Long-term outcomes of bariatric surgery

Bariatric surgical procedures result in greater weight loss than non-surgical treatments and are more effective at inducing initial type II diabetes mellitus remissions in obese patients.

Several clinical trials showed that in the first two years post-surgery, bariatric patients had greater weight loss and type II diabetes mellitus remissions compared against non-surgical treatments. In addition, they also found that larger, long-term (>5 years) observational studies have shown durable weight loss, diabetes, and lipid improvements after bariatric surgery.

According to the researchers, the patients generally felt that their quality of life had improved after the surgery. 95% of patients who had type II diabetes before their surgery were in remission from the disease three years later, and rates of remission for high cholesterol and hypertension were 66 and 74 percent, respectively. Marked improvements in kidney function were also noted.

The benefits are tremendous, with bariatric surgery, patients not only lose a large amount of excess weight, but they also have high remission rates of diabetes, hypertension, sleep apnea, and cholesterol levels. There is a great psychological benefit as well. Patients start to feel much better about themselves and see a dramatic improvement in their energy level.

Bariatric surgery improves fertility and reproductive outcomes in obese women, in a review of the most recent evidence on the safety and efficacy of bariatric surgery as a fertility and reproductive intervention in women of childbearing age, the Scientific Advisory Committee of the RCOG observed that bariatric surgery improves several important markers of fertility. It is also associated with maternal outcomes and pregnancy morbidity that are improved relative to similarly obese patients and comparable to those in the general population. In addition, long-term outcomes for infants born following bariatric procedures also appear improved.

There are still unclear are predictors of outcomes, long-term complications, long-term survival, microvascular and macrovascular events, mental health outcomes, and costs, designing and carrying out such studies would be expensive. More information is needed about the longterm durability of comorbidity control and complications after bariatric procedures and this evidence will most likely come from carefully designed observational studies.
