Unfortunately, I don't think so.
As we've learned in science and biology in school, our body has the ability to keep things in balance, which is called homeostasis.
For the stomach, it's natural environment is acidic (which helps in digestion of food / killing of bacteria/germs). Trying to "alkalize" it is pointless.

P.S. Same goes to oxygenated water which was the craze way back when, our stomach doesn't absorb oxygen. Just a scam in my opinion.

So need to avoid ulcer again. Else it will turn into cancer?
If I have mouth ulcer repeatedly, I will get mouth cancer too? 😥
Scary ya. Ulcer sound so benign. Yet so deadly.

my late grandpa died due to stomach ulcer
he was 83 years old that time
Dr said too risky to undergo operation
that was 17 years ago

Thanks bro.

Additional point, don't think only acid can do damage to the body.

Alkaline burns are worse compared to acid burns on your skin / eye. 

People always think ACID = corrossive. True but other stuffs can be worse.

Wokey. By the way, is vater = Father? I am learning German now

Fap can die?

Yes. Ideally. That’s why they prescribe you with stuff like weeks of pantoprazole or other classes of acid reducing drug together with h pylori eradication therapy with hope to kill h pylori and allow time for ulcer to heal.
If same spot ulcer then higher chance lo.

Yes. Imagine fap until kena psychogenic shock and die with your hand holding your didi. Malu sial
