Understanding Allergies: An In-depth Look

Allergic reactions are common and affect millions of people around the world. Allergies are an immune reaction to harmless substances, like dust, pollen or some foods. The symptoms can be mild, such as sneezing or itching. They may also become severe like anaphylaxis. Understanding the causes, treatment, and prevention of allergy is important for managing this health problem.

What are allergies?

Hypersensitivity to substances entering or coming into contact with your body can cause allergies. Allergens are substances that, while being harmless for most, can cause allergic reactions when they come into contact with the body. According to the World Health Organization, allergies and asthma, in particular, allergic rhinitis and allergic asthma, are estimated to affect 500 and 400 millions people worldwide, respectively.

Allergic reactions vary in severity depending on who is affected and what allergens are involved. While some people may experience minor symptoms like a skin rash, others can suffer severe reactions such as difficulty breathing, low blood pressure and even loss of consciousness.

Allergies: Common Causes

Allergies can be caused by a variety of factors. These include genetics, environmental exposure and even the environment itself. These are common allergens.

• Pollen is produced by trees, grasses, and weeds.
• Dust mites, cockroaches droppings
• The dander and saliva of animals
• Mold Spores
• Especially peanuts, trees nuts, milk and eggs, as well as wheat, soya, shellfish, and fish
• Some medicines, like penicillin
• Stings of bees and wasps as well as mosquitoes
• Other substances such as latex that may come in contact with skin

Allergic reactions and their treatment

Allergy treatment aims to reduce symptoms and avoid allergic reactions. Some common treatment options include:

• Use antihistamines for sneezing and runny eyes.
• Use of nasal corticosteroids for the treatment and prevention of nasal inflammation
• Decongestants to remove mucus from nasal passageways
• Immunotherapy (allergy shots) can reduce sensitivity to allergens
• Injections of epinephrine for severe allergic reactions

The American Academy of Allergy Asthma & Immunology reports that allergy shots reduce allergy symptoms by about 85% .

Experts' Opinions about Allergies

Allergies are considered a major public health issue by experts. Maria Garcia-Lloret is a pediatric allergy specialist at UCLA Mattel Children's Hospital. She says that "early diagnosis and early treatment are crucial in order to avoid complications." According to a study in The Lancet, early exposure, especially peanuts, reduces the likelihood of allergies later in life.

Prevention and Natural Remedies

In addition to medical treatment, one can also take preventive and natural measures against allergies. They include:

• Cleaning the environment regularly to reduce exposure to mold and dust mites
• Hypoallergenic Products
• Avoiding outdoor activities during high pollen times
• Use a dehumidifier as a preventative measure against mold growth
• A balanced diet high in omega-3 fats and antioxidants is recommended

Allergies are an issue of health that is prevalent and affects many people. By reducing the impact of allergies on your daily life, you can reduce their frequency by identifying common causes and treatments.
