Consolidated procedure
One of the most frequently performed surgeries
Gastric sleeve
The gastric sleeve (sleeve gastrectomy) it is a laparoscopic surgery in which it is permanently removed ~75–85% of the stomach, leaving a reservoir narrower and tube-shaped. This helps to eat less, reduce appetite and improvement glucose control through hormonal changes, without intestinal bypass.
Health benefits
Reduce stomach capacity
Promotes significant and lasting weight loss
It allows you to eat less and feel full
Contributes to better metabolic health
When is a gastric sleeve recommended?
The gastric sleeve is indicated for patients with obesity who are looking to achieve lasting weight loss and improve metabolic health.
BMI ≥ 40
With or without associated metabolic comorbidities
BMI ≥ 35
With comorbidities such as type 2 diabetes, hypertension, dyslipidaemia, MASLD (fatty liver) or severe osteoarthritis
BMI ≥ 30
with type 2 diabetes or uncontrolled high blood pressure despite optimal medical treatment
Bypass surgery
Transplant (liver, kidney or heart) or a complex abdominal wall reconstruction
Every case is unique. A personal assessment will allow us to define the most appropriate treatment for you.
Gastric sleeve: evidence and efficacy
Gastric sleeve surgery is backed by clinical evidence: it achieves lasting weight loss, improves metabolic health and reduces comorbidities, with a positive impact on quality of life.
Backed by clinical evidence
Type 2 diabetes
It improves glycaemic control, but long-term remission is usually lower than with gastric bypass
OSEBERG RCTLancet Diabetes Endocrinol, 2025
Weight loss
Clinically significant and sustained weight loss, superior to intensive medical treatment
STAMPEDE RCTNEJM, 2017
Blood pressure
Improve control and reduce medication use, remission is usually greater with gastric bypass
The SLEEVEPASS RCTJAMA, 2024
Liver health (MASH)
Higher probability of histological resolution without worsening fibrosis vs lifestyle alone
BRAVES RCTLancet, 2023
Dyslipidaemia
It improves triglycerides and HDL, and the decrease in LDL cholesterol is usually greater with gastric bypass
OSEBERG RCTLancet Diabetes Endocrinol, 2025
GORD (reflux)
It increases the risk of onset or worsening; if reflux is significant, gastric bypass is preferred.
SM-BOSS RCTJAMA, 2018
Sleep Apnoea
Improvement or remission is frequent, and is similar in the long term compared to gastric bypass
SLEEVEPASS – SM-BOSS RCTBritish Journal of Surgery, 2020
Nutritional security
Fewer late major complications than with bypass in long-term trials
SLEEVEPASS RCTJAMA, 2018
The gastric sleeve is one of the most thoroughly researched bariatric procedures, backed by high-quality clinical trials and long-term scientific evidence
