Sleep apnea and your weight

Sleep apnea is associated with various side effects. The most visible consequence of untreated sleep apnea is weight gain and obesity.1

Obesity is also the primary cause behind sleep apnea in adults. Approximately 40% of people who are medically defined as overweight have sleep apnea while 77% of patients who are morbidly obese have sleep apnea.2 Indeed, being overweight may predispose a patient to sleep apnea. Large, thick necks can increase risk of sleep apnea, as can extra weight around the mid-section of the body.

Obesity and sleep apnea also lead to other potential health risks such as diabetes and cardiovascular disease.

If you’re feeling tired and lack motivation to exercise, you might have a hard time reversing weight gain. Getting treatment for your sleep apnea not only boosts your energy, but also helps you live, breathe and get your life back. Talk to your doctor about getting tailored treatment from ResMed.
