Relating to a type of large, abnormal red blood cell that is often associated with certain types of anemia.
The doctor diagnosed her with a megaloblastic anemia, which is characterized by the presence of megaloblasts in the blood.
Megaloblastic → It is formed from "megalo-" (from Greek "megalos", meaning large) and "blastic" (from Greek "blastos", meaning germ or bud). The term describes cells that are larger than normal due to abnormal development, particularly in the context of blood cells.
Think of 'large' ('megalo-') cells that are 'developing' ('blastic') abnormally — that's what megaloblastic refers to.
