草酸鈣結晶 | Calcium Oxalate Crystal
草酸鈣晶體
腎結石的常見病因包括草酸鈣結晶、體內尿酸水准高和檸檬酸鹽含量低。研究發現,尿草酸的少量减少與草酸鈣結石的形成顯著减少有關;囙此,建議避免食用富含草酸的食物,如黃瓜、青椒、紅菜頭根、菠菜、大豆、巧克力、大黃、爆米花和甘薯。腎結石多累及腎、輸尿管、尿道等部位。更重要的是,腎結石是一種復發性疾病,據報導草酸鈣晶體的終生復發風險高達50%。發生腎結石的草酸鈣是印度報導的最常見的結石。因此,由於腎結石疾病,現在在印度和世界其他地區發現的心臟病的發病率更高。腎結石降低了體內礦物質的含量,减少了骨骼形成的必要元素。與正常人相比,患者檢測到血液中的高血脂水准可能有發生腎結石的傾向。患者建議服用低脂飲食和天然植物纖維及其草藥。中藥與對症治療相結合是一個很好的方法,可以消除所有與腎結石有關的併發症。 (1)
