"I actually suffer from lactose intolerance and IBS so last night's late night snack on @bigbrothercbs of beef jerky sticks, candy and warm milk was a stomach ache waiting to happen," he wrote in the caption. "The bad thing is @peptobismol_us hasn't reached out to me for an endorsement deal yet."

Representatives for Odom did not immediately respond to Insider's request for comment.

Odom is one of eleven "HouseGuests" on the CBS show's third season, which premiered on Wednesday. The show follows a group of celebrities living in a house together and competing for a grand prize of $250,000. When the CBS cameras aren't rolling, cameras and mics around the house stream uncensored live feeds for fans to watch.

This season also features comedian Chris Kattan, former Miss USA Shanna Moakler, and entertainer Todrick Hall. Odom said in the clip that Hall heard the pooping incident.

Odom is no stranger to reality television. Although he played for the Los Angeles Lakers for seven seasons, Odom is also known for his previous marriage to Khloe Kardashian.

The couple's wedding and marriage were featured on "Keeping Up with the Kardashians" and they starred in their own reality show, "Khloe & Lamar," from 2011 to 2012. In another clip from this season of "Celebrity Big Brother," Odom said he missed Kardashian "so much" and wishes he could "take that time back" when they were married.
