Similarly, a retrospective cohort study comparing 7,925 obese people who underwent gastric bypass surgery with the same number of obese controls matched by age, gender, and BMI showed that after a mean follow-up of 7.1 years, adjusted mortality for surgical patients was 37.6 per 10,000 person-years, compared with 57.1 per 10,000 for controls, a relative difference of 40%. Additionally, diabetes-specific mortality declined by 92% in the gastric bypass patients (N. Engl. J. Med. 2007;357:753-61).
Following surgery, it is important to ensure that patients have a protein intake of 60-120 g daily, and if they have undergone gastric bypass or duodenal switch procedures their diet should be supplemented with a multivitamin containing folate, thiamine, iron, vitamin B12, calcium, and vitamin D, Dr. Bantle said.
"I would suggest that the earlier the surgery is done, the better. Remission of diabetes is predicted by short duration of diabetes, need for few diabetes medications, and high postprandial C-peptide, so if a patient is considering [bariatric surgery], I typically get a postprandial C-peptide and use that to counsel them about whether or not they’re likely to have remission of diabetes after the procedure," he concluded.
Dr. Bantle reported having no financial disclosures.
