I suffer with IBS-C. Have been suffering for a couple of years with bloating and not being able to go very easily without the help of laxatives. Overload and overflow has been mentioned by the GP.
I am 40 yrs old and female. The doctor said work out what your triggers are and I can honestly 100 % says it's my girly hormones. The reason being that when my period starts, I'm fine. Fine during it. Producing good quality normal bowel movements with no mess (tmi SORRY !!). About a week after the dreaded curse has ended, it's leading up to OV time and 3 weeks of IBS related issues start again. I can't go and get backed up. Mucus from the backend. Wind, bloating but rarely any real pain luckily for me.
The food triggers seems to be brown bread and high fibre foods which lead to very painful bloating and are best avoided.
