Which condition is indicated by insomnia alongside foul breath and sour regurgitation?

The presence of insomnia along with foul breath and sour regurgitation is indicative of food retention. Food retention in Traditional Chinese Medicine (TCM) is characterized by the stagnation of digestive processes, leading to an accumulation of undigested food in the stomach. This condition can manifest as symptoms including sour regurgitation due to the improper digestion of food, foul breath that results from the putrefaction of food materials, and insomnia which can stem from a disturbed digestive function that affects the overall balance of Qi and Yang.

In TCM, insomnia is often linked to disturbances in the Heart and the Shen. When food is not properly digested, it generates excess heat and dampness, leading to an imbalance that can create symptoms such as restlessness and affected sleep quality. Therefore, food retention is the most coherent diagnosis that ties together the presence of these specific symptoms, which reflect a disrupted state predominantly in the digestive system rather than in the more systemic issues associated with fire or liver stagnation.

The other conditions listed, such as ST Fire, LV Fire, and HT Fire, typically present with different accompanying symptoms and are more about heat conditions rather than the accumulation and stagnation of food leading to complications like foul breath.
