Study Overview:
Obesity and Obstructive Sleep Apnea (OSA) are strongly linked. This study aims to understand whether a procedure called Endoscopic Sleeve Gastroplasty (ESG), along with lifestyle changes like healthy eating and regular exercise, can help improve symptoms of OSA in people with obesity.
What is Obstructive Sleep Apnea (OSA)?
OSA is a condition where your breathing repeatedly stops and starts during sleep. This happens when the airway becomes blocked-often due to extra fat around the neck and throat in people with obesity. These breathing interruptions can lead to poor sleep quality, daytime tiredness, mood issues, and long-term health risks like high blood pressure and heart problems.
Why Does Weight Matter?
Obesity is a major cause of OSA. Being overweight can cause:
Narrowing of the airway
More inflammation in the body
Hormonal changes
Difficulty breathing properly during sleep
Losing weight can reduce these problems, ease OSA symptoms, and help improve sleep. Even a moderate amount of weight loss can make a big difference.
How Can People Lose Weight?
Many people try to lose weight through:
Diet changes
Exercise
Behavioural changes like mindful eating
These methods can help, but some people find it hard to lose enough weight or keep it off. That's where medical procedures like ESG can help.
What is ESG (Endoscopic Sleeve Gastroplasty)?
ESG is a non-surgical, minimally invasive weight-loss procedure. It works by reducing the size of your stomach using stitches (done through a tube inserted through your mouth-no cuts or incisions on the body). A smaller stomach means you feel full sooner and eat less.
Benefits of ESG:
Helps you lose weight (up to 20% of total body weight)
Lower risk of complications than traditional surgery
Short recovery time
No hospital stay in most cases
What Does the Research Say So Far?
Some early studies have shown that ESG can help people lose a significant amount of weight and may also improve conditions related to obesity, such as OSA.
One study followed 99 people for a year after ESG. About 30% had OSA at the start. After the procedure, many reported improvement in their OSA symptoms.
Another study compared ESG with a more invasive surgery (laparoscopic sleeve gastrectomy or LSG). While LSG led to more weight loss, both groups showed similar improvements in OSA symptoms.
This shows that ESG may be a good option for improving OSA, but more research is needed to fully understand its benefits.
Why Is This Study Important?
With obesity and OSA becoming more common, it is important to find effective and safe treatments. This study will help us learn:
How much ESG can improve sleep and breathing in people with OSA
Whether combining ESG with lifestyle changes is better than lifestyle changes alone
How ESG impacts other health problems linked to obesity
What We Hope to Learn:
We believe that weight loss from ESG will:
Reduce the severity of OSA
Improve sleep quality
Improve overall health
The results of this study could help guide future treatment options for people with obesity and sleep apnea.
Full description
Obesity increases the risk of Obstructive Sleep Apnea (OSA), a condition where breathing stops during sleep. This study aims to find out whether Endoscopic Sleeve Gastroplasty (ESG) with lifestyle changes (like diet and exercise) improves OSA symptoms better than lifestyle changes alone. ESG is a non-surgical procedure that reduces stomach size to help with weight loss. Early studies show ESG can lead to weight loss and may reduce OSA symptoms, but more research is needed. This study will compare both treatment approaches to see which is more effective in improving sleep and overall health in people with obesity and OSA.
Primary Endpoints:
Change in OSA severity (measured by apnea-hypopnea index, AHI) from baseline at 12 months after study procedure by group.
Secondary Endpoints:
Study procedure and / or device related SAEs for the ESG group only Responders to weight loss (≥ 10% Total Body Weight Loss, TBWL) with reduction in OSA severity (AHI reduction ≥ 50%) at 12 months after study procedure by group Weight loss (TBWL%) at each study visit by group Improvement in sleep quality (assessed using validated sleep questionnaires) from baseline at 12 months after study procedure by group Epworth Sleepiness Scale (ESS) Pittsburgh Sleep Quality Index (PSQI) Change in OSA severity from baseline at 24 months after study procedure for the ESG group Responders to weight loss (≥ 10% Total Body Weight Loss, TBWL) with reduction in OSA severity (AHI reduction ≥ 50%) at 24 months after study procedure for the ESG group
Additional Endpoints:
Adverse event frequency related to the study procedure Responders to weight loss at each study visit by randomization group Change in OSA severity at each study visit by group Improvement in sleep quality from baseline at each study visit by group Changes in metabolic parameters: HbA1c, fasting glucose, lipid profile, and liver profile.
Changes in blood pressure and inflammatory markers (e.g., hs-CRP). Improvement in quality of life (assessed using validated questionnaires) from baseline at each study visit by group SF-36 IWQOL LITE-CT
