Hello, I was widowed last year and my then occasional ibs has taken over. I get the runs type which only Imodium will settle, and was prescribed buscopan and colefac. It is definitely stress related, and I can take myself off most of the pills if I get constipated or lose those god awful cramps. In the last couple of weeks I have had two episodes of intense dizziness after going to the loo, it soon passes, but is this a common problem? I'm not dizzy at any other time. I have been taking medication for blood pressure and the dosage has barely changed in 30 years, and I get a different feeling if my blood pressure is raised. Anyone else getting this? Suggestions on what t do? Can't get to the doctor for a few days.
