Chelsea and Westminster Hospital is taking part in a groundbreaking trial to try and prevent anaemia in pregnant women.

Participants will be given either iron or placebo tablets daily during pregnancy and for six weeks after birth with the results analysed.

Lauren Trepte is Clinical Trials Team Leader for Women’s Health Research at West Middlesex University Hospital in Isleworth.

She explains why anaemia, which affects one in three pregnant women, is such a problem.
