One of the most common questions patients ask before choosing gastric sleeve surgery in Turkey is:
"How much weight will I actually lose after a gastric sleeve?"
The answer depends on several factors, including your starting weight, BMI, eating habits, physical activity and long-term commitment to lifestyle changes. Gastric Sleeve surgery is a powerful weight loss tool, but it is not a miracle cure. The operation helps you eat less, feel full faster and reduce hunger, making it easier to lose weight and maintain healthier habits.
At AYT Clinic Antalya, every patient receives a personalised treatment and nutrition plan to maximise long-term success. Understanding what to expect after surgery helps patients set realistic goals and stay motivated throughout their weight loss journey.
During Sleeve Gastrectomy, approximately 75–80% of the stomach is removed. The remaining stomach becomes much smaller, allowing patients to feel full after eating smaller portions.
The procedure also reduces the production of ghrelin, often called the hunger hormone. As a result, many patients notice they feel less hungry after surgery, making it easier to follow a healthier diet.
Unlike some bariatric procedures, food continues through the normal digestive tract, meaning digestion remains largely unchanged.
Most patients lose 60–70% of their excess body weight within the first 12 to 18 months after surgery.
For example:
These are average results. Individual weight loss varies depending on age, metabolism, activity level and commitment to dietary recommendations.
During the first few weeks, weight loss is usually rapid due to the liquid and soft food stages of the postoperative diet.
Many patients lose between 5–10 kg during the first month, depending on their starting weight.
By three months, patients often notice significant physical changes.
Energy levels improve, mobility increases and clothing sizes begin to decrease.
Many obesity-related conditions, including high blood pressure and sleep apnoea, may also begin to improve.
At six months, patients have usually achieved a substantial portion of their expected weight loss.
Healthy eating habits and regular physical activity become increasingly important for maintaining progress.
One year after surgery, most patients reach their greatest weight loss.
Although weight loss may slow after this point, maintaining healthy lifestyle habits helps preserve long-term results.
Every patient loses weight at a different pace.
The most important factors include:
Patients who actively participate in their recovery and long-term lifestyle changes generally achieve the best outcomes.

No.
Some patients lose weight quickly during the first months, while others experience a slower but steady reduction.
Comparing your progress with other patients is rarely helpful.

Consistency is far more important than rapid weight loss.
