Paroxysmal Cold Hemoglobinuria

Paroxysmal cold hemoglobinuria, also called paroxysmal hemoglobinuria due to cold, is a rare disorder in which red blood cells are destroyed after exposure to low temperatures.

Signs that may appear: After contact with cold, dark-colored urine, paleness, fatigue, and, at times, discomfort in the back or abdomen are often observed.

Which specialist treats it? The internist is usually the one who coordinates its workup, evaluating the behavior of the blood and looking for possible associated causes.

Since its episodes can be confused with other problems, with recurrent dark urine or unexplained fatigue it is worth consulting a professional who can carry out a proper evaluation.
