A new research, published in the Archives of Surgery, had shown that people who have undergone so-called bariatric surgery for obesity have a higher death rate than other people of the same age. The cause of death is due to suicide and coronary heart disease, in particular.
Researchers from the University of Pittsburgh studied the data for all Pennsylvania residents who underwent a bariatric operation such as stomach stapling or gastric bypass between 1995 and 2004. They then compared the number of death of these patients with that of those in the general population.
It was found that there were a total of 440 deaths after 16,683 weight loss procedures during the study period. Male gender and advancing age were both associated with the increased death rates.
For all age groups, the death rate was much higher in bariatric surgery patients than in the general population. But for patients between the age of 25 and 34, the difference was particularly pronounced. Their death rates for male and female patients were 13.8 and 5.0 per 1,000 persons per year, respectively. In comparison, the death rates in the general population were 1.3 and 0.6 per 1,000 persons per year.
Coronary heart disease was found to be the most common cause of death. 16 suicides were also found with 10 of them were women. Comparing with the data from the general population, researchers estimated that only 3 suicides deaths would have been expected in this number of people.
The researchers also suggested that a better control of high blood pressure, diabetes, high cholesterol, and smoking, as well as efforts to prevent weight regain by diet and exercise, and psychological support to treat depression and prevent suicide could reduce the excess deaths after bariatric surgery.
