<p><strong>What is Stomach Reduction Surgery (Sleeve Gastrectomy)?</strong></p>

It is a bariatric weight-loss surgery in which 70–80% of the stomach is removed, leaving a narrow, tube-shaped stomach that looks like a “sleeve.”

Why does it help with weight loss:

  • You feel full very quickly, even after eating small amounts
  • The body receives fewer calories
  • The level of the “hunger hormone” decreases

How much weight is lost and when:

  • During the first year after surgery, patients lose on average about 70% of their excess weight
  • For example, a person weighing 130 kg may lose 35–45 kg within the first year
