On the March 15th broadcast of SBS's "Strong Heart", SISTAR's Hyorin shared a story about her health complications during her infancy years. Hyorin started, "Unlike my current image, as a child I was incredibly weak, and my body would always be in some sort of trouble. When my mother gave birth to me, I weighed in at 4.2kg (about 9 lbs)." According to Hyorin, water had filled her stomach, which led her to become a premature birth.  Bile was unable to be passed through her intestines, which eventually damaged her liver, causing a biliary atresia. Although the required surgery had low chances of sustaining life, Hyorin was able to survive the 10-hour long surgery. A year later, however, she was diagnosed with intussusception (a medical condition where parts of the intestine folds over into another section of the intestine) and received surgery for enterectomy. The audience saw that Hyorin couldn't hide her anxiety while revealing the shocking facts, but they praised her for managing to keep a bright and cheerful appearance throughout the episode.
