Patients who frequently develop recurrent oral ulcers may have underlying vitamin deficiencies. Deficiency in vitamin C or B vitamins—particularly B2 (riboflavin), B6 (pyridoxine), B9 (folate), and B12 (cobalamin)—can contribute to the development of oral ulcers. A definitive diagnosis requires clinical evaluation, including trace element testing at a hospital, for comprehensive assessment. In daily life, patients should increase their intake of vitamin-rich foods. Additionally, regular physical exercise is recommended to enhance overall immune resistance.
