The Oral-Gut Axis: A Key Player in Long COVID
A comprehensive review of over 300 studies strengthens the case for an "oral-gut axis" linking periodontitis and inflammatory bowel disease (IBD). The review highlights the reciprocal relationship between the two conditions and emphasizes the need for collaborative, holistic health care for patients. Risk factors for periodontitis include advanced age, diabetes, genetic factors, certain medications, poor oral hygiene, and smoking. The spread of periodontitis pathogens and systemic inflammation may contribute to other health issues such as diabetes, heart disease, and preterm birth. The review calls for further longitudinal studies and collaboration among health care professionals to provide comprehensive oral-systemic health care.
