[|AI|]  Hello. Thanks for using this forum on Chat Doctor. The interrelationship of menstrual cycle and the symptoms after gall bladder removal has been studied and still research is going on. The explanation lies in the fact that during menstrual cycle two hormones, estrogen and progesterone play important role. Progesterone is known to cause delayed gastric emptying which means food is released more slowly from the stomach. After gall bladder removal surgery, bile content in the stomach increases many folds. The bile content increases further during menstrual cycle from the fact that progesterone delays food release. This combination of delayed emptying and increased gastric bile reflux leads to discomfort in epigastric region along with vomiting. Consult with your doctor for further anti-emetic prescription. Feel free for further queries. Regards.
