Chronic:
Lasting a long time
Cognitive difficulties:
Problems associated with memory, language, thinking, and judgment
Deficiency:
A shortage of something
DNA:
The genetic material that tells a cell how to grow and what its job is
DXA (or DEXA) scan:
An X-ray performed to assess bone strength

Glycolysis:
The process of RBCs converting glucose (sugar) into pyruvate and ATP
Hemoglobin:
A protein that helps RBCs carry the oxygen your body needs
Hemolysis:
The breakdown of RBCs, which leads to the release of hemoglobin and bilirubin into the blood

A type of anemia that is caused by the early breakdown of RBCs in the bloodstream or by the spleen
Iron overload:
An excess of iron in the body

Yellowing of the skin caused by high levels of bilirubin in the body
MRI:
A scan performed to look for iron overload in the liver and heart
Ophthalmologist:
A doctor that specializes in vision issues and eye disease
Osteopenia:
A decrease in bone mass or bone mineral density. In severe cases, it can progress to osteoporosis
Osteoporosis:
A severe form of osteopenia where the density and strength of bones are reduced
PKLR:
The gene for pyruvate kinase
PKR (pyruvate kinase in RBC):
The pyruvate kinase enzyme
Red blood cells (RBCs or erythrocytes):
Cells that carry oxygen throughout the body
Scleral icterus:
Yellowing of the whites of the eyes caused by high levels of bilirubin in the body
Spleen:
An organ that filters blood, helps support the immune system, and removes old or damaged blood cells from the body
Splenectomy:
Surgical removal of the spleen
Splenomegaly:
