〔健康頻道/綜合報導〕「以前很少泌尿道感染,更年期後卻三不五時就中獎?」營養師邱世昕說明,女性停經後雌激素下降,陰道及尿道周邊黏膜變薄,局部保護性菌叢也會跟著改變,以致感染風險上升。研究指出,若有反覆感染問題,規律攝取蔓越莓萃取物膠囊、全果粉等,復發風險可降約26%。不過,研究中有效劑量約每日36毫克PAC以上,並非喝杯市售蔓越莓汁就有用。此外,他也提醒,不能以此取代急性感染時的正規治療。
雌激素下降生理結構改變
邱世昕於臉書粉專發文指出,雌激素除與骨質、心血管健康有關,對泌尿生殖道黏膜及局部菌叢平衡也扮演重要角色。停經後雌激素下降,對於陰道、尿道周邊黏膜、局部保護性菌叢等,均會有所影響。因此,泌尿道感染風險較停經前增加並非運氣差,而是生理結構改變所致。

想要保護泌尿道,飲食或保健品部分,蔓越莓是討論度最高的選項之一。邱世昕指出,一篇針對反覆泌尿道感染的健康女性統合分析發現,規律攝取蔓越莓相關產品,如萃取物膠囊、全果粉等,可使復發性泌尿道感染風險降低約26%。另,2025年1項隨機對照試驗,讓有反覆感染病史的女性每天補充500毫克全蔓越莓果粉,結果顯示,培養確診的泌尿道感染發生率,較安慰劑組明顯降低。
喝市售蔓越莓汁效果恐打折
不過,不是隨便買瓶蔓越莓汁喝,就能達到效果。邱世昕表示,市售蔓越莓綜合果汁可能有額外加糖、有效成分濃度被稀釋、未清楚標示原花青素(PAC)含量等問題;研究中使用的多為標準化萃取物或全果粉,也因此有些人天天喝蔓越莓汁仍反覆感染,因為蔓越莓汁並非研究驗證過的種類。
原花青素含量是關鍵之一
此外,邱世昕提醒,挑選蔓越莓產品時,應特別注意PAC含量。研究裡看到明確效果的劑量範圍,大約落在每日36毫克PAC以上(相關試驗使用範圍約36-72毫克/天),購買前務必翻到背面成分標示,查看「原花青素」或「PAC」標示與數字。若只寫「蔓越莓萃取物○○毫克」,卻沒有標示PAC純度,很難經由萃取物總重量推估實際有效成分。
急症須就醫 2類人須當心
邱世昕總結,更年期後反覆泌尿道感染困擾者、停經前也容易復發性感染的女性,均為合適優先補充者,但若已出現感染症狀,如灼熱感、頻尿、發燒,仍應儘快就醫評估是否需要抗生素治療,不能只靠蔓越莓硬撐。此外,服用抗凝血藥物如warfarin、有腎結石病史者,補充前務必要先詢問醫師是否適合。
