Dr. Yoosoo Chang from the Sungkyunkwan University School of Medicine in Seoul, South Korea, and colleagues, followed the health of over 62,000 healthy young and middle-aged men and women. There were about 900 cases of chronic kidney disease (CKD) that developed in the participants over the course of the study. And participants with higher BMIs were more likely to develop the condition than others. In particular, obese participants had 6.7 cases of CKD per 1,000 persons, while the incidence in overweight people was only 3.5 cases per 1,000. The situation was even worse for obese individuals 40 years and older — 19 cases per 1,000.

The straw that broke the camels back for me was stage 3 chronic kidney disease. It is the reason I chose to have WLS and since doing so my kidneys are functioning much better putting my CKD into remission.

This is a real problem for morbidly obese patients and needs to be taken seriously.

It was my nephrologist who suggested having WLS and to this day I call him my hero. Without that push I think I would still be suffering and headed down a very scary place.
