Weight-Loss Surgery is Also Helpful to Diabetes

Brief: The latest release of the two scientific research results show that usually the bypass surgery that been operated for obese patients to loss weight that can also improve their symptoms of diatbetes signigicantly, and it can even reversed the effect of the diesease. Now researchers are studing whether this surgery is also effective to those non-obesity diabetic patients.

Cristina Iaboni, a diabetic, underwent gastric bypass surgery at New York-Presbyterian/Weill Cornell in the fall of 2009 as part of a study. After losing 50 pounds, her blood sugar was nearly normal. She is pictured here in June 2010.

We've been hearing about health care law. Now, simply health care. Two studies released today address options for diabetics. They have found that surgical procedures commonly used to help obese people lose weight can also dramatically improve or even reverse diabetes.

That may offer an alternative treatment for diabetics, as NPR's Rob Stein explains.

Diabetes is one of the nation's biggest health problems and the disease is often caused by obesity. Diabetic Tim Ferree of Macedonia, Ohio, struggled with his weight for years. He knew his out-of-control blood sugar would eventually cause serious problems.

You're looking at, you know, losing your vision, losing your feet, having problems with your kidneys, going blind, you know, heart disease, strokes.

So when Ferree heard about an operation that might help with his weight and his diabetes, he volunteered to get it.

With a brand new baby in the house, that's really what prompted me to take a very aggressive course towards treating the diabetes.

Surgeons have been operating on obese people for years, making their stomachs smaller and rearranging their digestive systems. And doctors realized that patients who got the operations often had their diabetes get much better. Sometimes it even went away completely. But they didn't have good research that proved surgery was really effective.

What's been lacking is a head-to-head comparison of surgery versus some of the newer anti-diabetic drugs.

That's Philip R. Schauer of the Cleveland Clinic. He led one of the studies released today. The results showed that patients who got the operations were much more likely to have their blood sugar go down. Many were able to stop taking any diabetes drugs altogether.

Just the fact we were able to see this many people achieve normal blood sugar without medications is somewhat astonishing. In a sense, we're reversing the disease.

After the surgery, patients would sometimes get better within hours or days. And when that happens, its clear there's something more going on than just the effects of getting thinner. One theory is that re-arranging the digestive system affects important hormones.

There appears to be an increased production of special hormones from the intestinal tract. And these hormones are know to directly stimulate the pancreas to make more insulin.

And insulin controls blood sugar levels. This research raises an important question: Should diabetics start getting this operation more often? It's called bariatric surgery. Paul Zimmet of the International Diabetes Federation thinks they should.

Diabetes coupled with obesity is probably the largest epidemic in human history. At the moment, bariatric surgery is being seen as a last resort. And it should be offered earlier in management.

But others aren't so sure. The new studies only followed about 200 patients. And while the operations appear to be pretty safe, there can be complications. And the complications can be serious.

Vivian Fonseca, a  top scientist at the American Diabetes Association, said: I think we need longer-term follow-up than what was done in these studies, to make sure that you're not trading one problem for another.

For his part, Tim Ferree is thankful. He's 60 pounds lighter. He's off all his drugs - not only for his diabetes, but also for blood pressure and cholesterol.

I'm not staring down the barrel of being diabetic. I'm not looking at a future of potentially having to give myself several insulin shots every day. I'm not potentially looking at, you know, losing a foot or losing my eyesight or having a stroke. That's a great relief, I think, for anyone.

Researchers are now testing whether the surgery works on diabetics who aren't even obese - people with BMIs as low as 26. And doctors and patients are waiting to see if insurance companies will pay for the operations just to treat diabetes.
