Allergies

Allergies are a common condition where the immune system overreacts to substances that are typically harmless to most people. These substances, known as allergens, can include a wide range of things such as pollen, dust mites, animal dander, certain foods, and insect stings. When a person with allergies encounters an allergen, their immune system responds by releasing chemicals like histamines, which cause inflammation and a range of symptoms.

Symptoms of allergies can vary greatly depending on the type of allergen and the individual’s sensitivity. Common symptoms include sneezing, itching, runny nose, and skin rashes. More severe allergic reactions can involve difficulty breathing, swelling of the throat, or even anaphylaxis, a life-threatening condition that requires immediate medical attention.

Allergies can be managed through various methods, including avoiding known allergens, using medications to alleviate symptoms, and in some cases, undergoing allergy shots (immunotherapy) to gradually reduce sensitivity. Identifying and understanding personal triggers is key to effectively managing allergies and improving quality of life.

A severe, potentially life-threatening allergic reaction that occurs rapidly after exposure to an allergen. Symptoms may include difficulty breathing, swelling of the throat, and a drop in blood pressure. Immediate medical attention is required.

An allergic reaction to proteins found in cat saliva, urine, or dander. Symptoms often include sneezing, itchy eyes, and runny nose, as well as skin reactions and asthma exacerbation.

An allergic reaction that occurs when the skin comes into direct contact with an allergen. Common allergens include certain metals, chemicals, and plants, leading to symptoms like rashes and itching.

Also known as cross-reactivity, this occurs when the immune system reacts to proteins in one allergen that are similar to those in another allergen. For example, someone allergic to pollen might also react to certain fruits or vegetables.

An allergic reaction triggered by exposure to cold temperatures. Symptoms can include hives, swelling, and in severe cases, a more serious reaction known as cold urticaria.

An allergic reaction to proteins found in dog saliva, urine, or dander. Similar to cat allergies, it can cause symptoms such as sneezing, itchy eyes, and respiratory issues.

An allergy to the dander or fur of various animals, including cats, dogs, and other pets. Symptoms can range from mild sneezing to severe asthma attacks.

An immune response to specific proteins in certain foods. Common food allergens include peanuts, tree nuts, milk, eggs, and shellfish, with reactions varying from mild symptoms to severe anaphylaxis.

An allergic reaction to tiny mites that live in dust. Symptoms typically include sneezing, runny nose, and itchy eyes, often exacerbated by exposure to dust and allergens in the environment.

An allergic reaction to proteins found in milk and dairy products. This is different from lactose intolerance and can cause symptoms such as hives, stomach cramps, and breathing difficulties.

An allergy to mold spores that can be found both indoors and outdoors. Symptoms include sneezing, nasal congestion, and coughing, and mold can also trigger asthma symptoms.

A common contact allergy to nickel, a metal found in various everyday items such as jewelry, belt buckles, and some clothing fasteners. Symptoms include itching, redness, and rash at the site of contact.

An allergic reaction to nuts, including peanuts and tree nuts (such as almonds, walnuts, and cashews). Symptoms can range from mild to severe, and in some cases, it can lead to anaphylaxis.

An exaggerated response to strong odors or fragrances, which can trigger symptoms such as headaches, nausea, or respiratory issues. This is often seen in individuals with conditions like multiple chemical sensitivity.

Also known as hay fever, this allergy is triggered by pollen from trees, grasses, and weeds. Symptoms include sneezing, runny nose, itchy eyes, and congestion.

An allergic reaction to proteins found in wheat. Symptoms can include skin reactions, gastrointestinal issues, and respiratory problems. It is distinct from celiac disease, which is an autoimmune disorder triggered by gluten.
