Risks of gastric sleeve include:

Hemorrhage (bleeding)

Leakages from staple lines resulting in infection

Adverse reactions to anesthesia (sedatives) and/or medication

Formation of blood clots (Deep vein thrombosis in the legs / Pulmonary embolus on the lungs)

Longer-term, possible nutritional deficiency

Marginal ulcer

Narrowing of the stomach wall
