How Bariatric Surgery Can Minimise Your Cardiac Risk

27 May 2021

Bariatric Surgery is used to help people who are considered overweight or obese, who have struggled to maintain a healthy weight using other methods such as diet, exercise and medication. According to the World Health Organisation, a person is considered obese when their body mass index (BMI) is over 30. Candidates for Bariatric Surgery usually have a BMI of over 40 and or 30 and above with metabolic comorbidities such as uncontrolled diabetes.  However, many other health factors may come into play that should be thoroughly discussed with your doctor when inquiring about bariatric surgery. The goal of bariatric surgery is to help bring your BMI down by reducing the stomach size. Please see the weight loss tab on our website to learn more about the different types of bariatric surgery.

Those with obesity are at a higher risk for a variety of health complications, particularly in regards to cardiovascular diseases. When a person is overweight or obese, fatty material can accumulate in the blood vessels that pump blood around the body and to your heart. If too much fatty material builds up, it can cause high blood pressure, as your arteries resist the blood flow. To learn more about the connection between obesity and high blood pressure, please see this article. If the artery becomes completely clogged, it can cause a heart attack or a stroke if it is a blood vessel leading to the brain. Those suffering from long-term obesity are therefore at a much higher risk of these issues.

However, there is significant evidence to suggest that bariatric surgery can considerably minimise your cardiac risk. For example, an extensive study published at the beginning of last year in Europe found:

“…There were 60% fewer fatal and non-fatal heart attacks and strokes among 3,701 men and women who received bariatric surgery compared to the same number of patients who did not, during an average of 11 years following the surgery.”1

The study also found that people that undertook bariatric surgery also were at a lower risk for type 2 diabetes. Ultimately, in losing a significant amount of weight and moving out of the BMI category that is considered obese, you are taking a lot of stress off your heart.

It is important to remember that it is not solely the bariatric surgery itself that can bring down your cardiac risk but also the other significant lifestyle changes you make after the surgery. After your bariatric surgery, your doctor will assist you in implementing changes such as increasing your level of daily exercise and eating a healthy diet with smaller portion sizes. If you follow the advice from your doctor carefully, you will see quite rapid weight loss. For example, those that undergo Lap Band surgery (40%), sleeve gastrectomy (70%) and gastric bypass (80%) can excess weight loss respectively during their first year. However, suppose someone falls into old habits of over-eating or eating overly fatty or sugary foods. In that case, this can cause complications and may even lead to the reversal of the surgery.
