主要原因是慢性湿疹和唇部相关感染。营养不良通常不是原因。

该疾病可以单独出现，也可以作为某些更广泛的健康问题（如维生素 B12 或铁水平低引起的贫血）或局部感染（如疱疹和口腔念珠菌病）的一部分出现。唇炎也可能是由于对刺激性或过敏性物质的反应而发生，或者可能由阳光 (actinic cheilitis) 或某些药物（尤其是类维生素A）引发。已报道了几种形式的唇炎 (angular, contact (allergic and irritant) , actinic, glandular, granulomatous, exfoliative and plasma cell cheilitis) 。
The disease may appear as an isolated condition or as part of certain systemic diseases/conditions (such as anemia due to vitamin B12 or iron deficiency) or local infections (e.g., herpes and oral candidiasis). Cheilitis can also be a symptom of a contact reaction to an irritant or allergen, or may be provoked by sun exposure (actinic cheilitis) or drug intake, especially retinoids. Generally, the forms most commonly reported in the literature are angular, contact (allergic and irritant), actinic, glandular, granulomatous, exfoliative and plasma cell cheilitis.

口角炎是一个相当常见的问题，据估计它影响着 0.7% 的人口。它最常发生在30岁至60岁的人群中，在儿童中也相对常见。
口角炎可由感染、刺激引起。感染包括真菌和细菌。在发展中国家，铁和维生素缺乏可能是原因。
○ 治疗 - 非处方药
将非处方抗生素软膏涂抹在病变部位，每天两次，持续数天。嘴唇上反复出现的湿疹可能是嘴唇干裂的主要原因。这种情况，同时治疗湿疹可以预防复发。在发达国家，营养不良很少是原因。
