揪出孕酮低的原因與癥狀 對癥“下藥”百戰(zhàn)不殆(2)

孕酮低的癥狀表現：

1、孕婦孕酮低，不孕不育是最為明顯的癥狀。

2、部分患者還出現：

甲狀腺功能不全、乳房脹痛、纖維囊性乳房、低血糖、陰道干燥、體重增加、月經周期不規(guī)則、膽囊疾病、月經期間血液凝塊等的表現癥狀。

3、女性缺少孕酮，對身體危害非常大，極易導致流產、造成滑胎的情況出現。

高濃度的孕酮，對增大的女性子宮，還起到鎮(zhèn)靜的作用，維持女性的早期妊娠。孕酮，會導致女性子宮肌纖維變得松弛，降低興奮性。與此同時，還降低妊娠子宮，對宮縮素的敏感度，減少子宮的收縮，有利于受精卵在子宮里，正常發(fā)育生長。孕期孕酮水平不足，最終會導致女性流產的發(fā)生，要多加注意。

孕酮低的原因與癥狀

孕酮低會導致胎停嗎？

從理論上講，卵子與精子結合形成胚胎需要孕酮，因為在生育過程孕酮幫助刺激子宮變化，而且可以增加生殖系統(tǒng)血管和組織血流，然后促進胚胎發(fā)育。如果孕前期孕酮水平大幅下降，可能容易使未在子宮著床穩(wěn)定的胚胎停止發(fā)育。而在胚胎異常（唐氏或其他染色體異常的胚胎）的情況下，胚胎分泌激素會不足，孕酮也會很低。

黃體功能不全可能是流產的一個原因，但沒有很好的指標去診斷黃體功能不全，一次血中孕酮的測定不足以代表整個孕期水平，血中水平未必等于子宮局部水平。而且人體分泌的孕酮代謝很快，抽血后如果不能及時檢查，檢查結果就會有誤差。所以臨床才使用孕酮和HCG聯合檢查的方法，如果只是孕酮低而HCG正常，多半是檢查誤差，應該復查或以HCG結果為主。

因此，在沒有陰道出血、HCG正常的情況下，孕酮低不一定會導致胎停流產。但要是流產后，孕酮肯定是低的，因為身體已經無需激素分泌來支持胚胎發(fā)育了。

據調查，有20％～50％孕酮低的孕婦并沒有出現過流產癥狀，但是孕酮低仍然需要密切觀察。
