US gold medallist Ryan Lochte attracted attention after admitting to peeing in the Olympic pool, and his teammate Michael Phelps later said that "everybody pees in the pool".
Speaking to Absolute Radio's Johnny Vaughan live from Hyde Park at BT London Live, Adlington agreed: "Every swimmer pees in the pool.
"You've got like two hours your training session, and like you can't waste time by getting out and going to the toilet.
"Like you just pee. You get used to it. I'm a distance swimmer so I keep going - so I just have to."
Adlington won bronze medals in the 400m and 800m freestyle events at London 2012.
