Women who give birth to babies using in-vitro fertilisation (IVF) are at increased risk of a chronic digestive disease, says a new study.

The researchers from Turkey compared two groups of women who had given birth to their first child at least one year earlier and found that those who had had IVF were three-times more likely to be diagnosed with gastro-oesophageal reflux disease (GORD), than those who had conceived naturally.
