She added: "I’ve always been a curvy girl & I really wanted to enhance my shape that I already had, but I just couldn’t naturally achieve the dream body I was after no matter how hard I dieted or exercised due to my age (42) & hormones. Surgery was a serious decision & one that I researched for more than a year.
"I decided to take the plunge... I had Vaser liposuction on my arms, my back, my flanks/waist & my abdomen. Some fat that was removed from my tummy was then transferred into my buttocks to give it a more perky appearance, this procedure is called a BBL. Recovery was uncomfortable but never painful for me (admittedly I do have a high pain tolerance) so I only took the occasional paracetamol tablet during my 6 weeks of recovery. During that time I wasn’t allowed to sit down, drive a car, or lay on my back plus I had to wear the medical compression garments for 24 hours a day."
Sarah, who was married to Telv Williams on the reality dating show, added that her body and shape and skin firmness look "even better since more time has passed".
"Today I’m feeling fabulous plus I have SO much more confidence! My wardrobe choices are virtually limitless now & I’ve completely ditched my restrictive shapewear which I used to wear daily.
"I’ve certainly had a dramatic change in my body shape. This definitely isn’t a solution for weight loss (as I actually only lost about 5kgs) but rather it’s permanent body sculpting at it’s finest & I’m so glad I did it!"
Many of Sarah's fellow MAFS alumni and friends shared their support in the comments.
Melissa Walsh, who also starred on the show's fifth season, penned: "My beautiful Sarah, I could not be more proud of you. Watching you go through the surgery, and how amazing you were during that recovery period, you have proven what I already knew- that you’re one tough cookie.
"You never complained and maintained your composure the whole time, which is no mean feat when you can’t sit down for six weeks haha. And check out how gorgeous you look. Dr Reza has outdone himself! I know how challenging it must’ve been to put up these before photos but it’s just further proof of how strong you are. I’m so proud to call you my friend. Xxx"
New mum Tracey Jewel wrote: "Wow so proud of you Sarah ❤️🙌 incredible transformation!"
Meanwhile Foxy Jojo, who had her own body transformation after her MAFS experience, exclaimed: "HOLY MOLY u gorgeous thing❤️"
"I sincerely thank you for your absolute openness and honesty with these photos you have shown and for sharing your Journey with us all. It must have taken a lot of strength for you to share them with the world and I thank you so much for that raw honesty. This journey could not have been easy for you especially seeing some of that bruising.
She added: "To me you will always be a 10 out of 10 but after losing weight myself I understand the need to feel absolutely 100% confident within your own skin. Babe the transformation is mine blowing congratulations on achieving your goals."
