Bariatric Surgery Lowers Kidney Disease Risk
The study, recently published in the International Journal of Obesity, adds to the growing stack of research that weight-loss surgery carries many health benefits.
Obesity is a dangerous condition. It often causes high blood pressure, cardiovascular diseases and type 2 diabetes, which in turn may lead to complications such as chronic kidney disease. Diabetes and high blood pressure are the most common causes of kidney disease.
If you have chronic kidney disease, it means your kidneys are damaged and can’t filter blood the way they should. If you have type 2 diabetes and high blood pressure, it’s important to keep both conditions under control through medication and healthy eating. You can protect your kidneys by keeping your blood pressure at or less than the goal set by your doctor. For most people, the blood pressure goal is less than 140/90 mm Hg.
Obesity is also an independent risk factor in developing chronic kidney disease. Different obesity treatment strategies include: life style interventions, dietary modification, pharmacological and surgical treatment, such as bariatric surgery.
Many recent studies of patients with obesity have shown that weight-loss surgery is currently the most efficient way to achieve and maintain significant long-term weight loss. It also prevents obesity-related complications such as type 2 diabetes.
Researchers at Sahlgrenska Academy followed roughly 4,000 people with obesity for more than 20 years. Half of the patients received weight-loss surgery, and the other half were treated with conventional non-surgical methods in the primary health care. They found that the patients that underwent weight-loss surgery ran a significantly lower risk of developing severe chronic kidney disease and kidney failure, when compared to conventionally treated patients.
Patients who had kidney damage at the start of the study benefited most from surgical treatment, the study found. Researchers said their study shows that surgery prevents progression of pre-existing kidney injury towards renal failure.
