[|Human|] does metal valves to the heart, affect your hemoglobin,do the valves break down the red blood cells.my mother is 88, has had her bowel lasered a few weeks ago dew to hemoglobin dropping, she has had 18 bags of blood this year,they dont seem to be  any the wiser
[|AI|]  Hello, Thanks for writing to Chat Doctor, I am Chat Doctor. A metallic valve in the heart does not significantly break red blood cells, to an extent that the person needs 18 pints of blood in a year, there must be some other cause to the blood loss. All patients having a metallic heart valve in place are almost always getting an anticoagulant(blood thinner) which is in most cases Warfarin. This might thin out your blood that that extent that it starts oozing out of minor ulcers or damaged mucosa places of patients stomach and gut. This is probably the case with your mother, She is 88 so not making blood as efficiently as a young person and on the other hand she is losing blood most probably through her gut because of blood thinners. I would advise you to discuss this problem of blood thinners with your doctor, after getting special monitoring tests like INR to see the extent to which blood has got thinned, the doctor can change the dose of warfarin and this can help with blood oozing eventually helping with the symptoms of your mother. I hope this answered your question, If you have more queries I am happy to answer you. Regards.
