"Implantable Device for Sleep Apnea Ideal for Overweight Individuals"
A new study found that an implantable hypoglossal nerve stimulator for obstructive sleep apnea works best for people who are overweight but not severely obese, with a BMI of up to 32. The device, which costs between $50,000 and $100,000, is approved for people with a BMI of up to 40, but the study suggests that for those with a BMI over 32, the device might be unsuccessful up to 75% of the time. The implant was also found to be less successful for people who sleep on their backs. The device, which is an alternative to CPAP, has been implanted in 60,000 people worldwide and is activated at night to stimulate the tongue and keep the airway open. The study highlights the importance of selecting the right candidates for this treatment, especially those who have struggled with CPAP.
