TikToker Rachel Tussey Dead at 47

TikToker Rachel Tussey has died after undergoing surgery for a "mommy makeover" ... and things took a turn for the worse.

Rachel's family tells TMZ ... "It is with deep regret and sadness that we share the news of Rachel’s passing. We would like to thank everyone, around the world, who faithfully prayed for Rachel and our entire family throughout this extraordinarily difficult time in our family’s life. The outpouring of support, from our community and beyond, has provided us with so much comfort at a time when it was dearly needed. We ask that our family be given time and space to grieve our unimaginable loss."

Rachel's husband, Jeremy, updated her GoFundMe page, writing ... "We are deeply grateful for the love, prayers, and generous support shown to our family during this incredibly difficult time. Last night, my wife Rachel lost her battle while in hospice care." He added some beautiful words about what she meant to their family ...

He wrote, "Rachel was an amazing wife, mother, and person who touched so many lives. We will carry her memory with us always. From the bottom of our hearts, thank you for standing with our family."

As we previously reported, Rachel, an Ohio mother, had been documenting the process of getting ready for a tummy tuck on social media. Rachel’s husband, Jeremy, announced she had complications from the surgery on March 3.

We spoke with Rachel's doctor -- Dr. Tork -- just after she developed health issues, denying his work played any role ... “I am heartbroken for Rachel Tussey and her family. My thoughts remain with her loved ones during this devastating time. Like them, I am struggling to understand how this could have occurred.”

Today, Dr. Tork told TMZ ... "This is an unimaginable tragedy. I am devastated for Rachel Tussey and her family, and I am sending my deepest condolences and prayers to her loved ones during this incredibly difficult time. My thoughts remain with everyone who loved Rachel. I hope that, in time, the full facts surrounding what happened come to light, bringing clarity and some measure of peace to her family and to everyone affected by this heartbreaking loss."

Rachel was 47.
