BMI 27+ evaluable · No external wounds · Full hypnotic anesthesia
Endoscopic Sleeve Gastroplasty (ESG) is the world's most advanced non-surgical stomach reduction technology, performed entirely through the mouth — no external incisions, no scars.
The surgery uses the technology developed by Apollo Endosurgery. OverStitch™ Suture System, doctors fold the stomach wall into a "sleeve shape" under endoscopy, making you feel full faster when eating and achieving long-lasting and effective weight management.
The world's most advanced endoscopic suturing technology, developed by Apollo Endosurgery. Enables physicians to precisely suture and fold the gastric wall under endoscopy — delivering results comparable to surgical stomach reduction.
Traditional laparoscopic gastrectomy surgery requires an incision in the abdomen 3-5 holes; ESG is performed entirely through the mouth, without any incision on the abdomen, and the recovery period is short.
According to international clinical research, ESG can reduce an average of 15-20% of body weight 1 year after surgery, and the long-term follow-up effect can be Lasts at least 5 to 10 years, the durability is significantly better than pure drug treatment.
Gastric suturing is not suitable for everyone, and a complete preoperative evaluation is key to ensuring safety and effectiveness. The following are common suitable and unsuitable groups. Detailed evaluation still needs to be confirmed by a doctor.
Pull height and weight, check metabolic comorbidities, and instantly view your ESG Fit Score and recommended treatment path. This result is for reference only, and the final fitness still needs to be confirmed by a doctor in person.
*This assessment is for reference only and is not a medical diagnosis. Actual suitability is subject to physician consultation and complete preoperative examination.
Not eligible for NHI-covered bariatric surgery — ESG is the ideal non-surgical alternative.
Diet, exercise, and medication are ineffective and require structural intervention.
Hopefully, the stomach can be shrunk in the least invasive way and recovery can be quick.
Prediabetes, hypertension, and sleep apnea require accelerated control.
ESG outpatient surgery level, most patients return home on the same day and recover for 1-3 days after surgery. Office workers can return to work 5-7 days after surgery.
Reflux symptoms may be aggravated after suturing, and a complete evaluation is required first.
People taking anticoagulants are at increased risk of bleeding.
A history of surgery such as sleeve gastrectomy and gastric bypass affects the anatomy.
Strict dietary restrictions in the early postoperative period are not suitable for the needs of pregnancy.
Weight loss goals can be achieved non-invasively and do not require ESG.
ESG gastric suturing combines the latest endoscopic suturing technology to achieve the best balance between gastric shrinkage effect and safety.Moderately obese people The preferred minimally invasive weight loss option.
ESG is performed entirely through the mouth, without any incisions or punctures in the abdomen.Dressing, swimming, and fitness are not affected, you don't have to explain the scars on your body to anyone – it's the most noticeable cosmetic difference from laparoscopic gastrectomy surgery.
The entire procedure is performed under full sedation anesthesia. You remain completely unconscious throughout. The Naiss anesthesia team uses precision depth-monitoring equipment to ensure the safest anesthetic state.
Compared with the 2-4 weeks recovery period required for traditional surgical gastric reduction surgery, ESG work interruption time significantly shortened, especially suitable for busy urbanites.
ESG at Naiss Clinic is not a single procedure but the starting point of a complete weight loss program.
Different weight loss methods have their own pros and cons, and understanding the differences can help you discuss with your doctor what option is best for you. The following is the main comparison of each method for reference.

From preoperative assessment to long-term follow-up, Naiss Clinic provides a complete five-step treatment course to ensure safety and effectiveness at each stage.
A complete preoperative evaluation will be conducted by a bariatric specialist, including: BMI/body fat/waist circumference measurement, blood biochemistry (blood sugar, blood lipids, liver and kidney function), electrocardiogram, and gastroscopy to confirm the absence of gastric contraindications. The doctor will confirm whether you are suitable for ESG based on the evaluation results, and discuss postoperative weight loss goals and supporting plans.
at least before surgery No food or water for 8 hours. It is recommended to stop using aspirin and anticoagulant drugs 2 weeks before surgery (need to consult the original prescriber). If you are taking GLP-1 drugs, stop taking them 1 week before surgery. An anesthesiologist performs a preoperative assessment.
After the hypnotic anesthesia takes effect, the doctor will OverStitch™ suturing device A special endoscope is inserted into the stomach through the mouth. Under the guidance of real-time endoscopic images, multi-point sutures are systematically performed on the greater curvature of the stomach, and the gastric wall is folded and fixed to form a sleeve-shaped small stomach. The entire process is recorded with images to ensure stitching quality and uniformity.
ESG is an outpatient surgery, and most patients can go home the same day as the surgery. After the operation, observe in the recovery room until the anesthesia has completely subsided, and you can leave the hospital after confirming that there are no abnormalities. After returning home, recovery takes 1-3 days after surgery. On the first day, you will mainly eat clear liquids, and on the second to third days, you will gradually try soft food.
After discharge from the hospital, eat according to the postoperative diet plan.2 weeks, 1 month, 3 months, 6 months and 1 year after surgery Each return visit is followed up to confirm weight loss trends, suture integrity, and overall health. Naiss Clinic provides a complete post-operative support system, including nutritional consultation, CGM monitoring and medication assistance when necessary.
Postoperative diet is the most critical package for the success of ESG. The basic principle is to divide 4 Gradually recover at each stage, and cooperate with the personalized guidance of the weight loss nutritionist in the hospital.
Many patients undergo ESG within the first 3-6 You will lose weight quickly within a few months and then enter a plateau. The advantage of Naiss Clinic is that we have a complete supporting mechanism to break through the plateau period and maintain long-term effects.
