What are the risks of LSG surgery?

You may bleed more than expected or develop an infection. Organs near the surgery area may be damaged. During surgery, you may need one large incision instead of several small incisions. A leak may develop along the staple line where it is holding your sleeve closed. This leak can cause a severe infection. You may have nausea, vomiting, or heartburn. You may not lose as much weight as you want or you may gain weight. You may develop a life-threatening blood clot.
