Blood transfusions are needed to treat a number of medical conditions, to replace blood loss during surgery, and for emergency treatment.

Many people lose blood during major operations. Small amounts of blood can be replaced with a salt solution, which your body replaces with new red blood cells over the following weeks. A blood transfusion is required if you lose a large amount of blood. This is very dangerous because it stops the cells of the body getting the oxygen they need to function.

Blood transfusions are only needed for a minority of people having surgery. To reduce your need for a blood transfusion, eat a well balanced diet in the weeks leading up to your operation, and ask your GP for advice about boasting your iron levels.

Transfusions of red blood cells are sometimes used to treat people with anaemia, as well as other conditions where there is a shortage of one component of the blood. Again, this type of transfusion is usually carried out in urgent cases when a rapid improvement is needed. In less urgent cases, treatment by medicines and vitamins may be a better option.

Blood transfusions depend on a number of factors, including your health, medical history, blood type and seriousness of the condition. Your GP will explain to you the advantages and disadvantages of having a blood transfusion, if they feel that you need one.
