Sarahin, thanks for sharing the info. She has hypothyroidism , but I am not sure what is the cause of the disease , will ask doc in our next visit.
So what did you do for heavy periods , is there any medication to help reduce that ??That is major cause of weakness .

Rose, yes you are right I read about that too autoimmune disease leading to malabsorption of b12.

By the way, in latest test B12 level increased from 205 to 322 , is that a good increase in one months period ? will it be considered that she is not suffering from malabsorption???

Thanks.
