On August 27, 2010, Kim received a lumbar microdiscectomy surgery to relieve a herniated disk. Kim's management company, 101 Entertainment stated, “Kim Jong-kook carried on with his daily activities without knowing that he had a ruptured disk. However, he did feel pain, but did not think much of it, and he endured his condition with painkillers while filming SBS Running Man." In January 2015, he was a guest on the popular talk show, Healing Camp, where he shed light on many personal controversies, including his choice to work as a public service worker instead of an active-duty soldier during his mandatory military enlistment, which was partly due to the aforementioned back issues. In December 2019, his hernia surgery was documented on My Little Old Boy.
