What is fever of unknown origin?
Fever of unknown origin (FUO) is a condition characterized by a persistent fever without an identifiable cause after thorough medical evaluation. This condition is typically defined by a fever lasting more than three weeks, with temperatures exceeding 38.3°C (101°F) on several occasions, and where the underlying cause remains elusive despite extensive diagnostic efforts. It presents a challenging scenario for healthcare providers as it requires a broad differential diagnosis and often involves multidisciplinary management.
How does TCM view fever of unknown origin?
Traditional Chinese Medicine (TCM) views fever of unknown origin as a manifestation of internal disharmony, often linked to various patterns of imbalance within the body. Unlike Western medicine, which seeks a specific pathogen or disease process, TCM emphasizes the importance of understanding the body's overall condition and its interplay of energies. Identifying the correct pattern of disharmony is crucial in TCM, as it forms the basis for personalized treatment strategies that aim to restore balance and alleviate symptoms.
Causes of fever of unknown origin according to TCM
In TCM, fever of unknown origin can stem from various patterns of disharmony. One prevalent cause is Stomach and Spleen Qi Deficiency, where the digestive system's weakened state fails to regulate body temperature effectively, leading to persistent fevers. Another potential cause is Full Heat with Yin Deficiency, where excessive internal heat depletes the body's Yin, causing prolonged fever and associated symptoms. These patterns underscore the importance of a holistic approach in TCM, focusing on restoring balance within the body's internal energies.
