With the brain, this process happens early in development, again during puberty, and pregnancy probably reflects another wave of cortical refinement.” Increase in brain white matter during pregnancy
The expensive tissue hypothesis (ETH) relates brain and gut size in evolution (specifically in human evolution).It suggests that in order for an organism to evolve a large brain without a significant increase in basal metabolic rate (as seen in humans), the organism must use less energy on other expensive tissues; the paper introducing the ETH suggests that in humans, this was achieved by ...
Neonatal brain and body size have increased in the hominin lineage, and human maternal investment is greater than expected for a primate of similar body mass. [14] The obstetrical dilemma hypothesis suggests that in order to successfully undergo childbirth, the infant must be born earlier and earlier, thereby making the child increasingly ...

The increase in kidney clearance during pregnancy causes more iodide to be excreted and causes relative iodine deficiency and as a result an increase in thyroid size. Estrogen-stimulated increase in thyroid-binding globulin (TBG) leads to an increase in total thyroxine (T4), but free thyroxine (T4) and triiodothyronine (T3) remain normal. [5]
Diet with exercise may reduce the risk of caesarean section, having a large baby and having a baby with serious breathing problems. [21] Diet and exercise help pregnant women not gain too much weight during pregnancy when compared with giving the women no help to control weight gain or routine care (usually one session in the pregnancy).

Twelve weeks after adding tulisokibart to their current drug regimen, 26% of patients had achieved clinical remission, meaning their symptoms had completely resolved. That rate was 1% in the ...
This diagnosis is generally found in routine fetal anomaly scans at 18–22 weeks gestation. It is one of the more common abnormal brain findings on prenatal ultrasound, occurring in around 1–2 per 1,000 pregnancies. [4] In many cases of mild ventriculomegaly, however, there is resolution of ventriculomegaly during the pregnancy.
