I have previously posted on here about my health worries following a DVT over two years ago. Ever since it happened I have been constantly convinced that the DVT was caused by cancer that would eventually start showing itself in other ways............it never has done!! However last year I lost my mum to liver cancer and since then I have been even more stressed and anxious which I believe has contributed to my problems with constipation, not really going to the toilet properly (sorry!), abdominal cramps, backache and sometimes bad heartburn. Can anyone tell me if IBS can be triggered by a very stressful event such as a bereavement, also bearing in mind that I was extremely worried and stressed about my health even before then.
