I'm not sure if there are any new studies on this, but I think it might be that hormonal changes can also affect your pain threshold levels in your gut. There are also specific hormones that control the activity in your GI tract. So, if your hormones change and you become more sensitive to pain in your gut this could trigger IBS symptoms. However, my understanding is that once you're through menopause you no longer have hormonal fluctuations so you should see a decrease in your symptoms.
