Patient-Friendly Explanation

SASI bypass is a newer weight-loss surgery that combines a sleeve gastrectomy with a connection between the stomach and the lower part of the small intestine. It reduces both how much you can eat and how much you absorb, and may help people with severe obesity or type 2 diabetes.

Clinical Definition

Single anastomosis sleeve ileal (SASI) bypass couples a standard sleeve gastrectomy with a loop gastroileostomy approximately 250-300 cm from the ileocaecal valve. It induces restriction plus moderate malabsorption and favourable gut-hormone changes, improving weight loss and glycaemic control with a single anastomosis.

Why It Matters

SASI bypass is an emerging metabolic procedure that may suit patients who need greater weight loss or diabetes control than a sleeve alone. NuLifeCare Singapore can help you understand whether it fits your situation.
