Pregnancy has a lot of do’s and don’ts which can often be overwhelming. It is true especially when it’s your first pregnancy. Imagine things like the endless doctor’s visits, blood tests, sonograms, and nausea. All these can get too much in the first trimester of the pregnancy.

Mercury and pregnancy

A study revealed that a high level of mercury in a pregnant woman’s blood is related to poor cognitive development in children. It’s usually detected when the child clocks three years. This test relied on the measure of a child’s picture vocabulary plus a list of other assessments. These include visual-motor abilities. Such tests helped to come to a conclusion.

A new study discovered that human exposure to mercury happens mainly through consumption of seafood. It is usually methylmercury which forms when mercury mixes with bacteria in the water. This mercury gets absorbed in the placenta.

From here, the mercury transfers to the baby as it grows. It passes through the food eaten by the mother. Prenatal exposure to methylmercury is linked to a variety of problems. These include:

  • Low mean birth weight
  • Risk of preterm delivery
  • Adverse neuropsychological and behavioral effects

A study in Brittany, France observed 2398 women and discovered that those who consumed shellfish were at a higher risk of fetuses with small-for-gestational-age (SGA).

The study discovered a risk of SGA births was 1.33 and 2.14 respectively for women who ate one to four times a month compared to those who had it twice or more in a week. Results were different for those who had it less in a month. This risk doubled for those who ate large crustaceans more than once a month. It’s a different scenario for those who ate different seafood once or less in a month.
