The nerve conditions that affected Lee Sang-soon, HyunA and TWICE's Chaeyoung

Singer Lee Sang-soon has taken a break from his radio show after saying he has vagus nerve dysfunction, drawing attention to vasovagal syncope and other nerve-related fainting conditions. He said he felt unwell last Wednesday, underwent tests and consultations, and was told to rest. HyunA and TWICE’s Chaeyoung have also previously spoken about vasovagal syncope. Lee’s agency said it will support his recovery and adjust his schedule.

Lee Sang-soon said he suddenly felt unwell last Wednesday and has undergone various tests and consultations since then.

He had shown signs of illness during the Aug. 26 live broadcast of MBC FM4U radio show A Perfect Day with Lee Sang-soon.

HyunA said she was diagnosed with vasovagal syncope after collapsing several times and undergoing tests including an EEG at a university hospital.

TWICE’s Chaeyoung temporarily suspended her activities last year after being diagnosed with vasovagal syncope.

Vasovagal syncope occurs when the nervous system overreacts to triggers such as intense physical or emotional stress, causing blood pressure and sometimes heart rate to drop.

Singer Lee Sang-soon’s decision to take a break from his radio show over what he described as “vagus nerve dysfunction” has drawn attention to health conditions involving the nerve. Other celebrities, including HyunA and TWICE’s Chaeyoung, have previously spoken about experiencing vasovagal syncope, a form of fainting.

The singer and radio show host explained his recent absence from the show in a social media post Sunday.

“I’m sorry to listeners for taking time off from the radio show without any explanation,” he wrote. “I suddenly felt unwell last Wednesday and couldn’t host the show. Since then, I’ve undergone various tests and consultations.”

He added that he was still awaiting further testing but had been advised by his doctors to rest because of the neurological issue. Although his recovery remains unclear, Lee plans to focus on recuperating for now, following doctors’ advice that his condition could improve gradually with sufficient rest.

“Since I don’t know when I’ll recover, I kept thinking, ‘If I feel better tomorrow, I should get back to hosting.’ That’s why it took me so long to write this,” Lee said. “I’ll take this opportunity to give myself enough time to recover properly before returning. Please don’t worry too much. I’ll be resting and recovering, so please bear with me a little longer.”

The singer had previously shown signs of ill health during the Aug. 26 live broadcast of his MBC FM4U radio show, “A Perfect Day with Lee Sang-soon.” Feeling unwell, he rested in the infirmary and returned to the studio with only about 20 minutes left in the broadcast. His continued absence from subsequent live broadcasts prompted concern about his health.

Lee’s disclosure has also renewed attention to other celebrities who have experienced vasovagal syncope.

Among them is HyunA, who previously revealed that she had been diagnosed with vasovagal syncope after also experiencing depression and panic disorder.

“At first, my vision went blurry, and then I just collapsed. It happened several times,” she previously recalled. “I was going to brush it off as another symptom of panic disorder, but on my doctor’s advice, I went to a university hospital for various tests, including an EEG. That’s when I learned there was a condition called vasovagal syncope.”

More recently, she collapsed onstage again during a performance, alarming fans.

TWICE’s Chaeyoung also temporarily suspended her activities last year after being diagnosed with vasovagal syncope.

Actor Kim Jung-nan has spoken about losing consciousness and hitting her chin on a bedside table, saying, “I nearly died after fainting.”

Vasovagal syncope occurs when the nervous system overreacts to triggers such as intense physical or emotional stress, causing blood pressure and sometimes heart rate to drop. This temporarily reduces blood flow to the brain, leading to a loss of consciousness. Warning signs can include dizziness, cold sweats, nausea and blurred vision.

Medical evaluation is important, particularly when fainting recurs, to rule out other heart or neurological conditions.

With Lee still awaiting further testing, the timing of his return to broadcasting will depend on his recovery. His agency, Antenna, said it would “provide full support so the artist can focus entirely on recovering” and adjust his upcoming schedule accordingly.

