Hi Thanks for posting your query on HCM Urine naturally has odour but not usually very strong.Strong urine odour is not always a cause for concern, however, strong and unusual urine odour might mean an underlying medical condition to investigate.some causes of strong urine odour include : dehydration, diet, bacteria infections,uncontrolled diabetes and rare genetic diseases.With all these possible causes, a urinalysis can help to identify the cause. Strong urine odour if caused by an infection can manifest with abdominal pain but blood on toilet paper suggest a problem in the digestive tract which could be caused by an invasive organism like some bacteria or digestive parasites.A stool exam/culture will help here to identify the organism.I suggest you consult your Doctor to investigate you for a probable urinary tract infection associated with a digestive infection. Hope my answer will help you Best regards
