Carl's Success Story

at Emerson's Center for Weight Loss

Suffering from obesity is often challenging because it affects a person’s physical and emotional health.
Emerson’s Center for Weight Loss has a unique approach with patients. With respect and expertise,
staff treat every patient as an individual and work hard to help them meet their goals. The surgeons use
advanced approaches to treat obesity and provide patients with the best possible outcomes for a
healthy life.

Sometimes, years after their initial bariatric surgery, patients may experience weight regain or
complications. These challenges can happen due to the surgery type, how the patient’s body acclimates
to the changes, and nutrition and exercise habits. When this happens, patients often do not know
where to turn for help or realize that new options are available for healthy, long-term success.
Emerson’s Center for Weight Loss is one of the only bariatric surgery programs in New England that
treats patients with complex issues based on prior surgeries.

Emerson’s team is experienced with using modern methods for revisional bariatric procedures — with
great success. Like they did with Carl Campbell (pictured).

Carl, age 55, of Kingston, New Hampshire, called the Emerson Surgical Weight Loss team recently to
say: “Thank you for saving my life.”

In March 2021, he had a duodenal switch procedure at Emerson, performed by bariatric surgeon David
Lautz, MD, FACS, FASMBS, medical director of Emerson’s Center for Weight Loss.

Duodenal switch is a type of weight loss surgery that is more powerful than traditional gastric bypass.
It is appropriate for patients who have never had bariatric surgery as well as patients like Carl, who
need a stronger option than their original gastric bypass surgery.


In 2005, Carl had gastric bypass surgery at a different hospital with another surgeon. Over the years,
he regained nearly 200 pounds.

“When I met him, he was suffering from medical problems, including falling asleep in the middle of the
day due to sleep apnea,” explains Dr. Lautz. After a thorough assessment, Dr. Lautz determined Carl
needed duodenal switch surgery.

“For those who regain a significant amount of weight after a gastric bypass, often the most effective
option is to convert the bypass to a duodenal switch. Conversion entails two operations spaced three
to six months apart. These procedures can be remarkably effective for patients who have no other

“My breathing and sleeping were bad. I am a retired semipro football player with eight children and 10
grandchildren. I own a construction company and was in the midst of our busiest year ever. I needed to
get my life back,” says Carl.


“Scrolling through Facebook one day, I saw a story about how a person’s life improved because of
weight loss surgery at Emerson. I did not even finish reading the story. I picked up the phone and called
Emerson’s Center for Weight Loss. The person who answered really listened to me and talked about
some options. I booked my first appointment to start the revision process during that call.”

Nine months after his duodenal switch surgery, Carl is down 182 pounds. He currently weighs 232,
sleeps well, and lives life to the fullest.

“I am so blessed and thankful. I have lots of energy now and no longer fall asleep in the middle of the day. I get up at 5 a.m. every morning and come home late after seeing customers and managing busy construction sites. On the weekends, I boat, golf, and enjoy life with family and friends.
“People do not recognize me. Last summer, I wore size 54 pants, and today I wear size 34. I do not take any medications except for vitamins. At my last checkup, I hugged Dr. Lautz. It is impossible to explain how grateful I am to the Emerson team for giving me my life back.”
