Living with Myelodysplastic/myeloproliferative disease

A rare group of blood and bone marrow diseases that have features of both low and high blood cell production.

Understanding Myelodysplastic/myeloproliferative disease

Myelodysplastic/myeloproliferative disease is a rare group of blood and bone marrow diseases that affect how the bone marrow makes blood cells.

The bone marrow makes too many white blood cells, with features of two types of disease. The myelodysplastic part leads to too few healthy blood cells. The myeloproliferative part means too many of one or more cell types. The main types are chronic myelomonocytic leukemia, juvenile myelomonocytic leukemia, and atypical chronic myeloid leukemia. Others that don't fit are called unclassifiable.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Fever
  • Tiredness

  • Easy bruising or bleeding
  • Weakness

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
