On World Blood Donor Day, observed every year on June 14, the spotlight turns to the vital act of blood donation—an effort that saves millions of lives each year. Yet, many potential donors still hold back due to confusion or misinformation. To help clear the air, we spoke to Dr. Sangeeta Pathak, Director and Head of Transfusion Medicine at Max Super Speciality Hospital, Saket, about the do’s and don’ts of blood donation. Here’s what we learned.ALSO READ: Who Can Donate Blood To Whom?Can Women Donate Blood During Their Period?This is one of the most common concerns, especially among first-time female donors. According to Dr. Pathak, as per the Drugs and Cosmetics Act, women are advised not to donate during their menstruation, particularly during the 4-5 days of active bleeding. However, they are completely eligible to donate at any other time of the month if they are in good health.What If You’re Recovering from Illness or Taking Medication?Health is key when it comes to blood donation. “A person should be completely healthy and free from fever or illness at the time of donation,” says Dr. Pathak. Moreover, certain medications can lead to deferral, and there is a comprehensive list maintained under the Drugs and Cosmetics Act. So if you’re on a prescribed course, it’s best to consult a doctor or the blood bank before donating.Alcohol, Smoking and Blood Donation—What’s the Deal?While an occasional drinker may not be entirely disqualified, heavy alcohol consumption is a red flag. “Anyone who is under the influence or shows signs of intoxication should not be donating blood,” Dr. Pathak warns. Ideally, toxic substances like alcohol or nicotine should be avoided for several hours before donation, and if there is an emergency and the only available donor has consumed alcohol recently, it's safest to look for another eligible person.Basic Eligibility: Age, Weight, and HealthTo donate blood in India, you must be:18 to 65 years old (first-time donors should not be older than 60)Weigh at least 45 kg (for 350 ml of whole blood)Hemoglobin levels of at least 12.5 gm/dlFor apheresis (platelet or plasma donation), the minimum weight is 50 kg, and the age range is 18 to 60 years. Chronic illnesses and poor general health are automatic grounds for deferral.Tattoos and Piercings: Are You Temporarily Ineligible?Yes.

This is a precautionary step to ensure there’s no risk of transmitting infections.TO KNOW MORE, READ: How Long After a Tattoo or Piercing Can I Donate Blood?What to Eat (or Avoid) Before and After DonationA proper meal before donating is important, but fasting is not advised. “The donor should not be on an empty stomach, and their last meal should be at least four hours before donation,” explains Dr. Pathak. Avoid fatty foods before donating as they can interfere with blood testing. After donation, staying hydrated and consuming a light snack helps restore energy levels quickly.A Note on Low HemoglobinWomen, especially, often have concerns about low hemoglobin levels. If your levels are below 12.5 gm/dl, you won’t be allowed to donate—for your own safety.
