Better Sleep Beyond the Scale: Why Weight Loss Alone May Not Stop Snoring

Numerous studies highlight the connection between weight loss and reduced severity of OSA. For instance, research published in the Journal of Clinical Sleep Medicine (PMCID: PMC3021364) indicates that weight loss has been shown to reduce the severity and symptoms of Obstructive Sleep Apnea (OSA), however, the study also notes that this isn’t always the outcome.

This underscores that while weight loss can be a crucial component of managing OSA, it’s not a guaranteed fix. Other factors, such as anatomical and genetic predispositions, can contribute to the condition, making it essential to consider additional treatments.

Contrary to popular belief, not all individuals with OSA are obese. A study published in Sleep Medicine Clinics (DOI: 10.1016/j.jsmc.2023.05.010) found that only 37% of individuals with OSA were obese. However, a majority of individuals with OSA (73%) were still overweight. This distinction is crucial because it highlights that weight is a contributing factor but not the sole determinant of OSA.

The study also suggests that there may be a significant number of non-obese individuals unknowingly suffering from OSA. This is potentially due to biases in screening and referral practices, as healthcare providers often prioritize screening overweight or obese individuals for sleep apnea. The study states, “it is possible that OSA at all levels of severity in non-obese populations is more common in the community compared with patients presenting to sleep clinics.”

While excess weight is a well-known risk factor for OSA, there are numerous other reasons why someone might develop the condition. Anatomical factors, such as a naturally narrow airway, enlarged tonsils, or a deviated nasal septum, can contribute to airway obstruction during sleep. Genetic predispositions may also play a role, as some individuals inherit traits that make them more susceptible to OSA. Additionally, hormonal changes, such as those occurring during pregnancy or menopause, can increase the risk of developing sleep apnea. Lifestyle habits, like excessive alcohol consumption or smoking, can further exacerbate the problem by relaxing throat muscles or causing inflammation in the airway.

A fairly common misconception is that OSA only affects older, overweight men. In reality, sleep apnea does not discriminate by gender, age, or race. Women, children, and individuals of all ethnic backgrounds can and do suffer from OSA. Recognizing this diversity is critical for improving awareness and encouraging broader screening practices.

Although weight loss alone may not always resolve snoring or OSA, it can enhance the effectiveness of other treatments. For example:

• Continuous Positive Airway Pressure (CPAP): Weight loss can make CPAP therapy more effective by reducing airway resistance, and easier tolerated with lowered air pressure.
• Mandibular Advancement Devices (MAD): These oral devices hold the jaw slightly forward during sleep to keep the airway open, and their efficacy can improve when weight loss reduces tissue & inflammation around the airway.
• Surgical Treatments: Procedures to remove excess tissue or reposition structures in the airway can yield better results in individuals who have reduced their weight.

At Daybreak, we offer fully at-home solutions for testing and treating snoring & OSA. Our FDA-cleared, custom-made oral appliances provide a convenient and effective treatment option, especially when combined with lifestyle changes like weight loss. 

While weight loss plays a significant role in managing snoring and OSA, it’s often not the sole solution. Anatomical factors, screening biases, and misconceptions about the condition all contribute to the need for comprehensive care.
