In Chinese Acupuncture acid reflux, nausea, vomiting and even hiccups are direct results of an imbalanced weak stomach. These pathologies are mainly of the stomach, but other organs and their associated meridians can also affect and cause these pathologies, but the stomach is the main focus.
The term most acupuncturists use to describe these issues is
rebellious stomach qi/energy, a healthy strong stomach allows for its qi to
descend downward. When there is a deficiency or excess affecting the stomach
then the energy goes up and rebels against its natural pathway.
