Weight Gain and Sleep Apnea: How 2 Patients Beat the Vicious Cycle

… Just as apnea contributes to weight gain
On top of this, people who don't sleep well are at a higher risk of becoming obese. In 2004 a Stanford University and University of Wisconsin study found that sleep-deprived people had higher levels of a hormone that triggers appetite and lower levels of a hormone that suppresses it.

Overweight sleep apnea patients usually know that the extra pounds they carry are contributing to their problem, but with barely enough energy to stay awake even during simple conversation, exercise can seem like a foreign concept.

Solving one problem often improves the other
Matt Hanover, 44, has struggled with both weight and sleep problems since adolescence. "I spent every day feeling like I'd been hit by a truck," says the digital media producer in Santa Monica, Calif. "I was too tired to walk up a flight of stairs or around the block."

Once he was diagnosed with sleep apnea and began using an oral breathing device to keep his airway open at night, though, he found that daily exercise wasn't so daunting anymore. "Now that I have more energy, it's easier to be more active," he says. "I've lost 20 pounds since I started my treatment, and hope to lose even more."

Yanis also tried traditional sleep apnea treatments, including an oral breathing device and a continuous positive airway pressure (CPAP) machine, but couldn't get used to wearing either one all night long. But when self-esteem and health worries motivated him to start lifting weights and biking—and he lost more than 50 pounds over the next three years—his symptoms gradually decreased.

His wife moved back into the bedroom, and with his doctor's guidance, Yanis was able to wean himself off his CPAP machine altogether. Now he only occasionally experiences mild apneas and tries to prevent them with lifestyle adjustments, like sleeping on his side to keep his airway open.

Yanis knows that weight loss changed his sleeping patterns and his life. "Now I feel great, especially after a workout," he says. "Whenever I pick up my 30-pound daughter, it amazes me that I was walking around with much more extra weight than that all the time."

Weight loss can help anyone who is overweight, regardless of age or severity of symptoms, reduce the frequency of their sleep breathing disorders, says Dr. Kimmelman.

If you're overweight and have sleep apnea, it's important to approach the two issues together. Losing weight isn't easy—especially if you've never dieted or exercised. But with the help of your doctor, small changes can yield big results.
