Gastric bypass

Bariatric surgery - gastric bypass; Roux-en-Y gastric bypass

The risks of gastric bypass surgery include:

• Bleeding
• Infections
• Follow-up surgeries to correct complications, or to remove excess skin
• Gallstones due to significant weight loss in a short amount of time
• Gastritis (inflammation of the lining of the stomach)
• Vomiting from eating more than the stomach pouch can hold
• Iron or vitamin B12 deficiencies (if they occur) can lead to anemia
• Calcium deficiency (if it occurs) can contribute to the development of early osteoporosis or other bone disorders

Follow up surgeries may be less likely if gastric bypass is performed with a laparoscope.

Another common complication from gastric bypass is "dumping syndrome." The symptoms often include:

• Nausea and vomiting
• Diarrhea
• Bloated feeling
• Dizziness
• Sweating

You can lessen these symptoms by following your dietitian's guidelines very carefully, especially during the first two months after surgery.
