    I do have low blood pressure but it hasn't been tied to my Ibs but very interesting to read this. Maybe I need to look into it more

    Finally, someone else who has the same problem. As well as IBD, I suffered a series of heart attacks a few years back and so keep a close I on my blood pressure so that I can adjust my BP medicines and I started to it dropping after bowel movements a couple of years ago. Have raised the subject with my GP but as with most of my symptoms it was just brushed off with some throw-away remark. I am not a doctor but from the information I have gleaned it would seem that a short term drop in BP is not as serious as longer changes. That does seem very low though and a trip to your local surgery is probably a good idea. Do you also suffer from cramps and/or pains in your legs? If you do, this can be symptomatic of something more serious and may not be attributable to your IBD at all. Hope you get to the bottom of this (no pun intended) but try not to worry; modern medicine may have no answer to our IBD but blood pressure anomalies are well within the capabilities of your average GP.

    Personal BP monitors are generally available from pharmacists and some supermarkets from around £10GB. Also if you are in any doubt as to it's accuracy your GP will calibrate it against their own equipment if you ask.

    Hi, I have IBS C for a while. I also get, approx 3 times a year, episdoes of severe left sided abdominal pain causing me to have to run to the toilet. Before I pass a watery stool I come over all sweaty and feel faint, sometimes I nearly do pass out. All passes once I have opened my bowels. Consultant said I feel faint because of the sudden activity in my bowel causing my BP to lower thus causing me to feel faint. Its very frightening and scary if happens away from home. Does anyone else get this too ?

    Yes me too, in fact I have passed out several times, the most frightening time was abroad I was driving to Paris with my two youngest children in the back, stiopped at services and I had a couple of bowel movements tried to walk back to my car and dropped!!! very very scary, has happened here too I had an ECG all normal, had bloods which each time showed raised white cell count just not sure where the infection or virus was! but I often feel faint after a particularly bad episode of loose or upset bowel motions, I get shivery somtimes and hot at other times, its weird...there is some kind of link in the bowel to heart problems I know this cos my mum has had bowel problems since her late 30's many ops and she has heart disease and needed a bypass which in turn caused twisting of the bowel :( she has an ileostomy now after too many bowel resections she lost her large bowel completely :( that said Ive never seen her so healthy in years since she had the ileostomy, the large bowel was the cause of so much misery to my dear mum..I have a sinking feeling I will end up in the same predicament...

    I thought I might shed some light on this. What you're experiencing is a triggering of the Vagus nerve. It's totally normal to lower your bp when having a difficult bowel movement.

    This is more common with older patients and people with ibs for obvious reasons.
