Part of it is that kidneys produce erythropoetin, which is a hormone that stimulates red blood cell production in normal people. In kidney disease, this process is diminished.
Also, it is thought that people with some chronic diseases develop what is called "anemia of chronic disease" and it's not clear how this is played out, but it leads to chronic anemia .
Also, people with kidney disease are often fluid over-loaded, and may have a dilutional effect, where the hematocrit and hemoglobin concentration seems lower than it actually is due to so much fluid in the system.
So it's likely due to a combination of the above reasons.
Reduced hemoglobin does not have the oxygen molecules that oxyhemoglobin has. :)

Thalassemia Intermedia is a recessive trait inherited disease of the red blood cells. In thalassemia, the genetic defect results in reduced rate of synthesis of normal hemoglobin chains.
it changes color from red to brown

Many theories have been advanced to account for osteochondrosis, but none has proven fully satisfactory. Stress and ischemia (reduced blood supply) are two of the most commonly mentioned factors. Athletic young children are often.
Low red blood cell (RBC) count or low hemoglobin content are both indicators of types of anemia.With a low RBC count the causes vary, and can include sudden blood loss (as from trauma, including surgery) or an imbalance in the number of red blood cells produced by the bone marrow's reticulocytes versus the number destroyed by hemolysis (natural or disease-induced rupture of red blood cells in the body) or through gradual blood loss (i.e., menstruation in women, or bleeding from a gastric ulcer.)Low hemoglobin content, indicated by a low hematocrittest result, is often the result of iron deficiency, though some chronic diseases can also cause it.
hemoglobin is reduced when the boby is lacking iron which is responsible for the formation of hemoglobin
Thalassemia
Anemia is the medical term meaning the blood has a reduced ability to carry oxygen due to inadequate hemoglobin or red blood cells. Anemia has many different causes, but iron deficiency is a common one.
There are many ways in which a low hemoglobin can occur. Among these include young ladies in their menstruating cycle, pregnant women, blood donating frequently, wounds, nosebleeds, Aplastic Anemia, Cirrhosis, Leukemia, etc. Low hemoglobin usually occurs because the body is too slow to produce more red blood cells, but do not be alarmed yet, go to a doctor before anything. Sometimes a low hemoglobin is actually normal for some people.
