Thank you all for responding! So appreciated. When something alters your life like this you want to try anything to get it back. My blood test revealed I was low in iron and vit K. Waiting for the urine test now to see what that shows. My functional doc wants to make sure I get the gut in shape to absorb nutrients normally, as like you said this can be really altered from the surgery. Taking Betaine HCL which is an acid additive, the premise being the system doesn't produce enough of this to break down foods. Trying not to be too scared with all this, as I said I have just never felt the tiredness/weakness to this degree in all my 56 years of life.
