Nebulous urine, also known as cloudy urine, refers to the appearance of urine that is unclear or hazy. While this might be concerning, it can be attributed to a variety of factors. Synonyms for nebulous urine include turbid urine, milky urine, and opaque urine. These terms describe the same phenomenon and indicate a lack of transparency in urine, which is typically clear. The cloudiness can be caused by various underlying conditions, such as urinary tract infections, kidney stones, or dehydration. As always, it is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment if nebulous urine persists or is accompanied by other symptoms.
