Comparative StudyBariatric surgery and progression of chronic kidney disease.
Obesity is an independent predictor for the development and progression of chronic kidney disease (CKD). The effect of weight reduction on the progression of kidney disease in patients with pre-existing CKD is unclear. ⋯ The renal function of patients with CKD might improve after bariatric surgery. Larger and long-term studies are warranted to further analyze the effect of bariatric surgery on proteinuria and hard end-points such as the development of end-stage renal disease.

Comparative StudyCardiac remodeling after substantial weight loss: a prospective cardiac magnetic resonance study after bariatric surgery.
Obesity is a risk factor for left ventricular (LV) hypertrophy and excess cardiovascular disease and mortality. Substantial weight loss is associated with a decrease in cardiovascular mortality. Using volumetric cardiovascular magnetic resonance (CMR) imaging, we studied changes in cardiac anatomy and systolic function in women undergoing substantial weight loss in a university hospital. ⋯ In morbidly obese women, substantial weight loss was associated with a reduction of LV and RV mass. The decrease in LV mass was linearly related to the reduction in BMI, independent of changes in blood pressure, and might partially explain the reduction in cardiovascular mortality associated with substantial weight loss. The BMI was a predictor of LV mass in this population.
