24岁吃播博主陈紫怡因长期吃播和反复催吐导致血钾严重降低，已于2026年8月17日离世，疑与低钾引发的心脏骤停相关1。其血钾最低仅为2.3毫摩尔/升，已达重度低钾水平1。正常血钾水平为3.5-5.5毫摩尔/升，低于2.5毫摩尔/升即为重度低钾1。
医学专家指出，钾离子是心脏电活动的关键开关，低钾血症可诱发心律失常、室速、室颤、心脏骤停等严重后果1。反复催吐导致食物未被吸收就被吐出，胃液、肠液中的钾随之流失1。低钾的早期症状表现为双下肢对称性乏力、走路脚拖不动、爬楼梯腿发软等1。
专家强烈警示，不要自行在家乱吃补钾片，肾功能不佳会形成高钾血症1。根据《中国居民膳食指南》，成年人每日钾的适宜摄入量为2-4克1。此外，2021年实施的《反食品浪费法》禁止制作传播宣扬暴饮暴食的内容1。
A 24-year-old content creator known for mukbang videos, Chen Ziyi, passed away on August 17, 2026, in what medical experts suspect was related to severe hypokalemia and subsequent cardiac arrest.1 Her blood potassium level had dropped to a critically low 2.3 millimoles per liter, well below the threshold for severe deficiency.1
The condition developed as a consequence of her prolonged engagement in mukbang content creation combined with repeated self-induced vomiting.1 When food is expelled through vomiting before absorption, potassium present in gastric and intestinal fluids is lost from the body.1 Potassium plays a crucial role in cardiac electrical activity, and deficiency can trigger arrhythmias, ventricular tachycardia, ventricular fibrillation, and cardiac arrest.1 Normal blood potassium levels range from 3.5 to 5.5 millimoles per liter; levels below 2.5 millimoles per liter constitute severe hypokalemia.1
Medical experts emphasize that early symptoms of hypokalemia include symmetric weakness in both lower extremities, difficulty lifting feet while walking, and leg weakness when climbing stairs.1 They strongly caution against self-administering potassium supplements at home, as individuals with compromised kidney function risk developing dangerous high potassium levels.1 According to China's Dietary Guidelines for Residents, the recommended daily potassium intake for adults is 2 to 4 grams.1 Additionally, China's 2021 Anti-Food Waste Law prohibits the creation and dissemination of content that promotes binge eating.1
