What Causes Foul Urine Smell?


Q: MY urine smells and some times i have a laking problem. What causes this please?


A:   Several conditions can cause foul-smelling urine. One of the most common causes of malodorous urine is a urinary tract infection (UTI). Patients with UTIs typically experience pain with urination, increased frequency of urination, a strong urge to urinate, and may have discolored, bloody-looking or cloudy-looking urine. Gonorrhea infection can also cause urine to smell foul, and patients may notice a thick yellow or greenish penile discharge that occurs separately from urination. Other common causes of foul-smelling urine are dehydration, which causes waste products carried in the urine to become more concentrated; medications, especially antibiotics; and certain foods, particularly asparagus. Be sure to drink at least six 12 oz. glasses of water a day to ensure that you are not dehydrated; also decrease your caffeine and alcohol intake, since these cause dehydration. If you continue to experience these symptoms, consider getting a urinalysis.
