from the lungs and carries carbon dioxide away from the cells
and to the lungs
Hepatic Dysfunction
A dysfunction of, relating to, affecting,
or associated with the liver
Homocysteine
An amino acid C4H9NO2S
that is produced in animal metabolism by the demethylation
of methionine and forms a complex with serine that breaks
up to produce cysteine and homoserine and that appears to
be associated with an increased risk of cardiovascular disease
and osteoporitic hip fracture when occurring at high levels
in the blood
Hypercalcemia
The presence of an excess of calcium
in the blood
Hyperhomocysteinemia
The presence of an excess of homocysteine,
a chemical found in the blood, that is an established independent
risk factor for a wide range of cardiovascular diseases in
both men and women, including coronary heart disease, myocardial
infarction, and stroke
Hypervitaminosis
An abnormal state resulting from excessive
intake of one or more vitamins
I
Inflammatory bowel
disease
Either of two inflammatory diseases
of the bowel: Crohn’s disease and ulcerative colitis
Iron Deficiency
A reduction of total iron body stores
that can result in anemia and altered function of many vital
cells in the body
J
K
L
M
Macrocyctic anemia
An anemia (reduction of the number of red blood cells)
characterized by red blood cells that are larger than normal. Two
common causes include vitamin B12 deficiency or deficiency of folic
acid
Magnesium
A silver-white light malleable
ductile metallic element that occurs abundantly in nature
(as in bones and seeds and in the form of chlorophyll in the
green parts of plants) and is used in metallurgical and chemical
processes, in photography, in signaling, and in the manufacture
of pyrotechnics because of the intense white light it produces
on burning, and in construction especially in the form of
light alloys
Menopause
The natural cessation of menstruation
occurring usually between the ages of 45 and 55 with a mean
in Western cultures of approximately 51 (2): the physiological
period in the life of a woman in which such cessation and

of the kidneys, also called nephropathy
Nitrogen balance
The relationship between the
nitrogen taken into the body, usually as food, and the amount
of nitrogen excreted from the body in urine and feces. A negative
nitrogen balance means that parts of the body, such as muscles,
are breaking down faster than they are replaced. Anabolic
steroids are associated with improved nitrogen balance, provided
there is adequate intake of calories and protein
