Endoscopic Sleeve Gastroplasty (ESG) is a non-surgical weight loss procedure where an endoscope is inserted through the mouth into the stomach and internal sutures are placed to reduce stomach size. This makes the stomach hold less food, helps patients feel full faster, and leads to gradual weight loss without any external cuts or removal of the stomach. It is typically used for patients with mild to moderate obesity who want a less invasive alternative to bariatric surgery.
What is Endoscopic Sleeve Gastroplasty (ESG)?
Endoscopic Sleeve Gastroplasty (ESG) is a minimally invasive bariatric endoscopic procedure that reduces stomach volume using internal stitching. Unlike traditional surgery, there are no incisions, no stomach removal, and no external scars.
The stomach is reshaped into a smaller tube-like structure, limiting food intake and supporting long-term calorie reduction.
How ESG Works (Step-by-Step)
ESG is performed using a flexible endoscope inserted through the mouth.
Procedure flow:
- Patient is placed under deep sedation or general anesthesia
- Endoscope is guided into the stomach
- A suturing device is attached to the endoscope
- Internal stitches are placed strategically
- The stomach is folded inward and tightened
- Gastric volume is reduced by up to ~60–70%
Result: smaller stomach capacity + earlier satiety + reduced calorie intake
Who is Suitable for ESG?
ESG is generally recommended for:
- BMI around 30–40 (case dependent)
- Patients with failed diet and exercise programs
- Individuals who want a non-surgical weight loss option
- Patients not ready for gastric sleeve surgery
- Mild to moderate obesity cases
Not ideal for:
- Severe or morbid obesity requiring surgical bypass/sleeve
- Patients with complex gastric disorders (requires evaluation)
ESG Results & Weight Loss Expectations
Weight loss outcomes depend heavily on compliance.
Average results:
- 3 months: early visible reduction in weight
- 6 months: steady fat loss phase
- 12 months: significant transformation phase
Typical total body weight loss:
- 15% – 20% average total body weight reduction
Key factor:
ESG only works long-term if combined with dietary discipline and lifestyle change.
ESG vs Gastric Sleeve vs Gastric Balloon
| Feature | ESG | Gastric Sleeve | Gastric Balloon |
|---|---|---|---|
| Type | Endoscopic | Surgery | Non-surgical |
| Incisions | No | Yes | No |
| Stomach removal | No | Partial | No |
| Recovery time | 2–5 days | 1–2 weeks | 1–3 days |
| Weight loss level | Moderate | High | Mild–moderate |
| Reversibility | Partially | No | Yes |
ESG Cost in Malaysia
The cost of ESG in Malaysia typically ranges:
RM20,000 – RM35,000+
Price depends on:
- Specialist experience
- Endoscopy facility fees
- Hospital setting
- Pre-procedure assessments
- Follow-up care package
ESG Recovery Time & Diet Phases
Recovery is relatively fast compared to surgery.
Recovery timeline:
- Day 1–2: mild bloating, nausea possible
- Day 3–5: return to normal daily activities
- Week 1–2: dietary adjustment phase
Diet stages:
- Clear liquid diet
- Full liquid diet
- Soft diet
- Gradual solid food reintroduction
Risks & Side Effects of ESG
ESG is generally safe, but like any medical procedure, it carries risks:
Common (temporary):
- Nausea
- Abdominal discomfort
- Acid reflux
Rare:
- Bleeding
- Infection
- Suture loosening over time
Serious complications are uncommon when performed by trained specialists.
Is ESG Permanent?
ESG is long-lasting but not permanent like surgical procedures.
- Stitches may loosen over time
- Stomach can gradually stretch
- Weight regain is possible without lifestyle control
ESG success depends on long-term behavioral change.
Benefits of ESG
- No surgical cuts or scars
- Faster recovery than surgery
- Lower risk profile
- Preserves stomach anatomy
- Suitable for moderate obesity
- Can be combined with lifestyle therapy
Limitations of ESG
- Less weight loss compared to gastric sleeve
- Requires strict dietary compliance
- Not suitable for very high BMI cases
- Weight regain possible if lifestyle is not maintained
ESG vs Other Weight Loss Options
ESG sits between:
- Diet & exercise (low effectiveness alone)
- Medication therapy (moderate support)
- Bariatric surgery (high effectiveness, invasive)
ESG = middle-ground solution for moderate obesity.
Conclusion
Endoscopic Sleeve Gastroplasty (ESG) is a non-surgical, incision-free weight loss procedure that reduces stomach size using internal sutures. It offers moderate but meaningful weight loss with faster recovery and lower risk compared to traditional bariatric surgery. However, long-term success depends heavily on lifestyle changes and patient compliance.
FAQs
1. What is Endoscopic Sleeve Gastroplasty (ESG)?
ESG is a non-surgical procedure that reduces stomach size using internal stitches placed through an endoscope, helping patients eat less and lose weight.
2. How much weight can I lose with ESG?
Most patients lose about 15%–20% of their total body weight within 6–12 months, depending on diet and lifestyle adherence.
3. Is ESG better than gastric sleeve surgery?
ESG is less invasive with faster recovery, but gastric sleeve usually results in greater and more permanent weight loss.
4. How long does ESG take to recover?
Most patients recover within 3–5 days for normal activity, with full dietary adjustment over 1–2 weeks.
5. Is ESG safe?
Yes, ESG is considered safe when performed by trained specialists. Side effects are usually mild and temporary, while serious complications are rare.
