Her posts began with the model discussing her long-term suffering with Hashimoto's disease, which she revealed to the public for the first time in December 2016. "I was also part of a holistic medical trial that helped my thyroid levels balance out", she continued. "Don't listen to mean people", one wrote, while another noted "I learned to love my body the way it is, to love the fact that we all have different bodies, to care less if someone says I'm too thin and to stay healthy even if the circumstances make it hard".
Earlier in the day she took to Twitter to address her health, calling out those who were 'so determined to come up with why my body has changed over the years'.
She also put a stop to any alleged drug use. "Use your energy to lift those that you admire rather than be cruel to those you don't".
The model's followers flocked to the comments section to lend their support, with stars such as Ruby Rose and Chrissy Teigen standing by their star friend, perhaps because both have faced similar online trolling about their figures.
Victoria's Secret model Lily Aldridge responded writing: "I love you! And just FYI for everyone the last meal I had with G was a FULLLLY LOADED KFC FEAST".
"Those of you who called me "too big for the industry" were seeing inflammation & water retention due to that".
"Although stress & excessive travel can also affect the body, I have always eaten the same, my body just handles it differently now that my health is better", she explained.
After explaining the changes her body went through, Hadid points out that she shouldn't have to defend her body, especially to people expecting a certain standard for beauty or sex appeal and simply do not understand the changes her body have developed with her medication.
Gigi's post ended with a plea for social media users and fans to have more empathy with others rather than judging those they don't know.
"My metabolism actually changed like insane this year", she shared at the time.
HollywoodLifers, what do you think of Gigi's response to the body-shamers?
