The maternal HPA axis is likely to represent another important link between prenatal insults and developmental abnormalities. The HPA axis is affected by factors such as PNS^129, 130 and infection,¹³¹ which are risk factors for a wide range of neurodevelopmental disorders.^{132, 133, 134, 135, 136} In animal models of early-life postnatal stress, hyper-responsiveness of the HPA axis is coupled with altered visceral pain sensitivity and impaired intestinal barrier function,^137, 138 while aberrant dietary protein:carbohydrate ratios during gestation have moderate long-term effects on the function of the HPA and sympatho-adrenomedullary axes in offspring.¹³⁹ It is useful to note direct responses to in utero stressors such as hypoxia also involve the adrenal system^140, 141 and are essential to fetal survival and neurodevelopment

The gut is deeply connected to the brain. However there are many other factors at play. It is important to consider all factors affecting the brain, and visa versa to understand your symptoms and chronic health conditions.
