Who Gets Iron Deficiency?
For some unknown reason, the number of persons in the United States with kidney stones has been increasing over the past 20 years. White people are more prone to kidney stones than are black people. Although stones occur more frequently in men, the number of women who get kidney stones has been increasing over the past 10 years, causing the ratio to change. Kidney stones strike most people between the ages of 20 and 40. Once a person gets more than one stone, he or she is more likely to develop others.
What Causes Iron Deficiency?
There are several mechanisms that
control human iron metabolism and
safeguard against iron deficiency.
The main regulatory mechanism is
situated in the gastrointestinal
tract. When loss of iron is not
sufficiently compensated by
adequate intake after some time
that is determined by the state of
body iron storage, iron deficiency
Cystinuria and hyuperoxaluria are two other rare inherited metabolic disorders that often cause kidney stones. In cystinuria, the kidneys produce too much of the amino acid cystine. Cystine does not dissolve in urine and can build up to form stones. With hyperoxaluria, the body produces too much of the salt oxalate. When there is more oxalate than can be dissolved in the urine, the crystals settle out and form stones.
If fever and chills accompany any of these symptoms, an infection may be present. In this case, a doctor should be contacted immediately.
