Six years ago, a study found that about 40 percent of runners suffer acute kidney injury after marathons. Nephrologist Chirag Parikh, a professor of medicine at Yale, was unsure what to tell his patients. He knew that running marathons tends to be associated with at least temporary kidney damage, but he didn’t know how or why exactly that happened. Today he’s a step closer to understanding, as his lab has published a new study elaborating on the relationship. Dr. Parikh found that the rate of acute kidney injury was likely closer to 75 percent. And the effect was not subtle.
