Idiopathic pulmonary hemosiderosis
Idiopathic alveolar hypoventilation syndrome
Type of disease: Rare conditions
Idiopathic pulmonary hemosiderosis is a rare disease characterized by repeated episodes of bleeding into the lungs, which can cause anemia. The body is able to remove most of the blood from the lungs, but a large amount of iron is often left behind. Over time, this iron can cause permanent damage to the lungs. Signs and symptoms usually occur after chronic blood loss or blood in the lungs. Symptoms can include coughing, difficulty breathing, and wheezing, resembling pneumonia. Affected individuals who do not have a large amount of pulmonary bleeding can do well, while others with large amounts of bleeding may only live for a few years. The cause of this condition is currently unknown. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
