Endoscopic Sleeve Gastroplasty (ESG)
What is ESG?
Endoscopic Sleeve Gastroplasty (ESG) is a minimally invasive, non-surgical weight loss procedure that reduces stomach size using internal sutures placed via an endoscope inserted through the mouth—no external cuts or tissue removal involved. It limits food intake and delays gastric emptying, helping you feel full longer. ESG is reversible, performed under anesthesia, and typically completed within a few hours, with same-day discharge. It’s an ideal option for individuals with a lower BMI seeking long-term weight management with behavioral support.
Who is ESG Recommended For?
ESG is ideal for individuals who:
- Have a BMI of 30–32 or BMI ≥28 with associated co-morbidities (e.g., diabetes, PCOS, hypertension)
- Have not achieved sustained weight loss despite lifestyle interventions
- Are looking for non-surgical options with minimal recovery time and lower risk
Key Benefits of ESG
- Effective Weight Loss : Reduces stomach capacity to limit food intake, supporting weight loss of 10–20 kg over time.
- Minimally Invasive : No external incisions; performed entirely via endoscope for reduced surgical risk.
- Reversible & Adjustable : ESG does not involve permanent changes to anatomy, allowing future modification or reversal if necessary.
- Faster Recovery : Patients typically return to daily activities within a few days, with minimal downtime.
- Scar-Free Procedure : Conducted entirely internally, leaving no visible scars.
- Supervised & Safe : All ESG procedures at the Digestive Health Institute are performed under expert supervision by trained specialists.
Pre- and Post-Procedure Nutrition Protocol
Before ESG :
Patients are placed on a 4 to 5 days liquid diet, prescribed by bariatric nutrition specialists, to optimize the stomach environment for the procedure.
After ESG:
A structured reintroduction of food is followed:
- Week 1-2: liquids and protein-rich fluids
- Week 3-4: Soft and semi-solid foods
- Week 4 onwards: Transition to a customized solid diet plan
This phased approach ensures healing, minimizes complications, and supports sustainable weight loss.
What digestive changes should I expect after ESG?
Common early side effects may include:
- Nausea
- Bloating
- Mild cramping or discomfort
These typically improve within a few days. ESG does not affect nutrient absorption, so vitamin deficiencies are unlikely.
Will I need to take vitamins after ESG?
In most cases, no routine vitamin supplementation is required unless recommended based on individual dietary intake. Unlike surgeries like RYGB or SADI, ESG does not cause malabsorption.
How soon can I return to normal activities after ESG?
Most patients return to light activities or work within 2–3 days.
Heavy lifting and intense exercise should be avoided for about 2–3 weeks.
Always follow your care team’s specific recovery guidelines.
Can I regain weight after ESG?
Yes. Just like any other weight loss procedure, long-term success depends on maintaining healthy habits. Overeating or frequent consumption of high-calorie foods can cause the stomach to stretch and reduce the effectiveness of the procedure.
