What is causes cheilosis?

Cheilosis is a condition characterized by inflammation and cracking of the lips. It can be caused by a variety of factors, including:

* Nutritional deficiencies: Cheilosis is often caused by a deficiency of vitamins, such as riboflavin, niacin, or iron. These vitamins are necessary for the production of healthy skin cells and can help prevent cracking of the lips.

* Dehydration: Cheilosis can also be caused by dehydration, which can lead to dry, cracked lips.

* Sun exposure: Excessive sun exposure can damage the skin of the lips and lead to cheilosis.

* Smoking: Smoking can irritate the lips and make them more susceptible to cracking.

* Allergic reactions: Some people may develop cheilosis as a result of an allergic reaction to certain foods, cosmetics, or other products.

* Medications: Certain medications, such as chemotherapy drugs or lithium, can cause cheilosis as a side effect.

* Medical conditions: Some medical conditions, such as Crohn's disease or Sjögren's syndrome, can also lead to cheilosis.

Treatment for cheilosis typically involves identifying and treating the underlying cause. In some cases, over-the-counter lip balms or ointments may be used to help relieve symptoms and protect the lips from further damage. In more severe cases, prescription medications or treatments may be necessary.
