What causes the child's upper lip to swell suddenly?

In life, the most feared thing is some sudden illness, which will make people at a loss, especially children who cannot express their feelings, which is even more difficult. This requires parents to pay more attention and learn more about this aspect. Why does my child’s upper lip suddenly swell? Today I will tell you why children’s upper lip suddenly swells.

Swelling of lips for no reason may be angioedema. Angioedema is mainly an allergic reaction limited to the skin and subcutaneous tissue, which can be caused by drug allergies, insect stings, desensitization injections or eating certain foods (especially eggs, shells, and nuts). It is a temporary, localized, painless subcutaneous or submucosal edema. The main cause of the disease is type I allergic reaction caused by foreign proteins or drugs.

① It is more common in the loose connective tissue around the lips, more often in the upper lip than in the lower lip.

② The swelling develops rapidly and is obvious within 10 minutes. The edema area is bright and flushed, painless but with a feeling of distension, burning and itching. The swelling may last for several hours or may subside within 1 to 2 days.

③ Edema is most common in the upper lip, manifested as thickening and protruding upper lip, or limited to the upper lip-nose wing area. If it occurs on the tongue or palate, it may cause temporary language and eating disorders. Severe edema can spread to the floor of the mouth and throat, causing breathing difficulties. 【Treatment principles】① Quickly identify and eliminate allergens. ② Apply calamine lotion on lips to protect skin and relieve itching. ③ Use antihistamines and corticosteroids if necessary. ④ Pay attention to cases where the disease spreads to the oropharynx and causes breathing difficulties, and perform preventive tracheotomy if necessary.
