What Are the Dangers of Bariatric Surgery?

Bariatric surgery, whether through gastric bypass or a lap band, can be potentially life-changing for those unable to lose weight any other way. However, there are some potential dangers associated with any type of weight loss surgery that patients should consider before making a final decision, according to the Mayo Clinic.

  1. Death

    • Any surgery requiring anesthesia carries a minimal but still existing risk of death. Age, medical problems such as sleep apnea, and general health issues can slightly increase the death risk.

    Blood Clots

    • Potentially fatal blood clots can occur after bariatric surgery. They are especially more likely to happen in significantly overweight individuals.

    Leakage

    • Leakage of the stomach staple line required in bariatric surgeries is another possible danger. Most cases can be treated with antibiotics, but others may require emergency surgery.

    Pneumonia

    • Obese patients have more weight and pressure around their chests, which can cause pneumonia after a bariatric surgery.

    Dumping Syndrome

    • Some post-weight loss surgery patients experience a condition known as dumping syndrome. When food passes too quickly to the small intestine, nausea, vomiting, dizziness, sweating and diarrhea can result.
