I have  permission to post on this issue.  I have a pt today, first
baby, with  a hx of what she describes as a "macro tumor" of the
pituitary gland, that  was removed in 2003
She is unsure of any other medical detail.
She is planning to  Breastfeed her baby.  After researching the issue,
I'm more confused  than ever.  Will this affect lactation, and to what
degree?  What  advise should I give her?
Thanks in advance!!
 
Although oxytocin is made in the hypothalamus it is usually delivered to  the 
body via the blood stream from the posterior pituitary gland cells where it  
is stored. It's also found in other parts of the brain.  Will she go into  
labor without oxytocin?  Will she need pitocin? 
 
  If there is no evidence of her body delivering oxytocin when and  where she 
needs it, perhaps an oxytocin nasal spray with produce a let-down.  This 
website talks about mice going into labor with no gene for oxytocin adn  there for 
no oxytocin, but with deficits in milk ejection.
