Are yellow nails a sign of cholestasis i'm 38.4 weeks pregnant?

You should be asking: Your OB that ? Since u are almost ready to deliver, that is your one of your ob's responsibilty to answer all ?S and concerns that you may have like i always do with my OB pts. Your doc can draw liver function, other tests to see if there is a problem. In non pg pts it can be associated with a variety of conditions like bronchiectais, lymphedema and other conditions. If any problems get induced!

Not likely: It is highly unlikely that you are getting yellow nails from cholestasis without also having yellow eyes and skin. Also u would be having some itching as well from cholestasis of pregnancy. There is a condition called yellow nail syndrome which has nothing to do with gallbladder/liver disease. Check with your doc. Congrats on the pregnancy and good luck to you!
