Advice on managing IBS symptoms

[Emeraldtiger1]

Hi, I have been diagnosed with IBS. My main symptom is constipation, which builds up no matter what I eat or drink and is accompanied by severe bloating and flatulence to the point where (especially in the evenings) I cannot be around people. I almost constantly feel as though I need the toilet but often am unable to go or can only pass small hard stools. When I do go to the toilet it is often urgent and I still feel as though I have not emptied my bowels properly.

I have tried different diets (low fodmap, dairy free, gluten free, increasing fibre) but none have made any difference. I have tried various laxatives. Several (including laxido, fybogel, and lactulose) have made my stool softer but I still could not empty my bowels properly and would have to go urgently several times throughout the day (to the point where I could not leave the house). Dulcolax did empty my bowels but I also had the worst cramps ever so cannot take it again. Senna had no effect.

Does anyone have any suggestions for other things I can try or has been experiencing similar symptoms?
