Thank you for the query.
Such symptoms may be caused by partial intestines obstruction. This is the urgent condition and should be ruled out at first. It can be a result of colon cancer
, abdominal adhesions
, hernia, intestines inflammatory diseases, IBS. You should have full blood work, abdomen X-ray and abdominal ultrasound performed. If you suffer also from blood in stool
, mucus in stool, lost of weight, you should not wait anymore.
If intestines obstruction ruled out, you should have colonoscopy and upper GI endoscopy as such symptoms may be also caused by peptic ulcer
Hope this will help.
