Think iron deficiency only shows up as low haemoglobin? Think again.
In this clip from Episode 13 of the Innersight Podcast, Prof. Vernon Louw, a leading South African clinical haematologist and academic, widely recognised for his expertise in iron deficiency and blood health, explains why haemoglobin is just one piece of the puzzle, and why many people with iron deficiency may go undiagnosed.
Before anaemia even develops, symptoms can include:
• Irritability and anxiety
• Brain fog and poor concentration
• Memory difficulties
• Ongoing fatigue without a clear cause
Relying only on haemoglobin tests can miss early iron deficiency. That’s where ferritin, your body’s iron storage marker, becomes essential for a more accurate picture.
