During the February 16 broadcast of SBS' 'Laws of the Jungle in Patagonia', DIA member Jung Chae Yeon had to leave the premises after suddenly falling ill.

With Captain Kim Byung Man's team literally starving for 70 hours, Jung Chae Yeon couldn't handle the pain and expressed, "My stomach really hurts," crying.

Later on, she commented, "I got upset since my body couldn't keep up.  I felt a bit sick in the morning but I didn't want to cause trouble or anything so I decided to wait it out."

A medical staff on site explained, "It seems the pain was triggered after going without food for a long time."  The idol singer was immediately rushed back to base camp to rest.
