Hi. Thanks for your query. The picture is very clear. As the X-ray is showing constipation, the Doctor must be meaning fecoliths. Fecoliths are the hard fecal matter and thereby get stuck in the large bowel. The gases get stuck and give a back-pressure to cause distension of the intestines ( abdomen). Another effect is the large intestine produces too much mucus and pour liquid in effect to facilitate passage and in turn will appear as a IBS type of diarrhea, which you feel like. The simple and best treatment in such cases is a soap-water enema of a conventional type. This allows to passage of the fecoliths out and this will cure your problem. If the condition recurs, a diagnostic colonoscopy in required to rule out a tumor or stricture.
