"The Doctors" begin their sixth season this week, with tomorrow's (Sept. 11) installment showcasing Chaz Bono — who just unveiled his jaw-dropping 75-pound weight loss. He talks about that journey in the recently taped program, while, if all went according to plan, by the time you read this he will have gone under the knife of "The Doctors" plastic surgeon, Dr. Andrew Ordon.

The surgery is on both Chaz' face and body, Dr. Ordon tells us. But he won't divulge any further details. (Look for an unveiling in 4-6 weeks.)

On the show, "he talks about having plastic surgery, and he's finally going to have some plastic surgery, let me just put it that way," says the Dr. Ordon.

As far as Chaz' weight loss, he says, "He did have one of the newer approved diet pills that helped him along. It wasn't earth-shattering, but it really did help him through the tough times." Outside of that, "He really did do it on his own, the good old-fashioned way: diet and exercise. It's interesting that Chaz breaks down the numbers as 90 percent diet to 10 percent exercise. The dietary is so important, just making certain changes."

Chaz, of course, has a unique background — as a transgendered leader in the LBGT community who is also the child of pop music/TV icons Sonny and Cher, not to mention being a veteran of "Dancing With the Stars." One has to wonder how gender reassignment might impact a patient's weight. Also, whether feeling happy about becoming male helped Chaz lose weight.

"You have the extensive hormonal change and shift of adding male hormones and subtracting female hormones, so that all came into play," says Dr. Ordon. And, "No doubt about it, there had to be an emotional component to it that we can only imagine."

He says that Chaz "made up his mind: 'I'm going to get myself in shape, I'm going to get myself looking good," and then was not to be deterred.

No starvation diet was involved? "No, no, no, no. He did it over a nine-month period. He did it gradually with the help of a dietician and a trainer and an endocrinologist watching out to make sure he was doing everything the right way. It's pretty incredible — not only the weight loss, but the improvement in his cholesterol, his blood pressure, his blood glucose. In all of those things, anybody would be proud to have the numbers that he has now."

Dr. Ordon feels that whether or not viewers relate to Chaz, "He's interesting as a person, regardless of his gender change. Some people may find that a little out-there, but they'll see he's very, very positive. He clearly made positive changes, getting his life together and getting it together physically as well."

The "The Doctors" cohost reports that this year's shows "start off with a real bang."

"Each day has seeds of some health news. Tuesday is Embarrassing Questions Day, questions you're too embarrassed to ask your doctor. Wednesday is Hollywood Health." Fridays focus more on news of the day, "which is kind of nice. Most news stories do have a health element, whether you're talking about chemical warfare in Syria or back-to-school immunizations. You can take any news item and find the health aspect to keep it fresh."

In addition to his practice and his TV show, Dr. Ordon's many activities include serving as an assistant professor at the Dartmouth School of Medicine at the University of Connecticut and frequent trips to impoverished lands where he performs surgeries pro bono with Smile Train or as a founding member of the Surgical Friends Foundation.

"This summer, my big trip was to Jordan with a group called the Children of War Foundation with the Division of Plastic Surgery at USC and Children's Hospital of Los Angeles. We did 51 operations on children. There were a couple of Syrian refugees. You know, everything that comes out of the Middle East is negative; it's nice that in Jordan we did a real feel-positive story. This is a country that sits in the middle of a lot of hot spots. We went in there trying to do some good and we did. And we met the queen of Jordan, went to the Dead Sea and had a mud facial." The trip, which took place in June, was recorded, and Dr. Ordon says it will find its way to "The Doctors" as a special segment.

As for how he manages so many activities, he says, "It's all good planning. You have to learn to say no to certain things, to prioritize."

He also keeps up with his daughter and son, who are both medical students. "One is at USC and one is at UCLA. We're going to go to the USC-UCLA football game for sure," he says with a laugh, referring to the crosstown archrivals. "Ours is what you call a house divided."

As for whether either of his young medicos expects to follow his path into plastic surgery, Dr. Ordon says his daughter, the UCLA student, just might. "She went with me on a trip to India for Smile Train and she did still photography of the cleft lips and palates, and she really enjoyed it and she has a real interest in it. I wouldn't be surprised if she went into it."
