What Could Be Causing Your Urine to Smell Bad?

12. Liver Disease

A musty or sweet smell emanating from your urine could be a red flag signaling liver disease. The liver plays a crucial role in filtering toxins out of the body, and when it's not functioning properly, these toxins can accumulate and affect the smell of your urine. [High ammonia levels, in particular, can cause musty-smelling urine.] This symptom is often accompanied by other signs of liver dysfunction, such as jaundice (yellowing of the skin and eyes), abdominal pain, and fatigue. If you notice a persistent musty or sweet odor in your urine along with other symptoms of liver disease, it's imperative to seek medical attention promptly to assess your liver health.
