Obstructive sleep apnea (OSA) is not just a source of loud snoring, it is a medical condition characterised by upper airway obstruction during sleep, leading to reduced oxygenation and frequent arousals.
This common chronic illness affects approximately one of fifth of men and 17 per cent of women, making it a widespread health concern with serious implications.
Traditionally, obesity has been considered a primary risk factor for OSA, given its role in physically restricting the airway. Previous research marks the link between body fat and increased OSA risk, highlighting that a rise in Body Mass Index (BMI) or changes in body fat distribution, such as an increase in the waist-to-hip ratio, significantly heighten the severity of OSA.
However, a recent study published in the Laryngoscope highlights the potential impact of laryngopharyngeal reflux (LPR) on sleep apnea among non-obese individuals.
The study examined 105 adults diagnosed with OSA who were not obese, to focus on factors other than weight that could contribute to their condition. These participants underwent drug-induced sleep endoscopy, which revealed insightful details about how their airways behaved during sleep.
Nearly half of these individuals showed signs of LPR, a condition where stomach acid backs up into the throat, leading to irritation and potential airway obstruction.
One of the most significant findings was the strong association between LPR and airway obstruction at the tongue base. Patients with more severe lingual tonsil hypertrophy, where the tonsils at the back of the tongue are enlarged, frequently experienced more severe obstructions.
Why this matters
These results are interesting for several reasons. They highlight that LPR could be a key factor in the severity and management of sleep apnea, especially in individuals who are not obese.
This shifts some of the focus away from weight management alone and towards a broader view of what contributes to sleep apnea. It also underlines the importance of diagnosing and treating LPR to potentially mitigate its effects on sleep apnea.
Early diagnosis of reflux
Understanding the connection between LPR and sleep apnea touches on the importance of early diagnosis and management of these conditions.
Tools like Peptest, which detects stomach enzymes in saliva that are indicative of reflux, can play a key role in this process. By identifying LPR early, individuals can receive targeted treatments that may alleviate both their reflux and sleep apnea symptoms.
Peptest detects pepsin — the stomach enzyme that marks reflux — in a saliva sample. Collected at home, analysed in our UK laboratory, results back within 48 hours.
