Miscarriage is an all too common occurrence. Some studies suggest that around 1 out of every 5 pregnancies will end in miscarriage. While the vast majority of these will happen before a woman even knows that she is pregnant, many can occur later on in pregnancy as well. While there are a great many things that are known to cause miscarriage, and while it can often be next to impossible to pinpoint the specific cause of an individual miscarriage, experts are confident about some things that are not related to miscarriage. Contrary to some older theories, there does not appear to be any relationship between morning sickness and miscarriage.

Around two thirds of women will experience morning sickness during pregnancy. It was once thought that if you were in the small minority of women who did not experience morning sickness, you would be more likely to have a miscarriage. Others have thought that continual morning sickness could lead to miscarriage. These ideas are unfounded, however. The only remote link between morning sickness and miscarriage seems to be more of a general link between pregnancy symptoms and miscarriage. Some research suggests that women who didn’t experience any pregnancy symptoms such as morning sickness until near the end of their first trimester were more likely to miscarry than women who experienced pregnancy symptoms in the first two to six weeks after conception. Still, this research is new and not entirely conclusive

Instead, there are things that we know to cause miscarriage. Mismanagement of diseases, like diabetes, thyroid problems, kidney disease, and lupus can all contribute to miscarriage. Temporary illnesses such as rubella or bacterial vaginosis can also lead to miscarriage. Certain lifestyle choices can be linked to miscarriage, including things like smoking, alcohol abuse, large caffeine intake, chemical exposure, radiation exposure, and stress. The vast majority of miscarriages, however, care caused due to a chromosomal abnormality of the fetus. In most cases, there is not anything that could have been done to prevent the miscarriage.
