He SAYS...most of stomach gone means most of intrinsic factor gone and this will just be part of my life from now on. I was always "borderline anemic," losing stomach tissue made it worse.
Not as bad as an RnY would have made it...but it is worse than in my earlier life...when they just didn't let me donate blood.
AFAIK, I'm not bleeding anywhere...I've had a half dozen colonoscopies that confirm that and there wasn't even trace blood in the last UA, unusual for me. So...I just don't absorb enough because I don't have, according to him, enough stomach acid, due to insufficient intrinsic factor. Although my reflux-y evenings might be enough to counter that position.
This makes no sense to me. Intrinsic factor is needed to take up B12, not iron. http://en.wikipedia.org/wiki/Intrinsic_factor
If your doctor said this, I worry whether he knows shit about what he's talking about.
Here is something particularly interesting: http://en.wikipedia.org/wiki/Iron_deficiency
Bioavailability and bacterial infection[edit]
Iron is needed for bacterial growth making its bioavailability an important factor in controlling infection.[20] Blood plasma as a result carries iron tightly bound to transferrin, which is taken up by cells by endocytosing transferring, thus preventing its access to bacteria.[21] Between 15 and 20 percent of the protein content inhuman milk consists of lactoferrin[22] that binds iron. As a comparison, in cow's milk, this is only 2 percent. As a result, breast fed babies have fewer infections.[21]Lactoferrin is also concentrated in tears, saliva and at wounds to bind iron to limit bacterial growth. Egg white contains 12% conalbumin to withhold it from bacteria that get through the egg shell (for this reason prior to antibiotics, egg white was used to treat infections).[23]
To reduce bacterial growth, plasma concentrations of iron are lowered in a variety of systemic inflammatory states due to increased production of hepcidin which is mainly released by the liver in response to increased production of pro-inflammatory cytokines such as Interleukin-6. This functional iron deficiency will resolve once the source of inflammation is rectified, however if not resolved it can progress to Anaemia of Chronic Inflammation. The underlying inflammation can be caused by fever,[24]Inflammatory Bowel Disease, infections, Chronic Heart Failure (CHF), carcinomas and following surgery.
Reflecting this link between iron bioavailability and bacterial growth, the taking of oral iron supplements causes a relative over abundance of iron that can alter the types of bacteria that are present within the gut. There have been concerns regarding parenteral iron being administered whilst bacteremia is present, although this has not been borne out in clinical practice. A moderate iron deficiency, in contrast, can provide protection against acute infection, especially against organisms that reside within hepatocytes and macrophages such as Malaria and TB. This is mainly beneficial in regions with a high prevalence of these diseases and where standard treatment is unavailable.
