Can gestational diabetes cause autism?

Answered by Jeremy Urbaniak

Gestational diabetes is a condition that affects pregnant women, where their blood sugar levels become too high. It is known to have various health implications for both the mother and the baby. One area of concern that has been investigated is the potential link between gestational diabetes and autism spectrum disorder (ASD).

A study conducted by researchers at the University of California, Davis, found a slightly increased risk of having a child with ASD in women who had gestational diabetes. The study analyzed medical records of over 320,000 children born between 1995 and 2009. It found that women diagnosed with gestational diabetes before 26 weeks of pregnancy had a slightly higher risk of having a child with ASD compared to those without diabetes.

The study reported that the risk of having a child with autism was about 1.5 percent in the general population, while women with gestational diabetes had a risk of a little over 2 percent. Although this increase in risk may seem small, it is still significant when considering the potential impact on individuals and families.

It is worth noting that the study found no increased risk of ASD in women who were diagnosed with diabetes after 26 weeks of pregnancy. This suggests that the timing of the gestational diabetes diagnosis may play a role in the potential association with autism. However, further research is needed to fully understand the mechanisms behind this relationship.

It is important to remember that this study only establishes an association between gestational diabetes and autism, and it does not prove causation. There are likely other factors at play that contribute to the development of ASD. Genetic and environmental influences, for example, are known to be significant contributors to the risk of autism.

While it is concerning to learn about the potential link between gestational diabetes and autism, it is crucial to remember that the majority of women with gestational diabetes do not have children with autism. The overall risk remains relatively low, and the focus should be on managing and treating gestational diabetes to ensure the best outcome for both the mother and the baby.

If you are concerned about the potential impact of gestational diabetes on your child’s development, it is essential to discuss your concerns with your healthcare provider. They can provide personalized advice and support throughout your pregnancy journey.

While there is evidence suggesting a slightly increased risk of having a child with autism in women with gestational diabetes, it is important to remember that the risk remains relatively low. Further research is needed to fully understand the relationship between gestational diabetes and autism, as well as the underlying mechanisms. Managing and treating gestational diabetes should remain a priority to ensure the best possible outcomes for both mother and baby.
