  • 3–4 day recovery at Sigulda Hospital
  • EU-certified hospital care since 2009

Methods & Health Benefits of the Surgery

  • Restriction: The stomach is reduced in size, allowing smaller meals and faster fullness.
  • Mild Malabsorption: A section of the intestine is bypassed, lowering calorie absorption.
  • Single Anastomosis: One connection point shortens the surgery and recovery time.
  • Laparoscopic Method: Small incisions for minimal scarring and faster healing.

Key Functions

How Mini Gastric Bypass Works

During the One Anastomosis Gastric Bypass (Mini Bypass), the surgeon creates a small stomach pouch and connects it to the small intestine. This combination of restriction and mild malabsorption supports long-term weight loss with a shorter, simpler procedure.

  • Shorter surgery time – Single anastomosis for reduced complexity
  • 3–4 day in-hospital recovery with full medical supervision
  • Comprehensive aftercare & support included post-surgery
