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.
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.
