Hi! I really enjoy this web site and find it to be very informative. I have had ulcerative colitis off and on for about 16 years. For the last 6-8 months I have not had any bleeding but I have been feeling fatigued, have muscle and joint aches, feel light headed and have dark circles under my eyes. My doctor checked my thyroid function and it was normal. She also measured my ferritin levels which proved to be low normal around 30 mg/dl. My hemoglobin is normal and my G.I. specialist said that he is not worried unless I became anemic. My doctor wanted me to try palafer a high dose iron supplement but because it can cause a lot of constipation and stomach upset, which I already have due to my existing condition, I am nervous about taking it. Instead I am trying to eat more foods rich in iron to try to boost my ferritin levels. But it is confusing when for example pumpkin seeds are supposed to contain about 30% of ones daily iron needs in a quarter cup. But does that mean I will absorb that much. From what I have read a person absorbs only about 10 % of the iron from non heme sources but can double that by eating vitamin c foods. Also I believe we can absorb about 25% of the iron from heme sources, but although I do eat fish and poultry and some beef I don't want to consume too much meat. I realize that for someone like me with gastric issues perhaps I am not absorbing enough iron. But if you could suggest other foods which are high in absorbable iron and explain how much roughly I might expect to absorb I would appreciate it.
