Welcome to the 'club'. I'm 38 and have had this for the past 4 years. I've had all the tests that you have had, plus ultrasound and stool tests. If you haven't had any stool tests, be sure to ask your doctor to get them--to test for parasites.
Keep a food journal (it's a pain, but worth it) and write down what you eat, when you eat, and then what/how/when the 'results' are. Over a few weeks time, you will find out which foods will 'trigger' it or not.
Some of the 'common' triggers are dairy and 'greasy' food. When I eliminated dairy from my diet, I noticed a big improvement.
Also, in your diary, notate your moods, how your feeling, throughout the day, and every time you have a bathroom moment, in addition to the time you eat.
Your moods can affect your digestive tract. Feelings of anger, pain, stress, anxiety, and so on will/can have an effect.
I suggest not only seeing a GI doctor, but also talking to a counselor--even if you think you're "normal" psychologically. A psychologist can help uncover any hidden guilt/anger/hurt/pain that could be contributing to your gut issues.
A counselor can teach you methods of relaxation and such that will calm your nerves which has positive effects on your GI track!
Depression and stress will make IBS worse--so that's why you need to see both a medical MD as well as a psychiatrist.
If you are religious--whether Christian, Catholic, Jewish, Buddhist, etc....develop meditation, prayer, reflection time, retreats (whatever applies). If you're Christian--talk to your pastor/priest about what you're going through and 'connect' it to the suffering of Jesus on the Cross. That takes time and prayer to get to that point (unless you have a strong walk with the Lord already) but that does help too.View Thread
