Endoscopic sleeve gastroplasty, often referred to as ESG, is a minimally invasive weight loss procedure. It helps people manage obesity when diet, exercise, and other non-surgical treatments have not been effective. Unlike traditional bariatric surgery, ESG does not involve external cuts or permanent removal of the stomach. Instead, it uses an endoscope inserted through the mouth to reshape the stomach internally.

In Singapore, the demand for less invasive weight management solutions is rising. Many individuals seek procedures like ESG to avoid surgical risks while still achieving long-term results. Understanding how this procedure works, who it is suitable for, and what to expect can help people make informed decisions about their health.

How Endoscopic Sleeve Gastroplasty Works

The Procedure Explained

During ESG, a flexible endoscope equipped with a suturing device is guided through the mouth into the stomach. The specialist places sutures in the stomach wall, reducing its size by about 60 to 70 percent. This results in a sleeve-like shape that limits food intake and slows down digestion, making a person feel full sooner.

Non-Surgical Approach

Since ESG does not require abdominal incisions, it is considered a non-surgical weight loss option. This reduces the risk of complications and typically allows for faster recovery compared to traditional procedures such as gastric bypass or sleeve gastrectomy.

Duration and Anesthesia

The procedure usually takes 60 to 90 minutes. Patients are under general anesthesia, ensuring comfort and safety throughout. Most individuals can return home on the same day or within 24 hours.

Benefits of Endoscopic Sleeve Gastroplasty

Weight Loss Results

Patients undergoing ESG in Singapore can expect gradual and sustainable weight loss. On average, many individuals lose 15 to 20 percent of their body weight within the first year. Combined with lifestyle changes, the results can be long-lasting.

Lower Risk Compared to Surgery

Because ESG does not involve cutting or removing parts of the stomach, the risk of infection, bleeding, or severe complications is much lower than surgical methods. It also preserves the stomach’s natural anatomy.

Faster Recovery Time

Most patients resume normal activities within a few days. The absence of external scars and reduced downtime make ESG appealing to those with busy lifestyles.

Improvement in Health Conditions

Weight loss achieved through ESG often helps improve obesity-related conditions such as type 2 diabetes, high blood pressure, sleep apnea, and joint pain. This makes the procedure more than just a cosmetic solution—it plays an important role in overall health improvement.

Who Can Consider ESG in Singapore

Suitable Candidates

Endoscopic sleeve gastroplasty is typically recommended for individuals with a body mass index (BMI) of 30 or higher. It may also be an option for those who are overweight with related medical conditions. People who have not achieved weight loss through diet, exercise, or medication may benefit from this approach.

Exclusion Criteria

The procedure may not be suitable for those with large hiatal hernias, bleeding disorders, or previous stomach surgeries. Pregnant individuals or those planning pregnancy soon may also be advised against ESG.

Psychological Readiness

Candidates must be mentally prepared to adopt long-term lifestyle changes. The procedure is most effective when combined with healthier eating habits, regular physical activity, and ongoing medical support.

Risks and Considerations

Common Side Effects

Mild side effects such as nausea, abdominal discomfort, and vomiting are common in the first few days after the procedure. These usually improve with medication and time.

Potential Complications

Although rare, risks include internal bleeding, infection, or unintentional stomach perforation. However, compared to surgical bariatric procedures, these complications occur at a much lower rate.

Long-Term Commitment

It is important to remember that ESG is not a quick fix. Patients must commit to long-term dietary adjustments and regular follow-ups to maintain weight loss and prevent regaining weight.

Recovery and Aftercare in Singapore

Hospital Stay and Initial Phase

Most patients are discharged the same day or within 24 hours after ESG. They are usually advised to follow a liquid diet for the first few weeks before gradually transitioning to soft foods and then regular meals.

Follow-Up Support

In Singapore, clinics offering ESG usually provide a structured follow-up program. This often includes nutritional counseling, exercise guidance, and psychological support. Such multidisciplinary care ensures better long-term success.

Returning to Routine

Patients can return to work and normal activities within a few days. Strenuous exercise should be avoided during the initial recovery phase but can be resumed gradually with medical clearance.

Comparing ESG with Other Weight Loss Options

ESG vs Bariatric Surgery

While surgical options like gastric bypass or sleeve gastrectomy may result in more significant weight loss, they carry higher surgical risks and longer recovery times. ESG offers a balance between effectiveness and safety for individuals who prefer a less invasive approach.

ESG vs Lifestyle Modification Alone

Diet and exercise are essential, but for some people, these methods may not result in substantial or sustained weight loss. ESG provides an additional tool to support lifestyle changes and make them more effective.

ESG vs Weight Loss Medications

Weight loss medications can help reduce appetite or absorption of fat. However, they may come with side effects or require long-term use. ESG offers a mechanical solution that reduces stomach capacity without ongoing drug dependency.

Cost and Accessibility in Singapore

Cost Factors

The cost of ESG in Singapore varies depending on hospital fees, specialist expertise, and aftercare services. Factors such as anesthesia, operating room charges, and follow-up programs also influence the total expense.

Insurance Coverage

As ESG is a relatively new weight loss option, insurance coverage may be limited. Patients should consult their insurance providers to check eligibility and possible reimbursement options.

Availability of Specialists

Singapore has a growing number of specialists trained in advanced endoscopic procedures. The increasing availability of ESG ensures that patients have access to safe and modern weight loss options.

Conclusion

Endoscopic sleeve gastroplasty is an effective, minimally invasive weight loss procedure available in Singapore. It offers significant benefits such as reduced stomach size, lower surgical risks, faster recovery, and improved health outcomes. While ESG may not be suitable for everyone, it can be a valuable alternative for individuals struggling with obesity and related conditions. With proper medical guidance and lifestyle adjustments, patients can achieve sustainable results and improved well-being
