A study reveals that weight loss surgery (bariatric surgery) may reduce the risk of heart failure, hypertension, and premature death. The study was based on data from primary care in the United Kingdom.
The finding of the study is published in the British Journal of Surgery.
Clinical studies have revealed that bariatric surgery helps in reducing risk cardiovascular disease but the studies based on real-world-data are very limited. In this population-based cohort study, the researcher analyzed 5,170 obese patients who have gone through bariatric surgery and 9,995 obese patients who just had routine care.
Obesity is one of the chronic diseases which are associated with various comorbidities and other complications. It is defined as having a body mass index of 30 or above. Around 70 million adults in America are obese. 99 billion people are obese.
The data from the recent Behavioral Risk Factor Surveillance System showed that obesity rates in adults have been exceeding 35% in nine states and, 30% in 31 different states and 25% in the other 48 states.
Being obese carries a huge range of negative health consequences and increased risk of premature deaths. Negative consequences include type 2 diabetes, stroke, hypertension, osteoarthritis, sleep apnea, urinary incontinence, body pain, high blood pressure, increased cholesterol level and sometimes mental illness.
Obese people have increased medical costs of around $1,429 billion as compared to those having normal body weight.
Bariatric surgery is a weight loss surgery that helps in losing weight by making changes in the digestive system of obese patients. It is the best treatment option for people with severe obesity. There are different types of bariatric surgery. Patients with weight loss surgery had a lower risk of premature deaths and a 59% lower risk of hypertension and a 43% lower risk of heart failure as compared to the patients with no surgery.
Patients with specific bariatric surgery, gastric bypass surgery had lower risk heart problems in general as compared to patients with no surgery.
Gastric bypass surgery, known as Roux-en- Y gastric bypass is one of the most common and safest bariatric surgeries. It produces significant long term reduction in weight loss. It produces favorable alterations in the hormones and bacteria present in the gut which helps in reducing appetite. It is associated with a reduced risk of cardiovascular disease.
The results show bariatric surgery benefits to reduce the health burdens due to obesity in the real-world-data. Senior author of the study, Abd A. Tahrani of Queen Elizabeth Hospital said that considering the availability of bariatric surgery and the lower provision in the UK as compared to other European countries that have lower obesity prevalence. Bariatric surgeries are a significant treatment option for obese people and better access helps in reducing the disease burden.
The study outcomes reveal that overall bariatric surgery wasn’t associated with significantly reducing cardiovascular disease but gastric bypass surgery showed a significant impact on cardio diseases. Overall significant decrease in all-cause mortality rate; CVD, hypertension, and heart failures were observed.
