BMI, Type 2 Diabetes Associated With an Increased Risk of Kidney Stones

Obesity and Diabetes are Associated With Higher Risk of Kidney Stone Formation

it would be pertinent for any urologist working with patients who have a high BMI and type 2 diabetes to help them achieve a healthier body weight and better A1C number to help reduce their risk of forming kidney stones

A new study presented at the 2017 American Urological Association annual meeting in Boston has found a positive association between both obesity and diabetes and the formation of kidney stones.

“This information ties in with past studies that have looked at the elevated risk of kidney stones among patients with type 2 diabetes and obesity,” stated Dr. David Samadi. “From those studies we know that patients with hyperglycemia and glycosuria have a higher risk of being stone formers due to the fact of having an increased excretion of urinary oxalate. This condition is known as hyperoxaluria which is an excessive urinary excretion of oxalate that can lead to calcium oxalate kidney stones.”

Patients with high body mass index (BMI) and who also have type 2 diabetes are known to have a higher association of kidney stone risk. There is also a known correlation between the higher a person’s BMI is, the higher the amount of the excretion of urinary oxalate. Researchers wanted to find out if there was also an associated link to a person’s hemoglobin A1C, a marker that is used to monitor blood sugar levels in the past few months.

“The researchers began by analyzing 1,428 twenty-four hour urine collections that were collected between 2004 and 2015,” explained Dr. Samadi. “They then analyzed 665 unique non-cystinuric adult stone formers looking to see if there were an association between urinary oxalate excretion and their BMI, age,…
