Introduction
Recurrent oral ulcers are often associated with abnormal immune function, nutritional imbalances, high levels of mental stress, poor oral hygiene, or local trauma. For example, deficiencies in B vitamins, vitamin C, and trace elements such as zinc and iron, as well as chronic sleep deprivation and anxiety, may weaken the resistance of the oral mucosa and lead to frequent ulceration.
Recurrent oral ulcers are generally not a specific manifestation of AIDS and cannot be directly linked to it. If concerned, it is recommended to seek professional testing promptly. Detailed analysis is as follows:
Recurrent oral ulcers are commonly associated with abnormal immune function, nutritional imbalances, high levels of psychological stress, poor oral hygiene, or local trauma. For example, deficiencies in B vitamins, vitamin C, and trace elements such as zinc and iron, as well as chronic sleep deprivation and anxiety, may weaken the resistance of the oral mucosa and lead to frequent ulceration. In addition, residual tooth roots, broken crowns, or ill-fitting dental restorations may cause traumatic ulcers.
Although oral ulcers can occur in individuals with HIV/AIDS, they are typically accompanied by systemic symptoms such as persistent fever, swollen lymph nodes, chronic diarrhea, and rapid weight loss. These manifestations are clearly distinct from isolated oral ulcers, and a definitive diagnosis of HIV/AIDS requires blood testing—it cannot be determined based solely on oral symptoms.
If oral ulcers persist or are accompanied by other abnormalities such as unexplained fever or weight loss, prompt medical evaluation is advised, including HIV antibody testing and a comprehensive examination, to identify the underlying cause and receive appropriate treatment.
