Chinese Mukbang Influencer Dies at 24: How Low Potassium Can Affect the Heart
The reported death of Chinese food-content creator Yingying has brought attention to hypokalaemia—a potentially dangerous shortage of potassium that can affect muscles, nerves and the heart’s rhythm.

HEALTH NEWS — Chinese food-content creator Yingying, also known as Chen Ziyi, reportedly died at age 24 after previously telling followers from hospital that she had dangerously low potassium and had been vomiting.
Her parents confirmed her death through social media. However, an official medical cause of death has not been publicly released.
Reports referring to cardiac arrest should therefore be presented as reported information—not as a confirmed conclusion that low potassium or mukbang content caused her death.
Yingying’s family announced her death. Some outlets reported cardiac arrest, while Yingying had previously described low potassium and vomiting. No publicly released medical statement has confirmed the precise cause or a direct link between these factors.
What Is Potassium and Why Does It Matter?
Potassium is an electrolyte—a mineral that carries an electrical charge when dissolved in body fluids. It helps nerves send signals and muscles contract normally.
The heart is a muscle controlled by electrical activity, so potassium levels must remain within a healthy range. Both very low and very high potassium can disturb the heart’s rhythm.
Potassium is not merely a nutrient associated with bananas. It forms part of the body’s electrical system and is tightly regulated by the kidneys and hormones.
What Is Hypokalaemia?
Hypokalaemia means the potassium level in the blood is lower than normal. Mild cases may cause no obvious symptoms, but larger reductions can produce weakness, fatigue, muscle cramps, constipation, tingling or abnormal heart rhythms.
Possible causes include repeated vomiting or diarrhoea, certain diuretics and laxatives, some hormonal or kidney conditions, low magnesium and inadequate intake combined with continuing losses.
A blood test is needed for diagnosis. Clinicians may also check kidney function, magnesium and an electrocardiogram, depending on the symptoms and severity.
How Can Vomiting Lower Potassium?
Vomiting removes fluid and stomach contents. The body’s response to fluid loss can increase potassium loss through the kidneys, while reduced food and fluid intake may make replacement more difficult.
Repeated vomiting can also disturb chloride, sodium, acid–base balance and hydration—not only potassium.
Get prompt help if vomiting persists, fluids cannot be kept down, urine becomes very limited, or there is marked weakness, dizziness, confusion, fainting, chest pain or an irregular heartbeat.
How Can Low Potassium Affect the Heart?
Potassium helps heart cells reset their electrical charge between beats. When levels fall too low, this electrical recovery can be disrupted, making abnormal rhythms more likely.
The risk depends on how low the level is, how quickly it fell, other electrolyte abnormalities, underlying heart disease and medicines that also affect heart rhythm.
Severe hypokalaemia can be associated with dangerous arrhythmias, but an ECG and clinical assessment are needed.
Potassium helps heart cells conduct and reset electrical signals between beats.
Low levels may contribute to weakness, cramps and, in severe cases, paralysis.
Electrolytes help nerves communicate with muscles and other tissues.
A laboratory test is needed to identify low potassium accurately.
Warning Signs That Need Medical Attention
Warning signs may include:
- Persistent vomiting or diarrhoea
- Difficulty keeping fluids down
- Severe or worsening weakness
- A racing or irregular heartbeat
- Dizziness, fainting or collapse
- Chest pain, confusion or breathing difficulty
Chest pain, fainting, severe breathing difficulty, confusion, collapse or a sustained irregular heartbeat require urgent care. In Singapore, call 995 for a medical emergency.
Can Food Correct Severe Low Potassium?
Foods such as beans, potatoes, leafy vegetables, tomatoes, avocado, bananas and some dairy products contain potassium and can support a balanced diet.
However, food is not a reliable emergency treatment for severe hypokalaemia. Treatment depends on the measured level, symptoms, ECG findings, kidney function and underlying cause.
Too much potassium can also be dangerous, particularly for people with kidney disease or those taking certain medicines. Supplements should only be used with appropriate medical guidance.
The Health Risks Behind Extreme-Eating Content
Mukbang content varies widely and does not automatically mean that a creator has an eating disorder or medical problem.
However, repeated extreme intake, rapid eating, compensatory vomiting or prolonged restriction can carry health risks.
Possible concerns include choking, reflux, vomiting, dehydration, electrolyte disturbances and an unhealthy relationship with food.
Viewers should avoid copying extreme eating challenges, especially when the creator’s health circumstances are unknown.
This story should be covered as an electrolyte-awareness article, not as proof that mukbang caused a death. The important message is that persistent vomiting and severe low potassium can require urgent medical care.
Key Takeaways
- Yingying’s family confirmed her death, but an official medical cause has not been publicly disclosed.
- Low potassium can affect muscles, nerves and the heart’s electrical rhythm.
- Repeated vomiting can contribute to dehydration and electrolyte disturbances.
- Persistent vomiting, severe weakness, palpitations or fainting need medical assessment.
- Food should not replace medical treatment for severe hypokalaemia.
- Potassium supplements can be harmful when taken unnecessarily or in excess.
- Do not claim that mukbang or low potassium definitively caused Yingying’s death.
