Allergies: What You Need to Know
Allergies are a common health issue, affecting up to 30% of the population. Allergies occur when the body has an abnormal reaction to a substance that is normally harmless. These substances, called allergens, can include pollen, dust, pet dander, mold, and certain foods. When exposed to an allergen, a person's immune system produces antibodies that cause the release of chemicals, such as histamine, which lead to allergy symptoms.
Symptoms of allergies can include sneezing, itching, watery eyes, coughing, and difficulty breathing. In some cases, allergies can cause serious reactions, such as anaphylaxis.
Treatment for allergies typically involves avoiding the allergen, if possible, and managing symptoms with medications, such as antihistamines and nasal sprays. In some cases, allergy shots may be recommended.
Will my allergies improve over time? Allergies are an ongoing health condition, and there is no cure. However, some people may experience an improvement in symptoms over time. Factors that can influence the course of allergies include age, the severity of the allergy, and changes in the environment or lifestyle. For example, if you move to an area with a lower pollen count or reduce your exposure to dust or pet dander, your allergies may improve.
