After 3 treatments for H Pylori over 2.5 years I think I may be finally free of the bug! fingers crossed

March 23 - 3rd Endoscopy - No Helicobacter seen in Histology only Mild Chronic Inactive Gastritis and LAX LES. No other issues found.

March 23 - CLO test negative and breath test also negative for Helicobacter

Current status
Symptoms - Mainly pain in the upper middle abdominal especially on empty stomach. Sometimes Mild hearburn

The strange thing is I could go for days or if lucky a couple of weeks with no symptoms but something I ate or was bit stressed at workplace and I get flare ups which then lasts for days before calming.

have been on PPI for over 6 months now. Was on pantoprazole 40mg a day but currently on pantoprazole 20mg a day in the morning.

Over 3 years i have tried Omeprazole. Dexilant and now pantoprazole

Hopefully I am free of Helicobacter but my questions are:

1. Has H Pylori messed up my natural acid secretion system such that any change in diet or stress the stomach produces too much acid which then prevents the chronic gastritis from healing? I can sometimes go for weeks without any major digestive symptoms but it always come back if I had something to eat or go through a stressful period at work. When symptoms starts it usually takes a couple of weeks, with the help of PPI and Gaviscon, to calm down

2. Have you seen in people with Mild Chronic Gastritis persisting for a long term post successful helicobacter eradication?

3. Other than PPI what can I use to protect my damaged stomach lining from acid? Are there any medication that would provide quoting for the stomach? Would stomach emptying medication help?

4.Can the inactive chronic gastritis cause so much pain and discomfort?

5. Can stress cause chronic inactive gastritis and h pylori was just a red herring?

Information from.experts and those in similar circumstances would be very helpful
