Myth 1: Donating blood makes you weak for weeks. Fact: The human body replaces the plasma lost in donation within 24 to 48 hours. Red blood cells are fully replenished within 4 to 6 weeks. A healthy adult loses only about 450 ml โ less than 10 percent of their total blood volume โ in one donation. WHO guidelines confirm that a healthy adult can donate safely every 12 weeks. Mild fatigue on donation day is common but severe weakness is not, provided the donor is well-hydrated and has eaten before donating.
Myth 2: People with diseases like diabetes cannot donate. Fact: Well-controlled type 2 diabetics on oral medication โ not insulin โ are eligible to donate in India under NACO guidelines. People with controlled hypertension who are on antihypertensives are also eligible. The eligibility criteria exclude people with haemoglobin below 12.5 grams per decilitre, active infections or fever, recent tattoos, or pregnancy โ not all chronic conditions.
Myth 3: Blood banks misuse donated blood for profit. Fact: Government blood banks in India are prohibited from selling blood. They can charge a processing fee โ typically โน500 to โน1,500 per unit โ to cover testing, storage, and component preparation. Private hospitals pay this fee to blood banks. Transparency in the system is weak, which fuels suspicion, but outright misuse of volunteer donations is rare and criminal.
