Nutrition, behavior, and weight follow-up

Overview

ESG is not stomach cutting. It uses endoscopic suturing from inside the stomach to reduce capacity and support portion control. Strong outcomes require follow-up for nutrition, habits, and metabolic health.

Who it may suit

ESG may suit selected patients with overweight or obesity who want an option before major surgery. The doctor reviews BMI, related conditions, prior weight-loss attempts, and readiness for follow-up.

How it works

A flexible endoscope is passed through the mouth. Internal sutures narrow the stomach, helping patients feel full sooner without removing stomach tissue.

After the procedure

Diet advances step by step. Hydration, protein intake, medication review, and regular monitoring are part of the long-term plan.

Endoscopic (Non-surgical) Pathway

Minimally invasive, incision-free procedures performed through the mouth.

Endoscopic Sleeve Gastroplasty (ESG) — Stomach Tightening

For patients who have not previously undergone stomach surgery

What is Endoscopic Sleeve Gastroplasty (ESG) Stomach Tightening?

Endoscopic Sleeve Gastroplasty (ESG) is a non-surgical weight loss treatment performed using a thin, flexible tube called an endoscope. The endoscope is gently passed through the mouth, allowing the doctor to see and treat the digestive system without making any cuts on the skin.

Because there are no surgical incisions, these procedures are minimally invasive and typically have a shorter recovery time compared to traditional surgery.

Efficacy
  • Approximately 15–20% total body weight loss within 12 months
  • Up to 20–25% with medical support and structured follow-up
  • Improvements in blood sugar, blood pressure, cholesterol, and joint stress
  • Long-term success depends on lifestyle changes and ongoing care
  • Individual results may vary.
Safety & Potential Complications

ESG is minimally invasive with a low rate of serious complications (around 1% in large studies).

When performed by experienced endoscopic specialists, ESG is considered a safe alternative to surgical weight-loss procedures.

  • Nausea (common, temporary)
  • Abdominal discomfort (common, temporary)
  • Fatigue (common, temporary)
  • Bleeding (rare)
  • Infection (rare)
  • Injury to the stomach (rare)
How Does ESG Work?

ESG works through:

1. Restriction – Internal sutures reduce stomach size by about 60–75%, helping you feel full sooner.

2. Hormonal & Metabolic Effects – Slows gastric emptying and supports improved appetite control.

Because the stomach is not removed, normal digestion is preserved.

  • Mild nausea or discomfort for several days
  • Most patients return to light activities within a few days

FAQ

How is ESG different from sleeve surgery?

ESG sutures the stomach from inside without removing tissue. Sleeve gastrectomy surgically removes part of the stomach and has a different risk and benefit profile.

Can ESG work without lifestyle changes?

ESG should not be viewed as a standalone shortcut. Results depend on diet, habits, follow-up, and metabolic health.

Is hospital stay required?

This depends on the treatment plan and patient health. Preparation and aftercare are discussed before any decision.
