Risks of Sleeve Gastrectomy - Obesity Surgery Guide


Sleeve gastrectomy is a relatively new procedure which means that any long term risks are as yet unknown.  It is a safe procedure but all types of surgery carry a small amount of risk.

The risks are:

  • Infection.  The wound may become infected.
  • Leakage.  The remaining stomach is stapled but there is the possibility that these staples will pull apart which can cause a leak.  Stomach acids are likely to be leaked through these staples which can then become infected.
  • Blood clots (deep vein thrombosis)
  • Weight gain.  The stomach does stretch over time which means food intake will be increased.  And this increase can result in weight being regained.
  • Marginal ulcers
  • Adverse reaction to anaesthesia (this is very rare)
  • Respiratory problems
  • Pulmonary embolus (blood clots in lungs)

Death from sleeve gastrectomy is very uncommon.  This procedure is usually undertaken by experienced surgeons only and mortality rates are around 0.1%.

Something else you might want to take into account is the fact that this procedure may not be covered by private medical insurance.  It is a new form of weight loss surgery and as any long term benefits are as yet unknown, your insurance provider may not include it in your policy.

If you are thinking of using private health insurance to pay for this surgery check first with your insurer to see if they will provide cover.
