Disadvantages & Risks of Biliopancreatic Diversion Surgery - Obesity Surgery Guide

There are benefits from all types of surgery but there are risks as well. These are as follows:

  • Infection
  • Leakage due to a perforated bowel or stomach. 
  • Bleeding
  • Blood clots (deep vein thrombosis)
  • Pulmonary embolus (risk of blood clots in the lungs)
  • Vitamin/mineral deficiencies.  This includes protein deficiency and ‘night blindness’ due to malabsorption of vitamin A. 
  • Risk of osteoarthritis as a result of problems absorbing calcium and vitamin D – both of which are needed for bone health.
  • More risks during this procedure than for a gastric bypass.
  • There may be changes to body odour
  • Requires a longer stay in hospital.  Four days as compared to two days for other procedures.

Death during or following this surgery is extremely uncommon.  It accounts for 0.5% of cases.
