Weight Loss Surgery Helps Diabetes And Heart Problems In Ohio

Gastric bypass surgery not only helps obese people lose weight, but it may also help patients’ hearts return to a healthier state and shape, according to a new study in the Feb. 8 issue of the Journal of the American College of Cardiology. This can prove to be good news for individuals in Ohio, where 28.8% of the population is obese according to 2009 data.

Researchers followed more than 400 morbidly obese people who underwent the surgery and 300 obese people who did not. Those who underwent gastric bypass had an average BMI of 48 at the time of surgery (over 40 is considered morbidly obese). Within two years of surgery, the patients had lost an average of 100 pounds and managed to get their BMI down to an average 32 (over 30 is still considered obese).

The surgery recipients also had smaller waists, reduced blood pressure, lower cholesterol levels and less insulin resistance, a sign of prediabetes. Researchers found another key benefit: following surgery, the shape and function of patients’ hearts measurably improved.

“We know obese people get cardiovascular disease more often than non-obese people,” Dr. Sheldon Litwin, chief cardiologist at the Medical College of Georgia and the study’s lead author. “One of the questions out there is: Is it reversible if they lose weight? The answer is yes.”

The connection between obesity and heart disease isn’t fully understood, but obese people often show signs of structural changes to the heart, including excess heart muscle mass in the left ventricle and enlargement of the right ventricular cavity. Both are linked to heart failure and other problems. After surgery, however, examinations of the patients’ hearts showed structural “remodeling,” including reductions in the left ventricular muscle mass and in the right ventricular cavity area.

Although bariatric surgery can lead to profound weight loss and significant improvements in associated illnesses such as diabetes, heart disease, sleep apnea and others, it is still a relatively uncommon procedure. Each year, about 220,000 Americans or about 0.25% of obese Americans undergo weight loss surgery of some kind. SABUNG AYAM
