What causes oral ulcers and dry lips?

Dry lips and oral ulcers may be caused by various factors: 1. Deficiency in vitamin B is a common cause. B vitamins are essential nutrients for maintaining the health of the oral mucosa. A deficiency can impair the growth and repair of epithelial cells in the oral mucosa, leading to oral ulcers and dry lips. 2. Injury to the oral mucosa may also result in these symptoms. Mechanical irritation or chemical damage can trigger local inflammatory responses, affecting the moisture level of the lips. 3. Endocrine imbalances and weakened immune function may indirectly reduce salivary gland secretion, causing dry mouth and thereby increasing the risk of developing oral ulcers. To alleviate these symptoms, it is recommended to maintain adequate fluid intake, follow a balanced diet, and seek medical advice when necessary.
