Hello again. Just thought I would re-post this on a new thread. I would add only that today I discovered on the Wikipedia entry for PA that there is a link between the bacterium Helicobacter pylori and PA. I have just been diagnosed with having this bacterium, though it is now inactive. Has anyone else out there any experience of this ? Original post below.
About 7 months ago I started showing symptoms such as brain fog, loss of balance, fatigue, chest pains, minor speech problems. But none of the other physical problems I have read about on this site such as tingling hands/feet etc. Started taking sublingual drops of B12 in mid January only (SOLGAR, 2000mg a day). Within a couple of weeks I felt much better, and a week or so later I think all symptoms had gone. I then reduced daily B12 to 1000mg a day. About 2 weeks ago symptoms started to return so I went back on the the higher dose. Unfortunately I still have the fog, balance problems and now daily headaches. I have seen several doctors here in Moscow, including 2 gastroenterologists and a neurologist. None of them know anything about B12 deficiency and didn't want to hear my opinions, based largely on what I have read on this site. I have now arranged to have an Intrinsic Factor test at another clinic tomorrow. I asked for a stomach test - to check for low acid. They did a test but I then discovered it had nothing to do with acid - it checked for about 8 other common stomach problems. Only interesting finding was that my stomach contains a bacterium called Helicobacter pylori IgG, though it is now 'in remission' (not active). In the absence of any scientific test for low acid I conducted my own test at home: a quarter teaspoonful of baking soda in water, then waiting for burping - which should occur in a couple of minutes if acid level is normal. I waited for over 5 minutes but no burping at all.
My questions therefore are these:
I am now back on 2000mg a day of sublingual B12 but still symptoms of brain fog etc. Is it possible that the sublingual has just stopped working or is less effective? The one bit of really good news for me is that the chest pains went shortly after starting the B12 and have never come back. Is it possible that the sublingual B12 helps up to a point but is not the complete answer?
If low stomach acid is the problem - is this also considered PA?
Is it possible that my symptoms suggest some other problem, unrelated to PA?
Many thanks to all the knowledgeable people on this site for all your help!
