Common Myths

Blood donation requires external motivation - most people are easily misled by misconceptions and hesitate to donate blood. Some are scared at the thought of a needle poking their vein to collect blood. Some others feel faint at the sight of blood. Here is some scientific evidence that will clarify most misconceptions. Will I become weak and anemic after donating blood? Donating blood is unlikely to make a person weak or anemic. If the person is already anemic, then the person will not be allowed to donate blood. What happens to the blood I lose? Will I get it back? Blood usually recuperates within 48 hours after blood donation. Usually not more than 350 ml of blood is collected in one donation. This is roughly 7% of the total blood volume in an average healthy person, who has approximately 5 liters of blood. Will I get any disease when I donate? NEVER. Reputed donation centers and blood banks usually use sterile single use bags and needles and have trained staff to handle the process. There is no risk of catching any disease in the process of donating blood. Will my BP go down after donating blood? Some people are anxious during blood donation and their anxiety shows up as a slightly elevated pulse rate. Usually this settles down after in a few minutes. Blood donation does not usually affect blood pressure. Will I feel giddy after donation? Unlikely. The feeling of giddiness is more psychological than physiological. There is no need to be anxious about blood donation. It is safe, easy and painless. Will I lose my red cells in the blood if I donate frequently? No. A person can safely donate blood every 90 days. Donating at regular intervals does not result in loss of haemoglobin or red cells.
