Thank you for the query.
Such bowel habit change can be caused by stress indeed. However it can be also a symptom of more serious disease like inflammatory bowel disease
, intestines severe inflammation or even colon cancer
Inflammatory bowel disease is more probable if you are around 25. If you are 50 or older, colon cancer should be always ruled out.
It is advisable to have abdominal ultrasound
, full blood work, liver tests, amylase
, urine analysis and stool tests performed.
If no findings, colonoscopy
should be done.
You can also ask your doctor about Rifaximine treatment for severe infection. Many patients find it very effective.
Hope this will help.
