Walliams was outspoken about his diagnosis with bipolar disorder.
As part of the British charity event Sport Relief, Walliams swam the English Channel on July 4, 2006, raising over one million pounds for the charity. On March 7, 2008, he swam the Strait of Gibraltar from Spain to Morocco for Sport Relief. On September 5-12, he swam the length of the River Thames, raising over two million pounds but contracting an intestinal disease and injuring a disc in his back so badly that he underwent spinal surgery in 2013.
As a stunt for the Comic Relief charity on March 5-6, 2011, Walliams undertook "24-hour Panel People," in which he hosted or guested on 19 episodes of British "panel shows" such as "Never Mind the Buzzcocks" and "They Think It's All Over" over the course of 24 hours.
