Yeh, was considering suggesting Stem Cells and Scar Tissue Removal for the hiatal hernia and that possibility, as it can help some people with pain associated with damage to the oesophagus and digestive tract.
(though the Stomach Healing and Intestine Healing fields will direct stem cells to those specific areas)
The Parasite Destroyer field Dreamy recommended may address some of the contributing factors if GERD is also involved.
The Irritable bowel syndrome field on Patreon may help with GERD and other factors contributing to the constipation and pain as it addresses H. pylori pathogenesis and associated dyspepsia, if the Parasite Destroyer field doesn’t already do this.
Edit: The Vagus Nerve Stimulation field on YouTube can help with GERD and various gastrointestinal tract issues as well.
But didn’t want to include too many other fields if extraneous to Captain_Nemo and @_OM’s suggestions.
What do you think, @_OM?
