Dr. Rhona Mahony:

It would be impossible and would not be wise to provide a comprehensive list of either conditions that can kill someone or cause adverse health outcomes. The point is that in any clinical course, doctors are able to make sensible clinical decisions that will result in a woman maintaining good health and staying alive. There are times in pregnancy when complications occur that can put a woman's life at risk and can cause serious disorder. The difficulty sometimes is ascertaining the difference between someone being very sick and someone dying. That can be difficult to predict with precision. What doctors and their patients require is the flexibility to work together in the context of clinical disease in pregnancy to make good sound decisions that will ensure that women are safe.
