小弟這次健檢報告出爐,指說紅血球過高,該怎麼辦,有什麼辦法改善嗎?Update:紅血球過高會有什麼症狀,平常應該注意什麼,如何改善呢?謝謝…紅血球過高會有什麼症狀,平常應該注意什麼,如何改善呢?謝謝… 1 Answer 劉羅鍋1 month ago您好! 血液中的血紅素 (Hb) 過高，紅血球過多，稱為紅血球增多症、男性超標指數為Hb>17.5，女的則為Hb>15.5。 病徵 高血壓、鼻出血、頭痛、出血傾向、瘀血、表淺血管擴張、肝脾擴大、此疾病造成的合併症有心肌梗塞、腦中風、出血。 成因 處於氧氣稀薄的環境如高海拔，或由於氧無法運送至組織如心臟衰竭時，都會造成組織缺氧，造血器官會自動製造大量的紅血球，造成繼發性紅血球增多症、生理性紅血球增多症（Physiologic Polycythemia），則常發生於居住在14,000到17,000呎高地的居民身上。這種人的紅血球數目通常為每立方毫米六到八百萬個，所以即使在空氣稀薄的情況下，他們也能連續不斷工作。另外，亦有真性紅血球增多症，這是造血器官的癌樣變化，造成紅血球的過度生產，病人的白血球和血小板也會過多。真性血紅素增多症的病人，不但血比容會增加，全血體積也會增加，甚至可達正常約兩倍。 治療方法 真性紅血球過多症的治療目標是要減少血液量與血液黏稠度，採用放血的療法，另為了減少骨髓活動，病人需服用骨髓抑制劑及接受放射線治療。續發性紅血球過多症的治療針對缺氧的疾病或狀況、只要去除發生原因則可改善情況、病人同時應多喝水、多活動、坐著時應抬高下肢、及穿著彈性襪。 以上…………..提供您參考! 0
