Bowel

Some people with MS will never experience bowel problems, but constipation and bowel incontinence do affect about half of people with MS at some stage.

Bowel problems can be embarrassing and distressing. But discussing the issue and getting the right support and advice can help.

Some variation in bowel movements is normal - every second day may be your routine, or every few days, or having up to three bowel movements in a day.

My MS nurse and I agreed that it was time I took control. She explained that MS was stopping sections of my bowel from working. She suggested that I could try a bowel management system. It was a lot to get my head around, but it helped that my nurse was very matter of fact and positive about it. Lorraine, diagnosed with MS in 2000
