Not gaining weight with pregnancy s/p RNY

[Guest guest]

I have a patient who is 19 weeks pregnant, about 1 yr s/p RNY, and

also has PCOS. She has been unable to gain any weight during her

pregnancy. She is 61 " and 180#. She's been eating 3 meals and 3

snacks plus protein drinks. She's even been drinking apple juice.

I suggested she add high calorie things like peanut butter, regular

cottage cheese instead of low fat, smoothies and other drinks that she

can get more calories from.

Any suggestions?

THANKS!
