Gastroesophageal reflux disease（ GERD） is common in clinic.Based on the theory of Qi movement

we discuss its pathogenesis in three aspects: liver Qi invading the stomach

spleen-stomach disharmony

and lung failing to govern descent.Its treatment in Chinese medicine focuses on regulating Qi movement

and the therapeutic principle is to harmonize the stomach and direct reflux downward.Assisted by soothing the liver

fortifying the spleen

and diffusing the lung

the Qi movement（ ascending

descending

exiting and entering） among the viscera could be harmonized

thus the Qi movement all over the body could be harmonized

and all symptoms could be healed.
