In this new Keeping Up With The Kardashians sneak peek, Kris Jenner and Kourtney Kardashian are excited to hear how Kim's doctor appointment went and when they hear her news, they're understandably shaken.
Kim tells them that there is more fluid than normal in her placenta, which apparently can only mean two things: A carbohydrate intolerance or something much scarier, gestational diabetes.
Kim is trying not to get hung up on the possibility of the latter, but Kris warns her that it's very serious - in fact, she had it when she was pregnant with Kylie Jenner. "Your life is at stake," Kris warns.
She does admit that it's a wakeup call that things might not be going the way she thought they were and she's going to try to be more healthy.
Other than that scary possibility, Kim says the doctor told her that her baby is in the 95th percentile for height. "I'm like 'are you sure that's my kid?'" she joked (Kim is 5' 3").
Kim's second child is due some time around Christmas.
