This reaction involves the immune system's overreaction to harmless substances, mediated primarily by Immunoglobulin E (IgE) antibodies 🧬. Upon initial exposure to an allergen, the body produces IgE, which binds to mast cells and basophils—key immune cells involved in allergic responses 🚨. When the allergen is encountered again, it cross-links with the IgE on these cells, triggering them to release histamine and other inflammatory mediators 🧨, leading to symptoms like itching, hives, swelling, nasal congestion, and in severe cases, anaphylaxis—a life-threatening reaction that can cause airway obstruction and shock 🆘. Type I hypersensitivity reactions are common and include conditions such as hay fever, asthma, allergic conjunctivitis, and food allergies 🌽🥜. Diagnosis involves identifying the specific allergen through skin tests, blood tests for IgE levels, or elimination diets. Management typically includes avoiding known allergens, using antihistamines or corticosteroids to reduce symptoms, and, in severe cases, administering epinephrine (EpiPen) for anaphylaxis 💊🛡️. Understanding these reactions is crucial in pathology and immunology, as it helps in developing strategies for prevention, diagnosis, and effective treatment of allergic conditions 🧑‍⚕️. #HypersensitivityType1 #AllergicReaction #ImmediateHypersensitivity #Type1Reaction #IgE #MastCells #HistamineRelease #Allergies #Anaphylaxis #Pathology #Immunology #MedicalEducation #AllergyAwareness #AllergicConditions #ImmuneResponse #Histamine #AllergyManagement #Asthma #HayFever #FoodAllergy #medicalanimations #fmge #fmgevideos #rapidrevisionfmge #fmge2024 #mbbslectures #nationalexitexam #nationalexittest #neetpg #usmlepreparation #usmlestep1 #fmge #usmle #drgbhanuprakash #medicalstudents #medicalstudent #medicalcollege #neetpg2025 #usmleprep #usmlevideos #usmlestep1videos #medicalstudents #neetpgvideos #usmlestep2videos
