Acid Reflux

In Western medicine, gastroesophageal reflux disease (GERD) is characterized by the backflow of gastric contents into the esophagus, often resulting in a sour or acidic oral sensation (Vakil et al., 2006, American Journal of Gastroenterology; FDA Guidelines). 

In contrast, Traditional Chinese Medicine (TCM) conceptualizes this phenomenon as "counterflow stomach Qi," attributing it to a myriad of factors. These include excessive carbohydrate consumption leading to 'dampness' (Xue et al., 2010, Journal of Gastroenterology and Hepatology; USDA Dietary Guidelines), emotional imbalances such as stress affecting liver Qi and, consequently, the spleen and stomach (Chan et al., 2015, Evidence-Based Complementary and Alternative Medicine; NIH Research), and the intake of spicy or acidic foods causing "Stomach Fire" (Ness-Jensen et al., 2016, Gut; WHO Recommendations). While TCM provides an alternative lens through which to view GERD, it is important to note that its principles necessitate further validation through rigorous clinical studies (NIH Clinical Trials).
