Would Weight-Loss Surgery Benefit Diabetics?

When a person becomes obese, the only option he or she can opt for is to lose weight. This is because obesity could lead to many serious medical conditions including Type-2 diabetes, heart disease, high blood pressure and stroke.

Of course, there are several avenues that can help achieve the weight loss.  First of all, he or she should start off with combining a reduction of processed foods high in saturated fats, sugar, salt and caloric content of the diet with an increase in physical activity.

If this fails, which always does, he or she might have to approach the doctors for other means that include use of drugs to decrease appetite, block fat absorption or reduce stomach volume.

Bariatric surgery might be recommended in cases of severe obesity. 2 effective types of bariatric surgical procedures are gastric bypass and gastric banding that can limit intake of food energy by reducing stomach size. 

The FDA (Food and Drug Administration) has approved gastric banding for people with a BMI (Body Mass Index) between 30 and 35 who have an illness linked to obesity. Each year, more than 113,000 bariatric surgeries are performed in the United States. They have saved countless lives but these procedures do carry risks as with any other surgery. As they are complex surgeries, they sometimes result in serious complications. The complication rate for all types of bariatric surgery is about 7.5 percent, according to the National Institutes of Health.

However, a gastric bypass or other type of weight-loss surgery could actually help diabetics who are moderately obese. This was what researchers from the University of California, Los Angeles, Rand Health, VA Greater Los Angeles Healthcare System, Olive View-University of California, and the Akasha Center for Integrative Medicine wrote in their paper that was published on June 5, 2013 in ‘Journal of the American Medical Association’ (JAMA).

Their analysis was based on a review of evidence supporting the use of bariatric surgery to treat people who are diabetic and who have a BMI of between 30 and 35, considered to be on the low end of the obesity spectrum.

Diabetics with moderate obesity were found to lose more weight and had better glucose control over 2 years if they got such surgery rather than opting for non-surgical treatment like dieting and drugs. The researchers also noted that patients who had a gastric bypass achieved better results (more short term weight loss and better control of blood sugar levels) than those who underwent gastric banding.

But since the findings were arrived from a relatively small number of trials, it is necessary to carry out more studies to include on how patients do after 2 or more years, complication rates and side effects. Until then, it is inappropriate to recommend bariatric surgery over nonsurgical weight-loss treatment to people who are obese.

Weight Loss Could Help Ward Off Diabetes!

Insulin resistance sometimes combined with absolute insulin deficiency cause Type-2 diabetes to develop. Insulin resistance is a condition in which cells cannot use insulin properly. Type-1 and gestational diabetes are the other two main types of diabetes.

Of the many risk factors identified for Type-2 diabetes, obesity, sedentary lifestyle and unhealthy eating habits are somewhat associated with weight gain. High cholesterol, high blood pressure, family history and genetics, and increased age can also raise the likelihood of getting Type-2 diabetes.

A study conducted by researchers from Johns Hopkins University in Baltimore found that Type-2 diabetes could possibly be reversed if obese diabetics go for a weight-loss surgery. Their findings published on August 16, 2010 in the medical journal, ‘Archives of Surgery’ indicated that 75 percent of obese diabetics who had undergone weight-loss surgery (bariatric surgery) could actually stop taking diabetes medications within 6 months of their operation.

Researchers carried out one of the few studies examining how surgery can affect health cost in Type-2 diabetics by analyzing insurance claims data from 2,235 patients who underwent bariatric surgery during a 4-year period.

The results showed that among the diabetic patients who had bariatric surgery, only one quarter were still taking diabetes drugs 6 months later. In fact, the number kept falling: 12 months after the surgery, less than 20 percent of patients were taking medications and 24 months after surgery, only 15 percent were still been prescribed with medications.

It has long been known that diabetes and obesity can rarely be reversed once they are developed. This is definitely good news for obese Type-2 diabetics since the need for chronic medications can be eliminated and the overall medical cost could be reduced too. More importantly, this can greatly reduce the risk of developing heart considering the fact that diabetes is a risk factor for heart disease.

Nevertheless, it seems that bariatric surgery would be the only solution that most of the obese diabetics can opt for in order to substantially reverse both obesity and Type-2 diabetes, at least for the time being until experts can find a successful non-surgical methods.

Think Before Going For Weight Loss Surgery!

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.
