Age 37, Female Symptoms
Hi, dear. I have gone through your question. I can understand your concern. You have polyp and ulcers in your colon that leads to chronic blood loss. It leads to iron deficiency anemia and low ferritin level.  You should go for surgery of your polyp and take treatment of your ulcer. Once the blood loss will stop. Your anemia and ferritin level will increase.  You can also take oral or injectable iron to improve ferritin level. 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.
