To identify whether obesity is associated with a UTI diagnosis, Baltimore researchers evaluated insurance claims of 95,962 subjects over a five-year period (from 2002 through 2006).

They found that, as BMI increased, the odds of being diagnosed with a UTI increased as well.

Increased alkalinity is proven to augment citraturia, a known factor for calcium stones. Malate increases the amount of alkali delivered.
