Anyone know why IGF-1 wouldn't be increased as well? GHRH is stimulated in hypoglycemic states.

nala_ula  Honestly, it's something that has confused me for a while. Why is it that GH secretion is stimulated by hypoglycemia? I mean, it's literally called growth hormone (for growth!), and hypoglycemia, which is basically a "starvation" state, will stimulate this hormone?
shaeking  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3529368/ This might help answer your question. I basically didn't pick IGF-1 because it would increase the uptake of glucose leading to a worsen hypoglycemic state. Didn't have a true reason otherwise.
temmy  IGF-1 is regulated by insulin. so it will be decreased because insulin levels are also low.
nala_ula  thank you @shaeking!
nwinkelmann  I found this and it also explains to a more genetic/cellular level. Essentially, it says that starvation induces some factors that cause GH resistance and IGF1 suppression.

This is a hypoplasia of the pleuroperitoneal membrane. The guts herniate into the thorax, usually on the left side, and result in hypoplasia of the lungs (because they're horribly compressed).

johnthurtjr  Usually on the left because the liver prevents herniation through the right hemidiaphragm +5

pg32  What's weird to me is that if you usually see air in the intestines on x-ray when they are in the abdomen, why is there no air in the thorax in CDH? The intestines should still have air in them, right? Also, what is filling the abdomen that causes it to appear grayed-out in CDH? +  
drzed  @pg32 You can actually see a gastric bubble if you squint hard enough. Look at where the NG tube is placed; there is a radiolucency to the patient's right of the NG tube which is most likely the stomach. It probably then is radioopaque distally due to the pyloric sphincter, and air having a tendency to rise. +
