Paroxysmal Nocturnal Hemoglobinuria

Paroxysmal nocturnal hemoglobinuria is a rare, acquired blood disorder in which red blood cells are destroyed abnormally, releasing hemoglobin that can appear in the urine, especially during the night or early morning. It is a condition that usually requires specialized testing to be confirmed.

Common symptoms: dark-colored urine upon waking, marked fatigue, paleness, difficulty breathing, and, in some cases, episodes of abdominal pain or the formation of clots.

When to see a doctor? It is worth seeking evaluation if you notice very dark urine recurrently, accompanied by unexplained tiredness or other signs of anemia that do not improve.

Which specialist treats it? The hematologist is the one who diagnoses and supports this condition through specific laboratory tests. Professional follow-up makes it possible to monitor the progression of paroxysmal nocturnal hemoglobinuria and address the associated discomfort over time.