歌手李尚顺因自述患有迷走神经功能障碍而暂停了电台节目，此举引发了人们对血管迷走性晕厥及其他神经相关晕厥疾病的关注。他表示上周三感到身体不适，接受了检查和咨询，并被建议休息。泫雅和TWICE成员彩瑛此前也曾谈及过血管迷走性晕厥。李尚顺的经纪公司表示将全力支持他的康复，并调整他的行程安排。

李相顺表示，他上周三突然感到身体不适，此后接受了各种检查和会诊。

他在 8 月 26 日与李尚顺一起直播 MBC FM4U 广播节目《完美的一天》时，就表现出了生病的迹象。

泫雅表示，她在大学医院多次晕倒并接受了包括脑电图在内的检查后，被诊断出患有血管迷走性晕厥。

TWICE成员彩瑛去年被诊断出患有血管迷走性晕厥后，暂时停止了演艺活动。

血管迷走性晕厥是指神经系统对诸如强烈的身体或情绪压力等诱因反应过度，导致血压下降，有时还会导致心率下降。

歌手李尚顺因自称“迷走神经功能障碍”而暂停主持电台节目，此事引发了人们对迷走神经相关疾病的关注。此前，泫雅和TWICE成员彩瑛等其他艺人也曾公开谈论过自己患有血管迷走性晕厥，这是一种晕厥症状。

这位歌手兼电台节目主持人周日在社交媒体上发帖解释了他最近缺席节目的原因。

“很抱歉，我没有任何解释就暂停了广播节目，耽误了听众的时间，”他写道。“上周三我突然感到身体不适，无法主持节目。从那以后，我接受了各种检查和咨询。”

他补充说，他仍在等待进一步的检查结果，但医生建议他因神经系统问题而休息。尽管他的康复情况尚不明朗，但李计划目前专注于休养，因为医生建议他充分休息后病情会逐渐好转。

“因为不知道什么时候才能恢复，我一直在想，‘如果明天感觉好些，就应该回去主持节目。’所以才拖了这么久才写这篇稿子，”李说。“我会利用这段时间好好休息，彻底恢复，然后再回来。请大家不要太担心。我会好好休息恢复，请再多给我一些时间。”

这位歌手此前在8月26日直播的MBC FM4U广播节目《与李尚顺的完美一天》中就已显露身体不适。他感到身体不适后前往医务室休息，并在节目还剩约20分钟时返回演播室。此后他持续缺席直播节目，引发了人们对他健康状况的担忧。

李的披露也重新引起了人们对其他曾患有血管迷走性晕厥的名人的关注。

其中包括泫雅，她此前透露，在经历了抑郁症和恐慌症之后，她被诊断出患有血管迷走性晕厥。

“起初，我的视线变得模糊，然后就晕倒了。这种情况发生了好几次，”她之前回忆道。“我本来以为这只是恐慌症的又一个症状，但听从医生的建议，我去了一家大学医院做了各种检查，包括脑电图。正是在那时，我才知道有一种叫做血管迷走性晕厥的疾病。”

最近，她在演出中再次晕倒在舞台上，令粉丝们感到担忧。

TWICE 成员彩瑛去年被诊断出患有血管迷走性晕厥后，也曾暂时停止活动。

演员金正兰曾谈到自己失去意识，下巴撞到床头柜上，她说：“我晕倒后差点死了。”

血管迷走性晕厥是指神经系统对诸如剧烈的身体或情绪压力等诱因反应过度，导致血压下降，有时甚至心率下降。这会暂时减少流向大脑的血液，导致意识丧失。预警信号可能包括头晕、盗汗、恶心和视力模糊。

医疗评估非常重要，尤其是在晕厥反复发生时，以便排除其他心脏或神经系统疾病。

由于李尚彦仍在等待进一步的检测结果，他何时回归荧屏将取决于他的康复情况。他的经纪公司Antenna表示，将“全力支持艺人全身心投入康复”，并据此调整他接下来的行程安排。
