TWICE member Chaeyoung is taking a break from all activities following a diagnosis of vasovagal syncope. JYP Entertainment announced on November 20 that she needs additional rest after medical tests. The condition is a common cause of sudden fainting spells.
JYP Entertainment issued an official statement on November 20 announcing that Chaeyoung has been diagnosed with vasovagal syncope. Following medical consultations and tests, doctors determined she requires a longer recovery period.
“Chaeyoung was recently diagnosed with vasovagal syncope, and after careful examinations, it was concluded that she needs additional rest,” the agency stated. “She will temporarily suspend activities to focus on treatment and recovery.” JYP added that Chaeyoung is “deeply disappointed” but is prioritizing her health, requesting fans' understanding and support.
Vasovagal syncope is one of the most common causes of fainting, occurring when the body overreacts to triggers, causing a rapid drop in blood pressure and heart rate that momentarily cuts blood flow to the brain. Most episodes resolve within seconds to a minute and are not life-threatening, though falls can lead to injuries.
Common triggers include prolonged standing, hot or poorly ventilated environments, sudden pain or fear, and seeing blood or needles. It is more prevalent in individuals with low blood pressure, low body fluid levels, or a history of fainting.
Recognizing early warning signs is essential. These may include darkening or narrowing vision, dizziness, cold sweat, nausea, ringing in the ears, or intense fatigue. Sitting or lying down and elevating the legs at the first sign can prevent a full episode.
Diagnosis typically involves an electrocardiogram to rule out arrhythmias or heart disease, and a tilt-table test to assess autonomic nervous system responses. If fainting recurs, occurs during exercise, or accompanies chest pain or shortness of breath, underlying heart conditions must be investigated.
To prevent episodes, maintaining hydration and increasing salt intake helps preserve blood volume. When standing for long periods, crossing legs or flexing calf muscles improves circulation. Regular exercise, adequate sleep, and balanced nutrition are key, while excessive dieting or dehydration raises risks. For frequent cases, medication may be needed, and experts recommend carrying a “syncope action card” with symptoms, response steps, and emergency contacts.
