For millions of women around the world, persistent exhaustion is treated not as a medical red flag, but as an inevitable tax on daily life. Between balancing careers, family responsibilities, and social obligations, feeling constantly drained is frequently normalised, brushed off as burnout, or dismissed as ordinary stress. Yet beneath this pervasive culture of ‘just pushing through’ lies a widespread, under-diagnosed physiological condition: chronic iron deficiency.

Iron is a foundational element required to manufacture haemoglobin—the vital protein in red blood cells that transports oxygen from the lungs to every cell and organ in the body. When iron levels dwindle, haemoglobin production drops, leaving the body starved for oxygen. Despite its critical role, iron deficiency remains one of the most routinely overlooked health crises in women's medicine, leaving patients stuck in a multi-year cycle of debilitating fatigue. To unpack why this condition is so frequently missed, how to navigate diagnostic blind spots, and what actionable steps women can take to reclaim their vitality, two Indian health experts in haematology break down the science behind the iron deficiency trap.
