圣保罗官方：奥斯卡被诊断为血管迷走性晕厥，正遵医嘱休息（圣保罗官宣：奥斯卡确诊血管迷走性晕厥，按医嘱休养中）

Providing medical information

I need to keep my response concise while offering general medical information, emphasizing that we don't provide advice or diagnoses since medical matters are sensitive. For instance, vasovagal syncope is fainting caused by a drop in heart rate and blood pressure due to factors like dehydration or stress. Symptoms can include dizziness and nausea. Treatment involves rest and hydration. Also, I could mention that a player is resting and being monitored, but I should avoid speculation about specifics.

要点解读

• 血管迷走性晕厥：一种常见的“反射性”晕厥，因短时心率/血压下降导致脑供血不足，常由脱水、疼痛、情绪/紧张、久站、闷热等诱发；多数为良性，可完全恢复。
• 典型症状：头晕、眼前发黑、恶心、出冷汗、乏力，短暂意识丧失后很快清醒。
• 运动员处置：补液与休息，寻找并避免诱因；按医疗团队评估排除心源性等更严重原因后，逐步恢复训练。若无异常，通常仅短期休息。
• 对球队影响：一般为短期缺阵观察；若复发或伴随异常检查，才会延长恢复周期。
• 关注点：官方称已按医嘱休息属正常流程；后续若有复训/出场节奏更新，俱乐部通常会同步通报。

需要我继续跟进官方伤情更新，或科普下如何预防此类晕厥（补液、热身、识别前驱症状）吗？
