正确说法

• 旅行中如果出现严重腹泻、持续呕吐或高热症状，应立即就医，切勿自行服用来历不明的药物，以免延误病情或造成不必要的风险。(If you experience severe diarrhoea, persistent vomiting, or a high fever whilst travelling, you should seek medical attention immediately and must not take medicines of unknown origin on your own, so as to avoid delaying treatment or creating unnecessary risks.)
• 孕期早期的恶心呕吐通常在十二周前后逐渐减轻，但若呕吐过于剧烈导致无法正常进食，则需及时就医评估是否存在妊娠剧吐的情况。(Nausea and vomiting in early pregnancy typically ease around the twelfth week, but if vomiting is so severe that normal eating is impossible, medical assessment should be sought promptly to determine whether hyperemesis gravidarum is present.)

错误说法

• 将'呕吐'用于比喻表达厌恶，如'看到这种行为真想呕吐' — while this exists in colloquial speech, 呕吐 is primarily a clinical term; for expressing strong disgust figuratively, 恶心 or 令人作呕 are more idiomatic choices
