It’s no secret that studies have linked smoking to low birth weight. But did you know that it may contribute to miscarriages, too?
According to Reuters, a study led by Dr. Sachiko Baba of Osaka University in Japan discovered a concerning statistic. Researchers linked heavy smoking in the early stages of pregnancy to a more-than-double risk of miscarriage in the first trimester.
The study analyzed records related to more than 400 first-trimester miscarriages. It was discovered that those who smoked heavily during pregnancy (20 cigs or more per day) had two times the risk of miscarriage when compared to nonsmokers.
According to Web MD, a number of environmental hazards may increase the risk of miscarriage. For starters, lead is thought to contribute to this risk. This involves lead found in water pipes used in homes constructed before 1978 and the use of lead paint.
Web MD also warns that chemicals found in common items may be of concern. These can include paint thinners, degreasers, stain or varnish removers and pesticides. Others also say that chemicals associated with fracking may pose a risk.
According to Healthline, obesity increases the risk of miscarriage in pregnant women. This may elevate the likelihood of fetal problems such as spina bifida, cardiovascular problems, hydrocephaly and cleft palate. Further, it increases the risk of gestational diabetes and high blood pressure.
