Living Donor Research Living Donor Risks Living Kidney Donor

Obesity and Living Kidney Donation



The link between obesity and diabetes, hypertension, and eventual kidney dysfunction is well recognized.


Glad to see the corroboration.

Now the study (emphasis mine):


…BMI was evaluated in 532 donors over 11 years from 2002-2012. Measurements were made pre-operatively, at 1 year, and at the present time. Follow-up range varied from 12 month to 11 years dependent on the date of donation. Of the 532 patients queried, 100 patients had long-term results. At 1 year there was an overall decrease in BMI, however at anytime after the 1st year postoperative, BMI trended upwards, with more than half of overweight patients (BMI 25-30) at the time of donation dipping into the obese range (BMI > 30). Given these results and recognizing the attendant risks –especially with the background of a single kidney- we have initiated further lifestyle and nutrition counseling at our center and are considering more stringent preoperative weight control policy.


So utilizing overweight folks as live kidney donors isn’t a good idea? And there are a lot of health risks to being obese, which are exacerbated by having only one kidney?

Hmm. Someone should tell these people.
