I'm currently scratching my head trying to work out how to get some acidity into my stomach without actually ingesting anything, as this solution is out for me due to duodenal ulcers and chronic gastritis, which is in a permanent flare up. PPIs have been pushed by various doctors which of course made me much worse as alchloridia due to PA is the source of this. I found some advice online which I'm going to try and thought I'd share:
Don't drink at least half an hour before and after a meal.
Eat your protein first as you have a greater concentration of acidity as you begin to eat.
Use pink himalayas salt.
Use DGL (licorice)
Try ti gong (a meditative type of exercise which contrates on balancing the body)
In addition to this I'm trying essential oil therapy, eating smaller meals and have just managed to persuade my GP to give me a Vit D3 injection every 3 months. No idea how much of this is 'out there' but to be honest weatern médecine has done nothing but make me worse and even my gastroenterologist supports a more 'naturopath' approach.
