Are overweight and obese persons more prone to iron deficiency?

Various population based studies have shown associations between higher BMI and lower iron status and anaemia. We have shown this for example for Mexican women and children. It may well be that this is due to lower iron absorption induced by inflammatory processes.

In this project, we firstly assess iron absorption over a range of BMI’s. In addition, we compare the enhancing effect of ascorbic acid on iron absorption between BMI groups. Secondly, we assess iron absorption in obese subjects before and after weight loss through bariatric surgery. This study takes place in collaboration with the University of Monterrey in Mexico. With this, we aim to better understand the underlying processes that explain lower iron status in relation to obesity.
