No. A hiatal hernia is an enlargement of the normal hole in the diaphragm muscle through which the esophagus passes to enter into the abdominal cavity. Acupuncture would have no effect on this anatomical abnormality.
Hiatal hernia. I agree with the previous responders. Auricular acupuncture can be used to treat some symptoms related to a hernia but it can not fix a hernia. If you believe you have a hiatal hernia - please seek surgical evaluation.
