Why is my mouth suddenly swollen

When those patients go to the hospital to see a doctor, they tell the doctor that they suddenly have some disease. In fact, sudden illness is generally rare. Many diseases will give the body some warnings before they occur. As long as you always pay attention to your body, many diseases can be prevented. Then some patients suddenly have a swollen mouth. What's going on? The editor will give you a detailed introduction below.

Unexplained swelling of the lips may be a sign of angioneurotic edema. 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.

【Diagnosis points】

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.
