Kang Ye Won revealed she suffered a drastic weight loss.
The April 5 airing of KBS 2TV's 'Entertainment Weekly' included an interview with Kang Ye Won in light of her new film 'Watching.'
During the talk, Kang Ye Won revealed she recently found out she had hyperthyroidism and said, "'Watching' is a film that required a lot of running. It was so hard. So I really ate a lot. I had two to three portions of rice per meal but I didn't gain weight. I've actually lost weight and dropped down to 43kg (95 lbs). I felt like I was going to die if I keep up this way so I went to the hospital."
