Can zinc deficiency cause mouth ulcers?

Generally, zinc deficiency may lead to mouth ulcers. If necessary, it is recommended to consult a healthcare professional. The detailed explanation is as follows:

Zinc plays an essential role in cellular metabolism and protein synthesis within the human body, particularly in maintaining the normal renewal and repair of oral mucosal cells. When the body lacks zinc, the renewal and repair capacity of oral mucosal cells may be compromised, making them more susceptible to damage and increasing the risk of developing mouth ulcers.

Zinc is also a crucial trace element for the normal functioning of the immune system. A deficiency in zinc can weaken the immune response, making the mouth more vulnerable to infections from bacteria, viruses, and other pathogens. When oral tissues are infected by these pathogens, it can trigger or exacerbate the inflammatory response associated with mouth ulcers. Additionally, zinc deficiency may alter taste perception, leading to reduced appetite, which can further impact nutrient intake, creating a negative cycle that hampers oral mucosal health and delays ulcer healing.

In daily life, it is important to maintain a balanced diet to ensure adequate intake of zinc. Foods rich in zinc include lamb, fish, eggs, beef kidneys, pork liver, and others. Consuming these foods in appropriate amounts can help replenish zinc levels.
