There are many causes of oral ulcers, although it is a local mucosal ulceration and pain in the mouth that disrupts the eating habits and daily life of patients. However, the etiology of oral ulcers is quite complex, often involving individual differences. Some patients may have low immunity or genetic factors, and other systemic diseases or environmental factors can also lead to recurrent oral ulcers. In such cases, it is recommended that patients pay attention to diversifying their diet, consume more fresh vegetables and fruits, and avoid frequently eating overly spicy, overly hot, or fried foods, as these can affect the body's metabolism.

In addition, when patients experience severe athlete's foot, this may be related to poor lifestyle habits. Therefore, it's advised that patients pay attention to their habits, change shoes and socks frequently, and wash feet regularly, as these practices can benefit the treatment of athlete's foot.

Moreover, when suffering from athlete's foot, it's crucial to maintain foot hygiene. It is advisable to wear soft cotton socks and ensure that shoes are clean, dry, and well-ventilated. Additionally, patients should focus on boosting their immune system by taking vitamins or mineral supplements, as these can effectively enhance the body’s resistance.
