Risks and Complications of Bariatric Surgery

Your Physician Will Help Your Understand The Risks

The decision to have any type of surgical procedure is serious. Bariatric surgery should be considered after you and your physician have explored other alternatives.

As with any surgery, bariatric surgery has risks including bleeding, serious infection, bowel obstruction, cardiac problems, blood clots, and gastrointestinal dysfunction. Our expert team of nurses and physicians takes every step possible to maximize safety and minimize risks for our patients. At the time of your consultation, we will help you understand your personal risks and decide if surgery is right for you.

Complications of bariatric surgery include, but are not limited to:

  • Bleeding from a tear to the liver, spleen, or blood vessels.

  • Bowel obstruction, requiring further surgery.

  • Cardiac problems. Greatest risk in patients who are the most overweight, or who have cardiac disease.

  • Complications due to anesthesia and medications.

  • Deep vein thrombosis. Blood clots in the large leg veins. They become serious when they float up into the blood vessels of the lungs. Prevention methods include wearing compression stockings, taking blood thinners and walking as soon as possible after surgery.

  • Dehiscence or rupture of a wound.

  • Gastrointestinal dysfunction, such as long-term nausea or food intolerance.

  • Hernia. One of the more common complications requiring another operation to fix.

  • Infections of the wounds.

  • Leaks from a break in the staple line between the stomach pouch and small intestine.

  • Marginal ulcers in the pouch.

  • Pulmonary (lung) problems, such as pneumonia or fluid on the lungs. These can often be prevented by getting the patient up and about as soon as possible.

  • Spleen injury or tear. Most in common in patients who have had a previous surgery.*

  • Stenosis or narrowing of the connection between stomach pouch and intestine, which may require a procedure to correct.

  • Hair loss or thinning of hair—this is temporary.

NOTE: If complications occur during laparoscopic surgery, the doctor may switch to open surgery.

Related Risks

  • Not losing "enough" weight. Though most patients lose enough weight to significantly improve their health, some are not happy with the results. This can often be avoided by having realistic expectations prior to surgery.
  • Emotional stress. Bariatric surgery leads to many changes, positive and negative, which taken together can become stressful. However, you can take several steps to prepare yourself mentally for the challenges.

Reduce Your Risks

Of course the staff and surgeons at Strong Health take every possible measure to prevent complications. But there are many things you can do to reduce your risks as well.

  • Don't smoke. Ever.

  • Move around. Get up and walk as soon and as much as possible after surgery. This reduces the risk of blood clots and improves lung function.

  • Long before surgery, start practicing the eating habits that will be necessary after surgery to achieve success: counting calories, reading labels, preparing weekly menus, etc.

  • Exercise. The stronger the heart and lungs, the better the body will tolerate surgery.

  • Practice your new way of eating. Get accustomed to the Gastric Bypass Diet.

  • Attend support group meetings. Learn from others.
