Hi. Thanks for your query. Noted your history of never been constipated, have healthy diet, lots of vegetables, salads, fair amount of proteins, have regular normal bowels but decided to have saline enema and has mucus with blood yesterday and no bm today, wants to know whether this is normal. No, this is not at all normal. I would advise you the following: Wait for the next bm and send stool sample for tests. If there is a problem, consult a General Surgeon for proper clinical evaluation, examination signoidoscopy if required later. Take a course of an antibiotic so that the infection can be avoided as colon is full of bacteria.
