Abdominal Pain In Pregnancy

SYMPTOMS AND SIGNS: Continuous lower abdominal pain during pregnancy. Chinese medicine considers that this pain is due to the obstruction of the uterine channel, so it is called Bao Zhu (obstruction of uterus). 

ETIOLOGY AND PATHOLOGY: The major pathogenic reason for abdominal pain during pregnancy is due to the abnormal circulation of Qi and blood, causing the obstruction of uterine channel and pain. The following are the common seen etiological factors that cause the abnormal circulation of Qi and blood. 

(1). Interior cold due to the kidney Yang deficiency will lead to the obstruction of Qi and blood circulation.
