Blood transfusion is the process of transferring blood or blood products taken from a healthy person to a patient who needs it urgently.

Some of the common risks associated with blood transfusion are as follows:
• Fever
• Allergic reactions
• Blood-borne infections like hepatitis B or C, AIDS, etc.
• Acute immune hemolytic reaction

Blood transfusions are done during some surgeries when there is blood loss expected. People with liver disease or severe infections, who do not have adequate blood cells being produced in their body, also need blood transfusions.

An injection is inserted into a vein in your arm. Once inserted, the blood for transfusion is transferred to the body from a blood bag. The amount of blood transferred depends on the condition.

You might experience soreness or bruising for a few days at the site where the IV was inserted for the transfusion. Apart from this, if you do not experience any side effects, then you will feel just as normal as any other time.
