Kim is due to give birth to her second child, a boy, this month with rapper husband Kanye West. The reality star has been giving honest accounts of her pregnancy journey and she shared another update on her Kim Kardashian West app and website.
The 35-year-old said her "cankles", a term used to describe calves that appear to merge into the ankle, are "out of control".
She also admitted to her struggles at night, saying: "I hardly sleep at all", while revealing she was currently craving barbecue potato crisps.
Keeping Up WIth The Kardashians star Kim and 'Flashing Lights' rapper Kanye are already parents to two-year-old daughter North.
Last week Kim revealed she had undergone a "painful" procedure to turn her breech baby.
Kim has opened up about her pregnancy and weight gain before, revealing to E! News last month: "I just don't think pregnancy and me really agree with each other."
