• Pinyin (with tone marks): chī huài dùzi
• Part of Speech: Verb Phrase
• HSK Level: N/A (Extremely common in daily conversation, but not on the official HSK lists)
• Concise Definition: To get sick to your stomach from eating bad or contaminated food.
• In a Nutshell: This is a highly literal and descriptive phrase. It perfectly captures the cause-and-effect relationship: the action of “eating” (吃) resulted in something “bad” (坏) happening to your “stomach” (肚子). It's the go-to expression for that unfortunate, all-too-common experience of food-related gastrointestinal distress.

• 吃 (chī): To eat. This is one of the most fundamental characters in Chinese, originating from a pictogram of a mouth and a person.
• 坏 (huài): Bad, spoiled, broken, ruined. In this context, it acts as a “resultative complement,” indicating the negative result of the verb “eat.”
• 肚子 (dùzi): Stomach, belly, abdomen.
  • 肚 (dù): A pictograph of a pregnant belly, representing the abdomen.
  • 子 (zi): A common noun suffix with no specific meaning here.

These characters combine logically and literally: The action of eating (吃) leads to a bad (坏) result in the stomach (肚子).

Food is arguably the cornerstone of Chinese culture, and with that comes a heightened awareness of food safety, freshness, and its effects on the body. While Chinese cuisine is celebrated worldwide, the reality of street food, different hygiene standards, and unfamiliar ingredients means that `吃坏肚子` is a common topic of conversation for both locals and foreigners. A Westerner might say, “I have an upset stomach,” which is a general statement about a symptom. Or they might say, “I got food poisoning,” which sounds more clinical and severe. `吃坏肚子` sits comfortably in the middle and is more descriptive. It specifically blames the food as the cause of the stomach problem. This reflects a practical, cause-and-effect worldview that is common in everyday Chinese language. It's less of a medical diagnosis and more of a common-sense description of a situation, making it highly relatable and frequently used. It's a shared experience that everyone understands and sympathizes with.

`吃坏肚子` is an extremely common, informal phrase used in everyday life. You would use it in almost any situation where you need to explain this specific ailment.

• Explaining an Absence: Calling in sick to a casual work environment or telling a friend why you can't make it to a dinner party.
• At the Doctor's Office: While a doctor might use more technical terms, starting with `医生，我好像吃坏肚子了 (Yīshēng, wǒ hǎoxiàng chī huài dùzi le)` is the perfect way to describe your initial symptoms.
• Warning a Friend: You can warn a friend about a specific restaurant or dish. For example, `别吃那个，小心吃坏肚子 (Bié chī nàge, xiǎoxīn chī huài dùzi)`.
• Social Media: People often post about their misfortunes, and complaining about a case of `吃坏肚子` after trying a new restaurant is a common trope.

Its connotation is neutral to negative (as it describes a bad experience), and it is used in informal to semi-formal contexts. For a very formal report, one might use the clinical term `食物中毒 (shíwù zhòngdú)`.

• Example 10:
  • 为了不吃坏肚子，我在旅行时只喝瓶装水。
  • Pinyin: Wèile bù chī huài dùzi, wǒ zài lǚxíng shí zhǐ hē píngzhuāng shuǐ.
  • English: In order to avoid getting an upset stomach, I only drink bottled water when I travel.
  • Analysis: `为了 (wèile)` means “in order to,” expressing the purpose of the action.

• `吃坏肚子 (chī huài dùzi)` vs. `肚子疼 (dùzi téng)`: This is the most common point of confusion for learners.
  • `肚子疼 (dùzi téng)` just means “stomach ache.” The cause is unknown. It could be from stress, cramps, or any other illness.
  • `吃坏肚子 (chī huài dùzi)` specifically means your stomach hurts because you ate something bad. It implies a cause. If you have a stomach ache but you haven't eaten anything unusual, you should just say `我肚子疼 (Wǒ dùzi téng)`.
• Not Always Severe: While it can translate to “food poisoning,” `吃坏肚子` often describes milder cases, like indigestion or diarrhea, that might only last a day. Don't assume it always means a severe, hospital-worthy illness.
• Incorrect Usage Example:
  • Incorrect: 我昨天晚上没吃饭，所以今天我吃坏肚子了。(Wǒ zuótiān wǎnshang méi chīfàn, suǒyǐ jīntiān wǒ chī huài dùzi le.) → “I didn't eat last night, so today I have an upset stomach.”
  • Why it's wrong: The phrase requires the action of “eating” something bad as the cause. If you got a stomach ache from not eating, you would simply say `我肚子疼 (wǒ dùzi téng)` or `我肚子饿得疼 (wǒ dùzi è de téng)` (I'm so hungry my stomach hurts).

• 上吐下泻 (shàng tù xià xiè) - To vomit and have diarrhea. A vivid four-character idiom (chengyu) describing the worst symptoms of being sick from food. Literally “up vomit, down diarrhea.”
