Sept. 28, 2009 -- Losing weight may help obese people as well as their partners sleep better by easing sleep apnea symptoms.
A new study confirms that weight loss can significantly improve and potentially eliminate sleep apnea symptoms in obese people.
Researchers found that people with severe sleep apnea who lost the recommended amount of weight were three times more likely to experience a complete remission of sleep apnea symptoms compared with people who didn’t lose weight.
