K-pop singer and actor IU is drawing public attention for a rare ear disorder after worsening symptoms of patulous Eustachian tube (PET) dysfunction forced her to postpone her upcoming album release and cancel a scheduled September concert.
With news of her ear condition already having disrupted her highly anticipated comeback plans, many are asking what exactly PET dysfunction is and why it poses such a devastating setback for a vocalist.
On Monday, the 33-year-old artist opened up about her ongoing struggle on the fan communication platform Berriz.
"While it does not affect my daily life, the symptoms persist day and night, making it difficult to maintain my condition when singing," IU wrote, apologizing to fans for the schedule changes.
