Making Hydrochloric acid from sodium chloride

Hydrochloric acid and sodium hydroxide interact and make sodium chloride. is there any way to make Hydrochloric acid from sodium chloride? 

I have low stomach acid, i want to know if i can increase it with sodium chloride or any other method.

    On the chemistry: a lot of energy is released in that reaction, so it is not practical to reverse it. Sodium chloride is an extremely stable compound.

    According to the Wikipedia page, HCl is manufactured on an industrial scale directly from hydrogen and chlorine gas. HCl is more stable than H2 or Cl2 individually, so the reaction is easy to proceed—the opposite of trying to break up NaCl.

    Edit: found the process. It does come from mostly NaCl (in brine/seawater?) but is costly in terms of energy. https://en.m.wikipedia.org/wiki/Chloralkali_process
    ⚠️ I have a lot of ideas, but not much experience! Please keep this in mind when reading my suggestions. ⚠️

    Theoretically, sodium chloride reacts with sulfuric acid to generate HCl gas. Not sure (or wouldn't advise) if this chemistry could be used as an antidote for low stomach acid.

    Adding concentrated sulfuric acid to table salt is actually a common way to produce dry HCl in the lab. And no, it does not work in humans because the patient would dissolve before the salt reacted...
    Try bitter herbs and spices (as tea or seasoning) best ~20 minutes before eating. This helps to stimulate gastric functions.
    Another widespread strategy is betaine hydrochloride.

    Thanks a lot

    Is ginger and pepper considered bitter?
