Doctor's answer (1)
Dr. Guo Huijie
After weaning, a child may develop mouth ulcers around the lips for several possible reasons. 1. Changes in diet following weaning can lead to spleen and stomach weakness and indigestion, which may result in excessive internal heat or "fire," increasing the risk of mouth ulcers. 2. Deficiencies in certain trace elements and vitamins, such as zinc and vitamin B2, may also contribute to the development of mouth ulcers. 3. Insufficient fluid intake after weaning can negatively affect the health of the oral mucosa. To ensure the child's well-being, parents should adjust the child's diet to maintain balanced nutrition and ensure adequate hydration. If symptoms persist or worsen, prompt medical consultation is recommended.
