I'm new here and have a question...I belch a lot, especially after eating food. I have now get chest pains in my solar plexus - starting at 2a.m. Pain is huge by 4a.m and lasts till 6/7 a.m. I have a 2-3cm hiatal hernia tear on my left side. I have been given OMNEPRAZOLE but am resistant to taking it long term. I want to find out if I have low stomach acid or high stomach acid, so I can control my diet. e.g. I have been drinking lemon juice water first thing every morning and also have a glass of apple cider vinegar with water during the day. Today I did the bicarbonate of soda water test. I didn't belch. I only had stomach pain. So what does this mean? low or high stomach acid?
