Sneak Peek - Tonight's MY 600-LB LIFE: WHERE ARE THEY NOW? on TLC

Tonight at 9/8c on TLC's MY 600-LB LIFE: WHERE ARE THEY NOW?, Bettie Jo battles depression and a cancer diagnosis when she finds out she's pregnant. Susan suffers from a major setback after surgery for her excess skin, which has been thwarting her hopes to conquer her obesity. Get a sneak peek HERE!

Each sixty minute episode of the series tells the powerful story of one morbidly obese individual - many who are home bound, relying on care just to live day to day - as they make the courageous decision to undergo a dangerous gastric bypass surgery in an effort to save their lives and change their world forever. Their motivations for making the drastic change vary - some do it for their loved ones, others to be productive members of society, but all of them have one thing in common - they want to be free from a life trapped in a body.

My 600-lb Life documents the life-saving, but traumatic experience of surgery, the ups and downs of struggling with addiction and dependence, the transformation from being completely dependent to gaining a sense of self worth and the inevitable impact - positive and negative- that change has on close personal relationships. High-risk surgery, addiction, dependency, fear, pain, helplessness, victory, pride - this story is as much about heart as it is about weight loss.
