Answer #1

Gastrectomy is the removal of a part or the entire stomach by means of surgery. As a result, there is a considerable decrease in the acidic environment due to lack or absence of HCl, which is a strong acid as well as a reducing agent. Anemia after gastrectomy results due to lack of Fe+2 ions, which are needed to be absorbed by the duodenum. Thus, iron deficiency anemia results due to lack of Fe+ ions getting converted to Fe+2 form, which takes place due to HCl from the stomach.

Thus, correct answer is option no. 2

Low stomach acid results in decreased ability to convert Fe+3 to Fe+2 form.
