What is a common sign of hematuria?

Hematuria refers to the presence of blood in the urine, and this condition is typically characterized by visible red or brown discoloration of the urine. The presence of blood can be a sign of various underlying medical issues, including urinary tract infections, kidney stones, or trauma. Recognizing hematuria is crucial because it often indicates the need for further medical evaluation to identify and treat the underlying cause.

Chest tightness, shortness of breath, and constipation relate to different medical conditions and do not signify the presence of blood in the urine. Thus, the definitive sign of hematuria is the presence of blood in the urine, making it the correct answer to the question. Understanding this condition and its signs is vital for accurate diagnosis and management in medical practice.
