What is Endoscopic Sleeve Gastroplasty (ESG)?

The ESG is a cutting-edge, non-invasive weight loss procedure intended to assist individuals in shedding excess weight and boosting overall wellbeing. It employs an endoscope—a flexible tube fitted with a camera and suturing device—and unlike traditional bariatric surgeries, it does not necessitate incisions or permanent modifications to your digestive anatomy.

Procedure Details of the ESG:

Under general anaesthesia, the ESG procedure, which generally lasts about 60-90 minutes, is carried out. The surgeon introduces the endoscope into your stomach through your mouth. Using the camera for a clear visual, the surgeon positions sutures in the stomach, transforming its shape into a smaller, tubular form. This restricts the amount of food your stomach can accommodate, leading to weight loss.

Typically, this is an outpatient procedure, meaning you can go home the same day. In some cases, based on your personal health and the surgeon’s assessment, a brief overnight hospital stay might be necessary.

Post-procedure Recovery:

The ESG procedure typically allows for a shorter recovery time compared to other weight loss surgeries. You might feel some discomfort, nausea, and possibly experience vomiting in the first few days post-procedure. These symptoms can be well-managed with the right medications. Generally, you can resume normal activities within a week. However, dietary modifications are required—starting with a liquid diet in the first week, then progressing to pureed food, followed by soft food, and finally, a regular diet over several weeks. Regular consultations with a dietician and the medical team are essential to oversee weight loss progress and manage diet changes.

Before & After

Benefits of Undergoing ESG:

The ESG procedure offers several key advantages:

  1. Minimally invasive: The procedure does not involve incisions, reducing risks linked to traditional surgery.
  2. Reversible: ESG is reversible, as no sections of the stomach or intestines are removed.
  3. Rapid recovery: Generally, you can return to your regular activities within a week.
  4. Remarkable weight loss: Most individuals observe substantial and sustained weight loss, enhancing overall health and lifestyle quality.
  5. Improvement in co-morbidities: ESG can contribute to the improvement or even resolution of obesity-related ailments such as type 2 diabetes, sleep apnea, hypertension, among others.

ESG vs. Gastric Sleeve:

Both ESG and Gastric Sleeve aim to decrease the stomach size, but they differ significantly:


The Gastric Sleeve is a surgical procedure that involves the removal of part of the stomach, while the ESG is a minimally invasive procedure with no removal of stomach tissue.


Typically, the recovery time for ESG is quicker than for the Gastric Sleeve.

Risks and Complications

ESG has fewer risks and potential complications compared to the Gastric Sleeve due to its non-surgical nature.


If necessary, ESG can be reversed, which is not an option with the Gastric Sleeve, as a portion of the stomach is permanently removed.

Frequently asked questions about the Endoscopic Sleeve Gastroplasty (ESG)

Endoscopic Sleeve Gastroplasty, also known as ESG, is a weight loss procedure that reduces the size of your stomach without the need for surgery. This is achieved by using an endoscope and sutures, limiting your food intake and helping you lose weight.

The duration of the ESG procedure typically ranges between 60 to 90 minutes, although this may vary depending on individual circumstances.

In most cases, ESG is performed as an outpatient procedure, so you can return home the same day. However, in some instances, a short overnight stay may be required, depending on the patient’s health condition and the surgeon’s evaluation.

The ESG procedure typically has a quicker recovery time than other weight loss surgeries. Most patients can get back to their normal routine within a week. Post-procedure, dietary modifications are required, with a gradual shift from a liquid diet to pureed foods, then soft foods, and eventually, a regular diet over several weeks.

The results can vary, but on average, patients might expect to lose around 15-20% of their total body weight in the first year after the procedure. Long-term weight loss and maintenance largely depend on your commitment to dietary changes and lifestyle modifications.

Like any medical procedure, ESG comes with potential risks. These may include nausea, abdominal pain, and vomiting post-procedure. More serious complications are rare but can include conditions like bleeding, perforation, or infection.

Yes, a significant benefit of the ESG procedure is that it’s potentially reversible. This is unlike other forms of bariatric surgery like gastric sleeve where a part of the stomach is removed permanently. The sutures used in ESG can be removed if necessary.
