Diabetes May Return In Some Gastric Bypass Patients.
"Gastric bypass surgery reverses diabetes in many obese patients, but the disease returns in about one-fifth of them within three to five years," according to a study presented Saturday at the Endocrine Society's annual meeting. For the study, "researchers examined the medical records of 72 obese people with type 2 diabetes who had a Roux-en-Y gastric bypass procedure between 2000 and 2007, and had at least three years of follow-up visits."
"Patients with a disease duration of five years or longer had almost a four-fold higher likelihood of diabetes recurrence as compared with patients who had diabetes for a briefer period before surgery,"
"Diabetes duration was the only clinical or demographic factor associated with recurrence," the study found. The moderator of a press briefing in which the study was presented theorized that "one plausible explanation for the diabetes recurrence is greater beta-cell depletion among patients with longer-duration disease."
