👨‍⚕️ Dr. BOSS 的聊天室｜Episode 23：乳糖不耐症的人一定腹瀉？ BOSS Doctor’s Chatroom｜Episode 23: Do People with Lactose Intolerance Always Get Diarrhea? 副標 / Subtitle 👨‍⚕️ Dr. BOSS × 🐨 Koala | 腸道小迷思：乳糖不耐症不等於每次都拉肚子 👨‍⚕️ Dr. BOSS × 🐨 Koala | Gut Myth: Lactose Intolerance Doesn’t Always Cause Diarrhea --- 🟦 對話稿 Dialogue（中英對照） Koala： BOSS醫生，我聽說乳糖不耐症的人喝牛奶一定會拉肚子，是真的嗎？ Doctor BOSS, I heard that people with lactose intolerance always get diarrhea when they drink milk. Is that true? BOSS 醫生： 不完全正確。乳糖不耐症是因為體內乳糖酶不足，無法完全分解乳糖。但症狀有輕有重，有些人只會腹脹、放屁，甚至沒有明顯症狀。 Not entirely. Lactose intolerance occurs when the body lacks enough lactase to break down lactose. Symptoms vary—some people get bloating or gas, and some may have no obvious symptoms. Koala： 那腹瀉是怎麼發生的呢？ How does diarrhea occur then? BOSS 醫生： 未分解的乳糖會在腸道吸水，並被細菌分解產氣，可能引起腹瀉、腹脹和放屁。嚴重程度因人而異。 Undigested lactose draws water into the intestines and is fermented by gut bacteria, producing gas, bloating, and sometimes diarrhea. Severity varies by individual. --- 🟦 結構篇 Structure（中英對照） BOSS 醫生： 乳糖不耐症的症狀主要取決於乳糖酶活性和攝取量： Symptoms of lactose intolerance depend on lactase activity and lactose intake: 1. 輕度 Mild 中文：少量乳製品可能只會輕微腹脹或放屁 English: Small amounts of dairy may only cause mild bloating or gas 2. 中度 Moderate 中文：腹脹、放屁、偶爾腹瀉 English: Bloating, gas, occasional diarrhea 3. 重度 Severe 中文：大量乳製品可能引起明顯腹瀉、腹痛 English: Large intake may cause significant diarrhea and abdominal pain --- 🟦 日常使用 Daily Use（中英對照） Koala： 乳糖不耐症的人平時該怎麼飲食呢？ How should people with lactose intolerance manage their diet? BOSS 醫生： 選擇低乳糖或無乳糖產品，逐步增加乳製品耐受量，並搭配益生菌可改善腸道反應。 Choose low-lactose or lactose-free products, gradually increase tolerance, and probiotics can help gut response. 舉例 Examples: 低乳糖牛奶 Lactose-reduced milk 優格 Yogurt (含活性菌) with active cultures 奶酪 Cheese (通常乳糖低) 酶補充 Lactase enzyme supplements --- 🟦 小知識 Mini Note（中英對照） Koala： 那乳糖不耐症的人一定要完全避免乳製品嗎？ Do people with lactose intolerance have to avoid all dairy? BOSS 醫生： 不一定。症狀輕的人可以適量攝取乳製品，分次少量或選擇低乳糖產品，多數人能安全享用。 Not necessarily. People with mild symptoms can consume dairy in moderation, in small portions or choose low-lactose products, and most can safely enjoy them.
