“Very recently I was diagnosed with PCOS, Polycystic Ovary Syndrome, a hormone imbalance,” Sasha explained to viewers. Until then, her weight gain had been a mystery, even to herself. “I had no idea what was going on and I didn’t have any way of solving it,” she said.

Sasha admitted that gaining weight in the public eye was not easy. “It was really, really hurtful the way people reacted,” Sasha confessed. “People were staying stuff like: ‘She’s pregnant.’ ‘You’re fat.’ They were angry or mad that I looked like this. It was one of the hardest things I have ever been through.”

Luckily, though, DWTS has helped Sasha get her confidence back. “I’m feeling like me again,” she explained. “Being on the show, I’ve lost over 15 pounds. It’s not an easy road, but being able to focus on getting myself healthy again, and the fact that I’m seeing results, getting better is all I can ask for.”
