On Twitter, fans blasted Kardashian for continuing her "hardcore workouts" while six months pregnant.
They expressed "concern" for Kardashian's baby.
But Kardashian didn't want to hear it. She quickly called out "social media physicians" for giving their unwarranted advice and commentary.
Kardashian informed her followers that she received the OK from her doctor to continue her workouts.
"My doctor has instructed me to do so," she insisted. "Why does everyone on social media think they are a physician?? Why would I do anything to do that? If you don't know mind your business."
In a follow-up tweet, Kardashian continued to school her followers and linked to an article about excising while pregnant.
"For the ones who think they are physicians all of a sudden ... MY doctor and I communicate and my workouts are cleared and highly recommended," Kardashian added. "Thanks kiddos!"
She encouraged her followers to read a Fit Pregnancy and Baby article that explains why exercising while pregnant is beneficial to both the mother and the baby.
(And it's also "safe." According to the Livestrong Foundation, women who are six months along like Kardashian can still safely maintain their workout routines under their doctor's guidance.)
Kardashian gave a final warning to trolls who think it's their place to comment on her pregnancy.
"Don't make me stop sharing shit," she threatened.
A handful of fans immediately showered Kardashian with their support.
After all, it's *this* type of criticism that made Kardashian hesitant to reveal her pregnancy in the first place.
So let her live (or else she'll "stop sharing shit").
