D64.2: Secondary sideroblastic anaemia due to drugs and toxins

Your body is not producing haemoglobin properly. This is caused by certain drugs or toxins.

Blood is made up of blood plasma and blood cells. The blood cells also include red blood cells. They contain haemoglobin, the pigment that gives the blood its red color. This pigment is important for carrying oxygen in the blood. Haemoglobin needs various nutrients to be formed. These nutrients include various proteins, vitamins and iron, for example.

Your body cannot utilize the nutrients for haematosis (blood formation) properly. Although red blood cells are being produced, these red blood cells do not contain enough normal haemoglobin. This means your blood can no longer transport as much oxygen, causing you to feel weak and tired. You may also get breathless or look very pale.
