Egg white allergy has the potential to recover on its own. Usually, allergic symptoms can subside on their own after stopping the consumption of egg white, but severe allergies need to be treated with medication in a timely manner. Allergies are individual and some people are allergic to egg whites, resulting in rashes, abdominal pain, anorexia and other symptoms. Most allergic patients can recover on their own after avoiding allergens. In severe cases, such as severe diarrhea, vomiting, or even gasping for air, symptomatic treatment is needed immediately, including oral desensitizing drugs such as loratadine and cetirizine. In some children with egg white allergy, as they grow older, the gastrointestinal barrier function is established and the intestinal flora is perfected, the allergic symptoms can be gradually reduced or even self-healed. If a child is still allergic to egg whites after the age of 3, it may become a lifelong disease, but effective avoidance of allergens may not cause related symptoms. Eggs have a high nutritional value, but they are still allergenic for some people, especially infants and young children who are more prone to protein allergies, so parents need to pay close attention when feeding them.
