U must go and see a gastroenterologist i.e. a stomach and intestines specialist and get appropriate tests done...blood tests, X rays, CT scan, endoscopies...whatever the specialist thinks would help in diagnosing why exactly are u constipated. IBS which is irritable bowel syndrome, is related to stress, but then it is a diagnosis of exclusion only !! You need a check up by the experts, rather than waiting for the woooooorst to happen. Finally, not only constipation, but also fibre in the diet and all the stool softners that u will try, will ultimately cause a lot of bloatedness. If nothing works while u r awaiting the expert opinion, u can try glycerine suppositories, pretty effective. Conclusion: Go and see a specialist sooner than later. Good luck !
Agree.
