Trauma or Injury: If there is any kind of trauma or injury to the lips, then there is an inflammatory reaction that is instigated which leads to swelling of the lips.

Other Causes: Other causes of non-allergic sudden lip swellings include orofacial or cheilitis granulomatosa, which is characterized by enlargement of the lips. The onset of the disease is normally initially sudden in nature, but later on it takes a progressively chronic course. The disease eventually leads to large and everted lips. Lip swelling, along with facial swellings, is also seen in Melkersson-Rosenthal syndrome. Angioedema of the lips may also result in lip swelling. Allergic reactions due to certain other syndromes may also occur, but they are very rare.
