Women who are underweight before they become pregnant are 72 % more likely to have a miscarriage in the first three months of pregnancy, according to a study from the London school of Hygiene & Tropical Medicine.

The study involved more than 6,600 women, aged 18-55. In this same study it was found that underweight women can significantly reduce their risk of miscarriage in the first trimester by about 50% by taking supplements with folate and iron and by eating a healthy diet with fresh fruits and vegetables.
