Gastric Bypass Surgery Better Than They Thought

Obesity comes with so many risk factors, one being heart problems. There is a connection between obesity and cardiovascular disease, but it’s not fully understood. Obese people tend to show signs of structural change to the heart. They can have the right ventricle become enlarged and excess heart muscle mass in the left ventricle. Both of these conditions are linked to heart failure.

Gastric bypass surgery seems to be helping obese people loose weight and getting their heart back to it’s normal size and shape.

A study was just published in the “Journal of American College of Cardiology.” The researchers followed over 400 obese people who had the gastric bypass surgery. The surgery is designed to reduce the size of the stomach making the individual feel fuller faster.

The first group was compared to a second group of about 300 obese people that did not have the surgery.

After 2 years the average body mass index (BMI) fell from an average 48 to about 32, with the average weight loss being about 100 pounds.

Those that lost the weight, had smaller waistlines, lowered their blood pressure, heart rate and also showed reductions in the heart mass. The heart was indicating that it was less stressed. It was no longer working as hard to pump blood through the body. The heart then began to return back to it’s normal shape.

When people do lose weight it does help them get their heart back to a health heart. Gastric bypass is not without it’s risks, but with studies like this, showing improvements like these, researchers are hoping insurance will start paying for more. Currently only about 1% of obese people have the surgery.

The researchers are going to continue to follow these participants for another 2 years to see if they can keep the weight off, plus see if they can improve their health, and have less heart trouble in the long term.
