What is Sleeve Gastrectomy?
Laparoscopic sleeve gastrectomy removes approximately 80% of the stomach, leaving a narrow tube ('sleeve') that limits food intake and reduces hunger hormones. It is the most commonly performed bariatric procedure worldwide and helps patients achieve 60-70% excess weight loss within the first 12-18 months.
How Does Sleeve Gastrectomy Work?
- 1Online consultation with BMI assessment, blood work review, and dietary history evaluation
- 2Pre-operative liquid diet for 2 weeks to shrink the liver and improve surgical access
- 3Five small keyhole incisions are made in the abdomen under general anaesthesia
- 4Approximately 80% of the stomach is removed laparoscopically using a surgical stapler, creating a banana-shaped sleeve
- 5Leak test is performed intra-operatively; you are monitored in hospital for 2-3 nights before transitioning to the hotel
Who is a Good Candidate for Sleeve Gastrectomy?
- Adults with a BMI of 35 or higher, or BMI 30-35 with obesity-related health conditions
- Patients who have tried and failed to achieve lasting weight loss through diet and exercise
- Those with obesity-related conditions such as type 2 diabetes, sleep apnoea, or hypertension
- Individuals committed to lifelong dietary changes and follow-up
- Patients aged 18-65 in acceptable surgical health
Why Choose Sleeve Gastrectomy at MedProper?
Proven Weight Loss
Patients typically lose 60-70% of excess weight within 12-18 months, with significant improvement or resolution of obesity-related diseases.
Reduced Hunger
Removing the fundus of the stomach drastically lowers ghrelin (the hunger hormone), making it easier to eat smaller portions.
Laparoscopic & Minimally Invasive
Five small incisions mean less pain, lower infection risk, and faster recovery compared to open surgery.
All-Inclusive Package
The €2,040 package includes surgery, 2-3 night hospital stay, hotel, transfers, nutrition plan, medications, and 12-month aftercare.
What is the Recovery Timeline?
Day 1-3
Hospital Stay
Clear liquids begin on day 1 after a leak test. You are monitored for pain, hydration, and vitals. Walking starts within hours of surgery.
Day 4-7
Hotel & Liquid Diet
You transition to the hotel on a full-liquid diet (broths, protein shakes). Light walking continues. Most patients fly home on day 5-7.
Week 2-4
Pureed Foods
You gradually progress to pureed meals. Energy levels improve. Desk work can resume after about 2 weeks.
Month 2-3
Soft Solid Foods
Small portions of soft solid foods are introduced. Rapid weight loss is evident. Your nutritionist adjusts your meal plan remotely.
Month 6-12
Full Diet & Major Weight Loss
A balanced, portion-controlled diet is established. Most patients reach 50-70% of excess weight loss by month 12.

Frequently Asked Questions
Most patients lose 60-70% of their excess body weight within 12-18 months. For example, if you are 50 kg overweight, you can expect to lose approximately 30-35 kg.
No. The removed portion of the stomach cannot be reattached. However, the sleeve can be converted to a gastric bypass if additional weight loss is needed in the future.
Yes. Although nutrient absorption is not altered as much as in bypass surgery, the reduced food intake means you will need daily multivitamins, vitamin B12, iron, and calcium supplements.
As with any surgery, risks include bleeding, infection, and blood clots. The procedure-specific risk is a staple-line leak, which occurs in less than 1% of cases and is tested for during surgery.
The €2,040 package includes the surgeon's fee, anaesthesia, 2-3 night hospital stay, post-op medications, nutrition programme, 5-star hotel, VIP airport transfers, and 12-month aftercare with a bariatric dietitian.
