Stress can sometimes cause IBS symptoms and younger women have female issues which could make things worse. You really need to be examined and evaluated by your doctor or gynecologist to make sure there is no other serious stuff going on. I used to have all the IBS problems before they even had a name for it. Mine is the chronic constipation kind and it has helped to avoid certain foods that trigger episodes and what has worked well for me is taking probiotics, and there are many to choose from these days that you can get from drug stores, grocery stores and health food stores, or on line. Just do a little research.
