I can understand your concern. You may have some chronic blood loss due to ulcer.  You should take treatment of that first.  For low ferritin level you can take oral iron supplements like ferrous sulfate or ferrous fumarate. Or injectable iron like iron extra or iron sucrose. You should take iron rich food like dates, green leafy vegetables, Chat Doctor.  Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
