Patients who undergo gastric band surgery typically benefit from a reduced risk of cardiovascular disease within a year of their operation, a study has found.
The procedure is carried out to promote weight loss and reduce obesity-related health risks.
Scientists at health care company Allergan studied 647 patients with an average age of 45 years who underwent gastric band surgery.
Participants all had a body mass index (BMI) in excess of 30 prior to surgery and their BMIs fell from an average of 42.7 to 33.4 after 12 to 15 months.
Patients' risk of developing cardiovascular disease within the next ten years dropped from 10.8 to 7.6 per cent within 12 to 15 months, while their 30-year risk fell from 44.34 to 32.3 per cent.
In addition, they typically showed improvements in their cholesterol levels.
Publishing their findings in the journal Advances in Therapy, the study authors observed that obesity is a "major risk factor" for cardiovascular disease.
They concluded that patients who undergo gastric band surgery "have significant weight loss and reductions in estimated ten to 30-year cardiovascular disease risk within 1 year".
