Causes of Angular Cheilitis

Angular cheilitis can have several causes, including:

  • Infections: Fungal or bacterial infections are common culprits. Candida, a type of yeast, is often involved.
  • Nutritional Deficiencies: Lack of certain nutrients, such as iron or B vitamins, can contribute to the development of angular cheilitis.
  • Irritation: Excessive saliva, especially in people who drool or lick their lips frequently, can lead to irritation and cracking.
  • Underlying Health Conditions: Conditions like diabetes or immune system disorders can increase susceptibility to angular cheilitis.

Why It Matters

Angular cheilitis is not just a cosmetic issue. If left untreated, it can lead to secondary infections or indicate an underlying health problem that needs addressing. Identifying and addressing the root cause is crucial for effective treatment.
