“挣钱固然重要,身体永远是第一位。”这是24岁百万粉丝吃播博主“干饭莹莹”(本名陈紫怡)在生前的叮嘱。

9月4日,陈紫怡的父母在社交媒体账号发布讣告,称陈紫怡已于2026年8月17日离世。

生前最后一条视频中,她自述血钾最低仅2.3毫摩尔/升,因低钾住院,坦言身体问题和长期吃播、反复催吐相关。

有知情人透露,莹莹长期处于低钾状态,其离世疑与低钾引发的心脏骤停相关。

不少网友心生疑惑:明明一直在大量吃东西,为何还会出现凶险的低钾?

钾离子相当于心脏电活动的关键开关

低到这个数值很凶险!

“一般我们正常血钾水平是3.5‑5.5毫摩尔/升。”浙江省人民医院朝晖院区急诊医学科庞凌霄副主任医师介绍,低于3.5毫摩尔/升即为低钾血症;3.0‑3.4毫摩尔/升为轻度低钾,2.5‑2.9毫摩尔/升属于中度低钾,血钾低于2.5毫摩尔/升就是重度低钾。

博主莹莹测出的2.3毫摩尔/升,已经落到重度低钾区间。“如果我们临床遇到这样子的指标,基本都是要放到抢救室里面去的。”庞凌霄说。

钾离子相当于心脏电活动的关键开关,心脏每一次跳动,都依靠心肌的生物电传导完成。“血钾高了或者低了,都会扰乱心肌电信号,诱发心律失常,严重时会出现室速、室颤,直接危及生命。”严重低钾,完全可能诱发心脏骤停。

钾不光作用于心肌,同时参与全身神经信号传递、肌肉收缩,胃肠道平滑肌、四肢骨骼肌的运转都离不开它,低钾的伤害是全身性的,绝不止简单的浑身乏力。

低钾早期的表现非常隐蔽,很容易被当成疲劳、中暑。“低钾最典型的首发症状就是双下肢对称性乏力,走路脚拖不动,爬楼梯腿发软,站久了就想蹲下。”庞凌霄表示。随着血钾持续走低,无力感会蔓延到躯干、上肢,甚至累及呼吸肌,“到这个程度,人连呼吸都会吃力。”

个体的耐受差异很大,有的人血钾已经跌到重度水平,却仅仅只有轻微疲惫感。“千万不能靠自我感觉判断有没有低钾,抽血化验才是金标准。”

吃得多也会缺钾?

催吐、腹泻、不当减肥都在偷走体内的钾

很多人不解,正常吃饭为什么还会缺钾?

庞凌霄解释,普通人均衡饮食,身体可以维持钾的动态平衡;但像莹莹这样反复催吐,情况就完全不一样。“食物吃进去,还没完成吸收就被吐掉,胃液、肠液里大量的钾随之流失,补得少、丢得多,低钾就会反反复复找上门。”

除催吐之外,生活里不少场景都在消耗体内钾元素:

高强度运动大量出汗后只喝白水;

急性肠胃炎反复上吐下泻;

部分甲亢、离子通道病,同样会引发低钾。

“现在不少人打减肥针,呕吐反应比较明显,吐得厉害也会造成钾大量丢失,这部分人群尤其要当心。”庞凌霄提醒。

“减肥本身没问题,合理饮食加适度运动才是值得提倡的方式。”浙大一院庆春院区急诊科主任陆远强说,可不少人为求快速瘦身,轻信来路不明的减肥药。“有些减肥药短期减重效果看着很好,却会严重扰乱体内电解质,对心脏、肾脏带来损伤,风险极高。”

2021年实施的《反食品浪费法》明确禁止制作传播宣扬暴饮暴食的内容,监管也持续整治畸形吃播。不管是暴饮暴食后催吐,还是乱吃减肥药激进减重,都是在透支身体。庞凌霄感慨:“身体已经用住院给出警告,还继续重复伤害行为,风险只会不断叠加。”

