Tammy Slaton reaches a much-anticipated milestone in her weight-loss journey in the upcoming episode of “1000-lb Sisters.”

In TODAY.com’s exclusive clip of the moment, the reality star visits her doctor, Dr. Eric Smith, to find out if she’s been approved for skin removal surgery.

Since 2020, the TLC series has been following the reality star and her sister, Amy Slaton, as they have worked to lose weight together. The show has chronicled the highs and lows of their journey, including surgeries and setbacks.

The clip begins with Slaton sitting in Smith’s office as he reveals whether she can undergo surgery to remove her excess skin.

“You’ve shown me that you can focus on your nutrition, and because of that, I’m giving you the green light to go back to Pittsburgh and get you scheduled to have your skin removed,” he says.

Upon hearing the news, Slaton smiles, laughs joyfully and thanks her doctor.

Smith goes on to explain that he’s already spoken with her surgeon, who is “on the same page as me.”

“He’s comfortable proceeding with your skin removal surgery, so let’s get it done,” he adds.

In a confessional interview, Slaton reflects on the exciting moment.

“‘You’re approved.’ What? You gave me all that big spiel about not having enough protein, but yet, you were going to let me go up there. OK, cool, thanks,” she quips.

Back in the doctor’s office, Smith asks Slaton how the news makes her feel.

“Relieved,” she replies.

“Relieved? Good,” he says. “I mean, Tammy, you’ve put the work in.”

In his own confessional interview, Smith says he’s “super excited” for his patient.

“I know this is something that she’s wanted for a really long time,” he explains. “It’s not the end of her journey by any means. But it’s kind of that final thing of a reward that I’ve done all this hard work and now I can have this battle scar removed from me.”

While talking with Slaton, Smith suggests that they play a joke on her brother, Chris Combs, who is sitting in the waiting room.

“Do you think they think you’re going to get the green light?” he asks.

“They don’t know,” she replies.

“Can you fake cry?” he asks.

“I could try,” she says.

“Maybe you scream at me,” he teases.

In a confessional interview, Slaton reflects on Smith’s suggestion, saying, “Not too many people know this about Dr. Smith, but he likes telling jokes and he’s a trickster.”

The doctor then steps out into the waiting room and addresses Slaton’s family, saying, “Hey, guys, take it easy on her. She’s really upset. OK? She’s really bummed out. Just take it easy on her, OK?

“I wasn’t planning on saying nothing,” Combs replies.

Slaton seems to have abandoned the joke because she then walks out with a smile on her face and says, “I got approved.”

The reality star then teases her relatives and says, “Well, God dang. Where’s the excitement?”

“I don’t know what the hell’s going on. Dr. Smith’s saying one thing, Tammy’s saying another, and neither one of them got a d— poker face that I’d bank on,” Combs says in a confessional interview.

Smith has been one of Slaton’s biggest supporters throughout her weight-loss journey. Before the latest season of “1000-lb Sisters” premiered, he took to Instagram to congratulate the reality star on her 500-pound weight loss and shared a video to show her body transformation.

In recent months, Slaton has shared several of her weight loss tips on Instagram, explaining that she prioritized protein and hydration. She’s also highlighted the importance of finding a community to support you.

“Weight loss isn’t just a physical battle. It’s a mental one, too,” she said in one recent video. “Having the right support makes all the difference.”