GLP-1 weight loss injection can be added after surgery to accelerate the breakthrough of the plateau period, and the synergistic effect is better than that of single therapy.
Instantly understand the impact of each meal on blood sugar and establish a dietary pattern that is most suitable for your personal metabolism.
In-house dietitian guides you through every stage and plateau — every kilogram backed by a plan.
If you need to upgrade, the plastic surgeon will evaluate the advanced route and provide a complete weight loss roadmap.
ESG is a minimally invasive procedure that requires thorough physician evaluation. Prior to surgery, a comprehensive assessment of personal health, medical history, and metabolic markers is essential. Naiss Clinic's gastroenterologists — trained at National Taiwan University — provide complete bariatric consultations and personalized treatment plans.

ESG genus Outpatient surgery level, most patients can return home on the same day of surgery without hospitalization. Postoperative recovery at home 1-3 days, office work type (sedentary) can be resumed about 5-7 days after surgery; for manual labor or work that requires bending and lifting heavy items, it is recommended to return to work 2-3 weeks after surgery. You may experience mild nausea and upper abdominal distension in the first week after surgery. These are normal reactions and will gradually subside as the stomach adapts to the new volume after suturing. The Naiss Clinic will provide post-operative antiemetics and symptom-relief medications to ensure the recovery process is as comfortable as possible.
According to international clinical research data, the average weight loss after ESG surgery is 15-20%(e.g. 100 A patient weighing 15 kg can expect to lose 15-20 kg in 1 year after surgery. kg). Long-term tracking shows that the effect can be Lasts at least 5 to 10 years, the durability is significantly better than pure drug treatment. Key factors that affect the effect include: whether to strictly follow the postoperative diet plan, whether to cooperate with regular exercise, whether to cooperate with drug assistance (GLP-1), and the frequency of postoperative follow-up.
The following situations need to be informed to the physician, which may not be suitable or require careful evaluation:Severe gastroesophageal reflux (GERD),Barrett's Esophagus (Barrett's esophagus),People with abnormal coagulation function or anticoagulant users, have undergone gastric sleeve resection or gastric bypass surgery, severe mental illness is not under control,Pregnant or planning to become pregnant in the near future,as well as BMI < 27 who. The above are just common examples. A complete assessment of contraindications requires an in-person consultation with a physician.
The surgical procedure is in Deep sedation or general anesthesia You won't have any awareness or feelings while doing it. The anesthesiologists at Naiss Clinic use sophisticated anesthesia depth monitoring equipment to ensure that your surgery is completed under the safest anesthesia. The surgery itself (approx. 45-90 minutes) you won't feel any pain at all. After waking up, some patients will feel mild throat discomfort and a sense of fullness in the upper abdomen, which is completely different from the pain of abdominal wounds caused by traditional surgery, and can usually be effectively controlled with oral analgesics.
You cannot return to your normal diet right away. Your post-operative diet is ESG. The most critical package for success. The basic principle is points 4 stage of gradual recovery: Clear liquid (1-2 weeks) → Full liquid (3-4 weeks) → Soft food (5-8 weeks) → Normal solid food (from week 9 onwards). Many patients are most worried that "the postoperative diet will be difficult to eat." In fact, modern postoperative diet plans are much more flexible than in the past. Our weight loss nutritionists will make personalized recipe suggestions based on your eating habits, taste preferences and lifestyle, so that you can still enjoy eating within the limits.
Can. This is also ESG One of the important advantages - it doesn't burn bridges. Because of ESG If no gastric tissue has been removed, laparoscopic sleeve gastrectomy or gastric bypass may still be considered if further surgical intervention is assessed later (Roux-en-Y Gastric Bypass) and other techniques. This "progressive weight loss route" is a very important psychological comfort for many patients who are afraid of undergoing a major surgery at one time. Naiss Clinic integrates plastic surgery and weight loss clinic expertise to provide a comprehensive escalation pathway.
These two methods are suitable for different groups and have different mechanisms. They are not an either-or relationship, but can be combined strategically.The strongest combination: ESG + GLP-1: Add GLP-1 1-3 months after surgery Medications can maximize the rate of weight loss in the early stages, and after reaching the target weight, gradually reduce the dose or discontinue the medication, while maintaining dietary control by reducing gastric volume. This is currently the most recommended combination strategy by many weight loss doctors in the world, and it is also a complete program that Naiss Clinic can provide.
ESG is currently in Taiwan Health insurance has not yet been included in benefits, is a self-funded project. The market price in Taiwan market is approximately NTD 300,000-400,000(Including anesthesia fees, postoperative outpatient follow-up), each clinic has different quotations due to different equipment, physician qualifications and service content. It is recommended that when evaluating the cost, in addition to the cost of the surgery itself, you should also consider: the number and cost of postoperative follow-up clinics, whether nutritionist consultation is included, whether postoperative emergency contact support is provided, and whether the doctor has rich experience. ESG Surgical experience. If BMI ≥35 or ≥32.5 If combined with high-risk diseases, traditional surgical gastric reduction surgery can be applied for health insurance, and you can ask a doctor for evaluation.
ESG at Naiss Clinic The core difference is that Integrated weight loss medical treatment concept rather than just providing a single surgery. General surgery or gastroenterology clinics usually focus on "surgery execution", and postoperative dietary hygiene education and follow-up are relatively limited. Naiss's model is: Weight loss physicians lead preoperative assessment and postoperative medication management; plastic surgeons provide comprehensive surgical pathway evaluation; registered dietitians deliver long-term post-op dietary support; CGM Monitoring tools accurately optimize postoperative diet, plus matching if necessary Synergistic approach to GLP-1 drugs. To put it simply: other places give you a "reduced stomach", while Nice gives you a "complete weight loss plan", and the reduced stomach is just the starting point of the plan.
