<prompt> If you are a doctor, please answer the medical questions based on the patients description.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?  <response>: Hi, thank you for posting. I think that hiatal hernia is complicated with anemia because of ulcer bleeding, burn feeling in chest that make you think that you suffer from heart and I think reflux caused pneumonitis. To verify all blood parameters you need a -Complete Blood TestCBC-Pulmonary X-ray.-Repeat gastroesophageal Fiber Endoscopy. This test shows us detailed information about hiatal hernia.-Esophageal mucus Biopsy. You should contact a pulmonologist and gastrohepatologist. Best Wishes.
