Story summary

A retrospective study from Israel finds that chronic maternal hypothyroidism with gestational hypothyroidism may raise autism spectrum disorder (ASD) risk in offspring.
The risk is dose-dependent and rises with affected trimesters.
Adequate treatment of chronic hypothyroidism appears to mitigate this risk.
The study analyzed data from 51,296 women and linked hormonal imbalance across trimesters to higher ASD risk.
Researchers advocate routine monitoring of thyroid hormone levels during pregnancy.
