Gastric Bypass Surgery > Complications of Gastric By-pass Surgery

Laparoscopic Roux-en-Y gastric bypass is a major elective surgical procedure. The risks are as follows:

  • Mortality (1-2% of patients), mainly due to pulmonary embolism or gastrointestinal leak
  • Wound infections
  • Gastrojejunal stomal stricture
  • Marginal ulcers
  • Internal hernia
  • Roux limb ischemia
  • Blow-out of the stomach remnant
  • Long-term micronutrient deficiencies (eg, vitamin B12, folate, iron)

You should always discuss with your doctor about the risks of surgery. For a consultation please contact Dr Clement Tsang's offices listed on the right side of the page.