补钾切勿自行吃补钾片

不同人群要区别对待

出现乏力之后,很多人第一反应就是自己买补钾药片服用。对此庞凌霄再三警示:“千万不要自己在家乱吃补钾片,不建议普通人居家自行补钾。”

钾主要依靠肾脏代谢排出,一旦肾功能不佳,补进去的钾排不出去,会形成高钾血症,同样会诱发恶性心律失常,威胁心脏安全。“就算肾功能正常,补钾药也不能像吃维生素那样随便吃。”庞凌霄介绍,临床上就算给腹泻病人开具补钾药物,也会明确告知服用周期,血钾恢复正常就要及时停药。

面对不同情况,处理方式也不一样:

马拉松这类大量出汗之后的疲惫,可以适当饮用含钾、钠成分的电解质饮料;

但如果是上吐下泻引发的不适,务必及时就医,不光要排查血钾,还要评估脱水、感染情况,呕吐严重的患者,需要在院内静脉补钾。

健康人群日常补钾优先选择食补。《中国居民膳食指南》建议,成年人每日钾适宜摄入量为2‑4克。

日常高钾食物清单

蔬菜:菠菜、苋菜、莴笋等深绿色叶菜;土豆、红薯、山药等薯类;鲜香菇、金针菇等菌菇。

水果:香蕉、橙子、柚子、哈密瓜、草莓。

其他:黄豆、黑豆等豆类;三文鱼、鳕鱼等鱼类;牛奶、酸奶等乳制品、全谷物。

高血压、心血管疾病人群,可以适当增加高钾食物摄入,钾能够帮助身体排出多余钠,辅助血压管控。保证睡眠、适度运动,减少浓茶、过量咖啡摄入,也有利于钾的吸收利用。

提醒:

补钾并非多多益善

肾功能不全、透析患者排钾能力受损,切忌盲目大量食补高钾食物,一切遵从医嘱。老年人、长期服药人群,如果反复心慌、肢体乏力,不要单纯依靠食补硬扛,及时就医寻找低钾根源。部分降压药会影响血钾水平,需要医生评估调整用药。

轻度低钾可在医生指导下调整饮食、口服补钾;一旦发展为重度低钾,伴随下肢无力、心慌心悸,食补远远不够,必须立刻就医,必要时静脉补钾。

身体发出的预警信号

值得每个人重视

流量、收益、身材固然重要

但身体健康才是一切的基础

Nutritionists point out that to reduce triglycerides, we need to pay attention to four major dietary blind spots. Just cutting out oil is not enough.

Nutritionist Zeng Jianming emphasized that high triglycerides do not necessarily come from excessive fat intake. Sugar, refined starch, alcohol heat and excess total calories can also cause the liver to synthesize triglycerides. He listed four common dietary blind spots: excessive refined starch, excessive fruit intake, occasional heavy drinking, and normal weight but fatty liver or insulin resistance. He recommended adjustments in four directions: controlling sugar and starch, limiting alcohol, adjusting starch quality and quantity, and combining weight loss exercises.

Taiwan expands publicly funded nine-valent HPV vaccine vaccination to all junior high school students, ranking first in East Asia for both men and women

Since September 2014, Taiwan has expanded the scope of the publicly funded nine-valent HPV vaccine to all junior high school students, both men and women, becoming the first country in East Asia to provide boys with a complete two-dose vaccine. In the first year, approximately 213,000 junior high school students benefited, with the first-dose vaccination rate reaching 81.6% for boys and 91.9% for girls. Information from the Ministry of Health and Welfare shows that HPV can cause a variety of cancers. Experts emphasize that the vaccine can prevent more than 90% of cancers related to highly carcinogenic types. They also call on parents to sign the consent form as arranged by the school, do not fast before vaccination, and observe for 15 minutes after vaccination.
