• An internal leakage of digestive juices  into the body cavity
• Wound infection at incision sites
• Hernias - a weakening of the abdominal wall
• Develop gall bladder disease or gall stones – due to weight loss
• Blood clots – may cause a more serious condition called a pulmonary embolism
• Vitamin deficiencies-may be preventable by taking daily vitamin supplements. Periodic lab testing may also be required
• As with any surgical procedure, there is a risk of death
