Does the Brain Shrink During Pregnancy?

By Dave / December 24, 2006

brain-2Yes, the mother’s brain typically shrinks during pregnancy by as much as 8% of its original size.

The brain returns to its normal size about 6 months after delivery.

Researchers have not concluded exactly why this happens but they believe the most likely reason is that the fetus’ need for lipids (fats) is the cause.

The brain is rich in fats and fatty acids.

Many women report becoming forgetful during pregnancy. Perhaps this is why? The fetus pulls all of the materials it needs from the mother to create a healthy human body to house its journey through the world.



Just yesterday, a happy mother of a four-year-old told me of her own experience of becoming foggy headed during pregnancy.

Is there anything that can help?

It’s best to consult with your doctor about what supplements you may or may not take during pregnancy.

Each human body is unique and your doctor will be able to determine what supplements you most need or should avoid based on your own unique characteristics.



If it is true that the fetus is taking fats from the mother’s brain, then perhaps you may consider an EFA or essential fatty acid supplement. You can also eat lots of fish and other foods rich in fatty acids.

Your health care provider may recommend a DHA (docosahexaenoic acid)supplement.

Udo Erasmus has an entire line of EFA (essential fatty acid) supplements. Udo is one guy who has thoroughly researched and understood the need for EFAs in the human body.



Folic acid (a B vitamin) is very important for the creation of the neural tube in the baby. Since this process starts very early in the pregnancy it is useful to take folic acid before becoming pregnant.

I hope you found this information useful. Remember to work with your doctor before, during and after pregnancy. You’ll of course want to have the best care for your developing baby.
