Swelling and turning out of the lower lip may be related to mouth ulcers, lipitis, allergies and other causes.
1. Mouth ulcers: Mouth ulcers located near the edge of the lower lip gradually expand, which may cause the lower lip to be swollen and turned out.
2. Lipitis: due to sun exposure, lip licking and other bad habits and other factors can cause an inflammatory reaction in the lips, resulting in swelling and pain in the lower lip.
3. Allergy: Lip contact with lipstick and other allergenic substances can cause an abnormal immune response, resulting in swelling of the lower lip.
It is recommended that people with swollen lower lips go to the hospital in a timely manner to clarify the cause of the disease and standardize the treatment under the guidance of the doctor, so as not to delay the disease to bring adverse effects on the body.
