Your stomach lining is destroyed, even though the bacteria is dead.
Killing H. Pylori and healing your stomach are two completely different things. You only did one.
H. Pylori survives your stomach acid by burrowing into the mucosal lining — the thick protective coating separating your stomach wall from everything you eat. To survive, it secretes enzymes that dissolve this lining, produces ammonia that inflames the tissue, and disrupts the cells responsible for producing fresh mucus. Over months and years, it strips away the very thing protecting you.
But you knew this already didn't you. That's why the gnawing and burn don't stop. That's why it even reaches your back.
Then triple therapy killed the bacteria. The test came back negative. The doctor said congratulations.
What you are left with is an open battlefield. No invader. But no protection either. Raw, inflamed, exposed tissue with nothing standing between your stomach acid and your stomach wall.
Every drop of acid lands on unprotected, damaged cells. Every meal is salt on an open wound.The bacteria did its damage and was eliminated. But you were sent home without anyone addressing what it left behind.
"Give it time" is not a treatment protocol. It's really just a guess.
