I have addressed this type of anemia (aka B-12 deficiency) several times in here. I had gastric bypass which made me B-12 deficient or pernicious anemic and yes it had a horrible result on my milk supply. There are quite a few studies now showing a link between B-12 deficiency and low B-12 in the mother's milk supply. I can't find any actual studies persay on the effects on milk supply itself, but have talked to several RD's who work with gastric bypass patients that seem to have the same issues with milk supply with B-12 deficiency (or pernicious anemia) Please have this mom get some B-12 supplementation. Also, may be pertinent to have baby's B-12 level drawn to make sure the baby is not also anemic. This can have devastating neurological consequences for a baby. Even though your mom in question may have never had a gastric bypass, the common thread is the B-12 deficiency, something I am familiar with. You may email me privately if any other questions. As a sidebar...I was looking at pics of my baby the other day, while she was so thin from my low milk supply...she was so scrawny, I thank heaven everyday for the wonderful milk donor who saved my baby's life while I "fixed" my issues with B-12 supplementation...she is good and fat now...truly a miracle.
