Did you know that undiagnosed thyroid disorders can affect fertility and the health of mother and baby?

Hundreds of millions of people across the world are currently living with a thyroid disorder,¹ with 1 in 8 women developing thyroid problems in her lifetime.² Yet, there is a staggering lack of knowledge about the impact that thyroid conditions can have on fertility.

A recent international survey revealed a concerning lack of knowledge regarding the impact that thyroid conditions on women, as only a quarter (24%)* of respondents were aware that undiagnosed thyroid disorders can cause fertility problems. In addition, people are unaware of how undiagnosed thyroid disorders during and after pregnancy can have an impact on the mother and baby.

• Less than half of respondents (48%) were not aware that hypothyroidism (an underactive thyroid) could cause complications for the mother and baby during pregnancy.
• Less than half (48%) were aware that it is crucial for pregnant women to check for optimal thyroid hormone levels throughout the pregnancy.
• Only a quarter (26%) of respondents were aware that new mothers who have no previous history of thyroid disease can develop problems with their thyroid within the first year after giving birth.
• Less than half (45%) of respondents were aware that newborn babies (age one month or younger) need to be tested for congenital hypothyroidism in case they are born without a thyroid gland or have an underdeveloped thyroid gland that may require treatment.

Results of the survey indicated that there is a need to better educate people on the possible impact of untreated thyroid disorders on fertility and the health of mothers and babies.
