Research into pregnancy complications

There are specific diseases that can cause complications during and after pregnancy. Read on to find out more, and search our research by specific complications.

We fund research in Tommy's maternal and fetal research centres across the UK to find the causes of miscarriage, stillbirth and premature birth. The conditions below all increase the risk of these outcomes, and that's why we fund research to investigate these conditions and their underlying causes.
