TWICE's Jeongyeon reveals weight gain was due to Cushing's syndrome from steroid treatment

For those unfamiliar, K-pop singer Jeongyeon of TWICE opened up about her health issues, particularly her sudden weight gain over the past few years. According to a report by South Korean health outlet KorMedi on July 25, 2024, the singer disclosed that she had been diagnosed with Cushing's syndrome. She said that the condition was triggered by the use of steroid medication prescribed to treat a herniated disc in her neck in 2020.

Jeongyeon said that the steroids, which she used during her rehabilitation, led to a sudden gain in weight. She described how her weight gain was involuntary, a result of the treatment's side effects.

She also shared that she had become more careful, as she tried to control her condition with constant treatment and exercise, such as tennis and surfing. She also emphasized the importance of mental stability.

"Since I had to take a break once, I try to keep my mind stable. These days, I am making an effort to find new hobbies, and it gives me strength for my life," she shared.

The singer had taken a step back from her activities before due to numerous health problems.
