I posted a question regarding bleeding internally, but did not expound on what already has been done. A scope has been put down throat and there is no bleeding in this area. There is no blood in the stool. However feel like could sleep at any time. Am on iron pills because of low iron and do have an appointment with a specialist. But am eager to find out what might be causing loss of blood. Recently donated plasma because prior to tests was feeling good. Wondering if giving blood could have caused this to happen again.
