My problem can be easily described. I suffer from a continuous reduction of hemoglobin. Every day I have to take iron supplement to retain my hemoglobin levels in normal range.
I give you an example of my condition. Let’s say I take an iron supplement for a year, the blood analysis confirms hemoglobin level at 146 g / l. Subsequently I cease to take an iron supplement. Two months later hemoglobin level falls to 97 g / l. I could give you several similar examples during previous 6 years.
Then I always start to take iron supplement again and my hemoglobin levels come back to the normal. If I take iron every day, hemoglobin levels remain within normal limits. Basically, I must constantly take the iron supplements.
I believe that the absorption of iron by my guts should be fine though. Hematologist said that when my hemoglobin levels are increased after taking iron supplements, absorption should be fine. Also, when I took iron tablet at night on an empty stomach, my GP confirmed after the blood analysis that I had elevated levels of serum iron (that was also independently confirmed by another doctor a year later).
I do not suffer from celiac disease. I should not suffer from an increased destruction of red blood cells, bilirubin levels are normal. I am not a vegetarian. I have no intestinal parasites. The amount of vitamin B12 and other blood parameters are in normal ranges.
These problems started about 6 years ago, before that I did not need to constantly take iron supplements.
I would like to ask you few questions:
1. May I have some form of iron malabsorption considering the fact that my body is able to absorb sufficient amounts of iron from the supplements but not from normal diet?
Note .: My sibling eats almost the same food as I but his hemoglobin levels are absolutely all right, without need of taking iron supplements.
2. What various conditions or illnesses should I have?
3. What can cause so massive decreasing of hemoglobin levels? Where do I lose it, if I do not bleed?
