Rosie O'Donnell Weight Loss: Rosie O'Donnell is justly proud of some extreme weight loss that left her looking good and feeling even better. The comedian lost 50 pounds since 2013, but Rosie is being honest about it. Some of that weight came off because of gastric bypass surgery.

In anew interview with Access Hollywood, Rosie O'Donnell opened up about her health and the procedure that helped her drop 50 pounds.

Rosie told Access Hollywood "I had a thing called the vertical gastric sleeve. It's very different than when you think of bypass surgery. It's newer. They remove two-thirds of your stomach but everything else stays intact, and as a result of that you can't hold as much food. But the very interesting part is that in that other two-thirds are where all the hunger hormones live. There's a technical name. It starts with a g, it sounds like gremlins... that's the biggest surprise, is that you're not hungry, right?"

According to reports O'Donnell underwent weight-loss surgery in 2013 after a series of health issues including a heart attack in 2012.

During am American Heart Association luncheon speech she admitted "I did what many woman do, and I did not take care of myself. And that's why I'm here, to try to get women to know you're worth it, take care of yourself and know the symptoms."

O'Donnell cautioned that the surgery should be used along with a healthy diet and exercise. She said "Now it's a tool, it's not an answer. You can't just get surgery and go 'I'm done' and keep eating the way you did. You have to change the way you eat, you have to exercise."

Since the surgery, Rose said she lost " 44 pounds. Almost 50 pounds. Some days it's 46," she said. "It's a lot slower than it was at the beginning."

So, does the weight loss mean Rosie is feeling sexy? Rosie joked "Sexy? No, I feel better that like my tummy's not in the way, you know, when everybody's naked. But no. I feel maybe less shame a little bit."

Rosie O'Donnell has been busy on social media. O'Donnell posted before and after pictures of her fifty pound weight loss.
