Endoscopic sleeve gastroplasty (ESG) is a modern, minimally invasive procedure for treating obesity. It is performed through the mouth with an endoscope, without any incisions. The surgeon applies sutures to the inner wall of the stomach, reducing gastric volume by approximately 70% and giving it a narrow, banana-like shape. The patient feels full more rapidly, consuming less food and achieving gradual, stable weight loss.
Clinical studies show an average weight loss of up to 25% of total body weight within the first year, when combined with a balanced diet and physical activity. After the procedure a liquid diet is followed for several weeks, gradually progressing to soft and then solid foods. Periodic visits with a nutritionist and doctor (including blood tests and weight monitoring) support the journey.
