When patients experience oral ulcers, it may be due to hot weather in the summer or poor diet, leading to loss of appetite and lack of certain nutrients. It is recommended that patients adjust their diets accordingly, consuming light foods and staying hydrated. If patients lack appetite, they can eat some fresh vegetables and fruits to adjust their diet. Additionally, it is crucial for patients to avoid spicy and irritating foods, as these can worsen the ulcers and cause symptoms of heatiness. Therefore, during summer when experiencing oral ulcers, local treatment is also necessary. Topical medications for oral ulcers can be used to help heal the ulcerative lesions.
