I have had an ongoing issue with my blood iron levels for about a year now. Despite taking iron supplements as directed by my hematologist, my iron level is 25 - half of the normal according to my doctor. I take Prilosec daily for heartburn (again, as directed by my doctor), as well as an iron supplement and folic acid supplement. I have a small hiatal hernia which my doctor suspects may be responsible for a slow bleed. I had a colonoscopy and endoscopy within the past three years, both of which reflected no problems. I experience bloating and diarrhea on a frequent basis. Any advice for me?
