Latex allergies occur when the immune system reacts to proteins found in natural rubber latex, which is commonly used in products like gloves, balloons, and condoms. Symptoms can range from mild skin irritation to severe reactions, such as difficulty breathing or anaphylaxis. People at higher risk include those with frequent exposure to latex, such as healthcare workers and individuals with certain medical conditions. Diagnosis typically involves a medical history review and allergy testing. Avoiding latex products and using alternatives, like nitrile or vinyl, can help manage the allergy effectively.
