are caused by specific foods, such as peanuts, tree nuts and shellfish.

Drug allergies are caused by certain medications, such as antibiotics and pain relievers.
