Could This Weight Loss Surgery Be a Cure for Type 2 Diabetes? - Advanced Laparoscopic Associates

Nearly 10 percent of Americans have a form of diabetes, a condition that affects the ability to regulate blood sugar. Add in the number of people with prediabetes—high blood sugar—and that number jumps to more than 100 million, or about one-third of the U.S. population.

There are two main types of diabetes:

  • Type 1: the immune system mistakenly destroys cells in the pancreas that produce insulin, which brings sugar from the bloodstream into the cells
  • Type 2: through repeated exposure (i.e., a diet high in sugar), the body becomes resistant and eventually immune to the effects of insulin

The outcome of both types of diabetes is that sugar remains in the bloodstream, where it can damage cells and blood vessels. Diabetes is associated with heart disease, kidney disease, liver disease and even vision and hearing problems. In addition, most people with type 2 diabetes are obese.

No Cure for Diabetes… or Is There?

Currently there is no cure for diabetes, but the condition can and does go into remission, which means that blood sugar is normal and there are no signs or symptoms of diabetes. However, because blood sugar fluctuates based on a number of factors, it’s possible the disease will come back.

But what if there really is a cure? Evidence is beginning to mount that a simple, safe, effective weight loss surgery procedure may also be a true cure. You’ve probably even heard of the procedure: gastric bypass.

What Is Gastric Bypass?

Roux-en-Y gastric bypass—or simply gastric bypass—was, until recently, the most popular bariatric surgery procedure in the U.S. (it has since been overtaken by vertical sleeve gastrectomy). It’s been performed since the 1960s, and its benefits for obesity are well-established.

Gastric bypass surgery has two parts. First, the stomach is sectioned off, creating a small pouch that can hold much less food than an unmodified stomach. Then, the intestines are rerouted to connect directly to that pouch, which bypasses part of the intestines. This reduces the number of calories the body absorbs. So, not only do people with gastric bypass eat less food due to a smaller stomach, they absorb fewer calories.

How Does Gastric Bypass Help Diabetes?

Gastric bypass is known to have a strong effect on type 2 diabetes. The American Society for Metabolic and Bariatric Surgery estimates that 80 percent of people who have gastric bypass will achieve complete type 2 diabetes remission. Other estimates are similar.

In fact, bariatric surgery is so promising for diabetes improvement that in 2016, an international group of diabetes authorities voted to include surgery as standard treatment for type 2 diabetes in clinical guidelines.

“This change is supported by documented clinical efficacy and by the evidence of an important role of the gut in metabolic regulation, which makes it an appropriate target for anti-diabetes interventions,” wrote Dr. Francesco Rubino, one of the authors of the consensus statement on clinical guidelines.

Dr. Rubino, a bariatric surgeon who practices in the U.K., was featured in a fascinating 6-minute video by The Economist, which you can view below.

In the video, Dr. Rubino stated that he believes that the section of the intestines that is bypassed in a gastric bypass procedure figure heavily into the development of diabetes. Bypassing this section of the intestines can change a large number of factors independent of weight loss, such as:

  • Bile metabolism
  • Glucose metabolism
  • Hormones
  • Intestinal flora (bacteria, etc.)

Dr. Rubino and others believe these changes can combine to permanently send diabetes into remission.

Who Is a Candidate?

The selection criteria for bariatric surgery to treat obesity are clear and simple. People who want weight loss surgery must have either:

  • A body mass index (BMI) of 40 or greater
  • A BMI of 35 or greater and co-morbid conditions related to obesity, such as diabetes, heart disease or obstructive sleep apnea

The 2015 guidelines (published in 2016) for surgery to treat diabetes are more complicated. In addition to BMI, bariatric surgeons must also take into consideration:

  • Heart disease risk
  • How long the person has had diabetes
  • How well the diabetes is controlled

If you are considering treatment for diabetes, request an appointment at Advanced Laparoscopic Associates.
