Reality TV star Kailyn Lowry of Teen Mom 2 has changed a lot since her humble appearance on 16 and Pregnant. But probably the biggest change of all is her plastic surgery, and the before and after pics prove she’s had a lot done.

In 2016, Kailyn got an entire body makeover, a transformation that was so dramatic, her ex-husband Javi Marroquin said it was one of the causes of their breakup.

From lip injections to her famous Brazilian butt lift, Kailyn has worked hard to get her pre-pregnancy body back — and she’s been surprisingly candid about it, too.

“For years I struggled with eating disorders, and I was extremely self-conscious about my weight,” she revealed in her book, Hustle and Heart. “I’d committed so thoroughly to working out and maintaining a healthy diet, but it was clear there was only so much I could do to change the shape of my body.”

She turned to Michael “Dr. Miami” Salzhauer to get her body back in shape with his popular Brazilian butt lift, which transfers fat from the stomach into the butt.

“My decision to get plastic surgery came down to one simple thing: I’m human,” she wrote in her book. “I care how I look. I knew that being satisfied with my outer appearance would give me the confidence I needed to face the world head on. For me, the things that I wanted to change about my body were nagging little distractions from the deeper missions I wanted to work on.”

She also later got lip fillers, which she regretted.

“Tried to get lip fillers and had a reaction,” she tweeted in 2016. “You should have seen them without lipstick.”

All the modifications she made to her body became a concern for Javi.

“I knew her surgery would change her,” he said in 2016.
