What are the advantages and disadvantages of blood donation?

Q: What are the advantages and disadvantages of blood donation? I have donated blood six times. Is it OK to donate blood every three months?

A:Blood is very important in many medical situations such as serious accidents, organ transplants, major surgery and supporting patients with blood-related disease like haemophilia and thalassaemia. Most hospitals and medical centres are always having a shortage of blood due to a lack of donors which often results in delayed surgeries and treatment, which can lead to complications and even death in patients. Just as you would want aid from other in times of emergency, it is important that we help to save the lives of others as well. A small percentage of first time donors may feel a little dizzy while some may get tingling in the lips and nose and chills, but only for a short while.
