stomach acid

I have been reading from this and other sites that hypothyroidism lower the levels of stomach acid, but this article seems to suggest its the other way around. Any thoughts ?

Metabolic and endocrine effects of metabolic acidosis in humans.

M Wiederkehr, R Krapf

ABSTRACT Metabolic acidosis is an important acid-base disturbance in humans. It is characterised by a primary decrease in body bicarbonate stores and is known to induce multiple endocrine and metabolic alterations.

  • Hi I think you would need to read an awful lot of research papers to evaluate this. In my experience it can do either. When thyroid disease is autoimmune, a lot of other autoimmine conditions may go with it. Some of these are relevant to acid and digestion. Especially autoimmune pancreatitis and also gall bladder which I believe is generally autoimmune. Caeliac disease is too, to name but 3. A lot of Endo`s have worked in metabolic units, I know mine has, and have a particular interest in metabolism because of this link.

    Best wishes,


  • Hi J,

    Thanks for reply. Metabolism, acid, and digestion are things I might find interesting to research when/if my intelligence is restored.

    Its nice to "see" you in good spirits :-)

  • I think that metabolic acidosis refers to acid levels in the blood not the stomach?

    I have Hashimotos (via antibodies) and also have Gastric Parietal antibodies - THIS affects the acid level in ym stomach I believe but my (UK) GP doesnt seem to "get" this!

  • Hi A,

    Thanks for reply, please also see my reply to Galathea

  • Metabolic acidosis means that the ph of the blood is too acid. Leads, I think, to symptoms like gout. Linked to potassium and magnesium levels - at least that is what in the tablets they sell to help correct the problem.

    Its's not the same thing as low stomach aciid.

  • Hi G,

    sorry for the delay in replying, had a couple of being wiped out days.

    Thanks for putting me straight on this, I feel very dumb, I used to have a brain cell ;-)

  • We have all struggled and its an easy mistake to make.. The point of the forum is that we can each contribute our one brain cell and get a massive super brain between us! Xx. G

  • Hi A lot more complicated than that. gout is uric crystals , linked to kidney disease, that is not normally linked to magnesium and Potassium, heart and kidney are as electrolytes.

    Best wishes,


  • When you are hypothyroid every function in the body is slowed down. The impact on skin and hair is well recognised. If you think that the lining of the digestive track is simply another type of "skin" is is obvious that hypothyroid will also have an impact here. The stomach produces less acid meaning that digestion of protein is difficult and food stays in the stomach for longer. Normally the stomach lining replaces itself every 3 or 4 days, but Hypothyroid slows this replacement.

    These factors mean that stomach acid problems are common with hypothyroid.

  • Hi S,

    Thanks for reply, v. interesting about the stomach lining.
