Allergies
Allergies occur when the immune system reacts to substances that are normally harmless to most people. These substances, known as allergens, can include things like pollen, dust mites, pet dander, certain foods, and insect stings. The immune system mistakenly identifies these allergens as threats and releases chemicals such as histamines, leading to various symptoms.
Common symptoms of allergies can include sneezing, itching, skin rashes, swelling, and even difficulty breathing. These reactions can vary in intensity from mild to severe. In some cases, exposure to an allergen can trigger a life-threatening condition called anaphylaxis, requiring immediate medical attention.
Allergies can affect anyone, regardless of age, although some people might be more prone to developing them due to genetic factors. While there is no cure for allergies, they can often be managed with treatments like antihistamines or other medications, as well as lifestyle changes to avoid triggers. It's important to consult a healthcare professional for an accurate diagnosis and management plan.
