can muscles rebuild after beriberi?
 

I know this is a rare disease in the US, but I got beriberi from vitamin deficiency in relation to Celiac Disease. It wasted some muscles in my back and stomach. Does anyone know what the recovery expectation for muscles is, or what can help?

I beleive yes..
 

Just look at all the wasted muscles in alcoholics! Once they get off the alcohol,and improve nutrition and lifestyle they can go back to normal.

You obviously should be taking theraputic doses of Thiamin and other B vitamins like B12. Also Magnesium/calcium & D3 formulation.

You may need some PT and some strenghth training. It won't happen overnight, but it will happen. I also have a bad back, and understand the extra challenge involved.

Yes, but it will be so gradual that from week to week you won't notice it.
