Allergies occur when the immune system overreacts to harmless substances, known as allergens. These allergens can include pollen, dust mites, pet dander, insect stings, certain foods, and medications. Symptoms vary depending on the type of allergy and the body’s reaction.
Respiratory Symptoms
- Sneezing – A frequent response to airborne allergens like pollen or dust.
- Runny or Stuffy Nose – Also known as allergic rhinitis, often caused by seasonal or environmental allergens.
- Itchy, Watery Eyes – A common reaction to pollen, pet dander, or mold.
- Coughing and Wheezing – Can indicate allergic asthma, often triggered by airborne allergens.
- Shortness of Breath – A severe symptom that may require medical attention.
Skin Symptoms
- Hives (Urticaria) – Raised, itchy red welts that appear suddenly.
- Eczema (Atopic Dermatitis) – Dry, itchy, and inflamed skin, often worsened by allergens.
- Swelling (Angioedema) – Typically affects the face, lips, tongue, or throat and may indicate a serious reaction.
Gastrointestinal Symptoms
- Nausea and Vomiting – Can be triggered by food allergies.
- Diarrhea – Common in allergic reactions to foods like nuts, shellfish, or dairy.
- Abdominal Pain or Cramps – Often seen in food allergies or intolerances.
Severe Allergic Reaction: Anaphylaxis
Anaphylaxis is a life-threatening reaction that requires immediate medical attention. Symptoms include difficulty breathing, severe swelling, low blood pressure, dizziness, and loss of consciousness. Common triggers include peanuts, shellfish, insect stings, and certain medications.
If allergy symptoms persist or worsen, seeking medical advice is essential for proper diagnosis and management.
