Anaphylaxis: Anaphylaxis is a severe, life-threatening allergic reaction that can occur rapidly after exposure to an allergen or in some rare instances without an external trigger. Symptoms include difficulty breathing, swelling of the throat, hives, gastrointestinal symptoms and a drop in blood pressure. Immediate medical attention is crucial.
Angioedema: Angioedema is characterized by deep swelling beneath the skin, often around the eyes and lips. It can be caused by allergies, medications, or genetic factors.
Aspirin-exacerbated respiratory disease (AERD): AERD is a condition where aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) trigger severe respiratory symptoms in individuals with asthma and nasal polyps.
Asthma: Asthma is a chronic respiratory condition characterized by airway inflammation, bronchoconstriction, and difficulty breathing. Allergens can trigger asthma attacks.
Atopic dermatitis: Also known as eczema, atopic dermatitis causes itchy, inflamed skin. It often occurs in people with a family history of allergies.
Drug allergy: Some individuals develop allergic reactions to specific medications, leading to symptoms like rash, hives, or even anaphylaxis.
Chemotherapy reactions: Allergists may manage allergic reactions to chemotherapy drugs, which can cause skin rashes, itching, or other symptoms.
Environmental allergies: These include allergies to pollen, dust mites, pet dander, and mold. Symptoms can affect the respiratory system, skin, or eyes.
Eosinophilic disorders: These conditions involve an abnormal increase in eosinophils (a type of white blood cell) and can affect various organs.
Eosinophilic esophagitis: An inflammatory condition of the esophagus characterized by difficulty swallowing and food impaction.
Hyper eosinophilic syndrome: A rare disorder where eosinophils accumulate in tissues, leading to organ damage.
Food allergy: Allergists diagnose and manage food allergies, which can cause symptoms ranging from mild hives to severe anaphylaxis.
Immunodeficiencies: These are conditions where the immune system is weakened, making individuals susceptible to infections.
Mastocytosis: A disorder involving excessive mast cells, which release histamine and other chemicals, leading to symptoms like flushing, itching, and abdominal pain.
Nasal polyposis: Noncancerous growths in the nasal passages that can cause congestion and difficulty breathing.
Sinusitis: Inflammation of the sinuses, often triggered by allergies or infections. This condition can be acute or chronic.
Urticaria (hives): Raised, itchy welts on the skin caused by allergic reactions.
Venom allergy: Allergic reactions to insect stings or bites, such as those from bees, wasps, or ants.
