Rickets is a
vitamin deficiency
disease caused by lack of vitamin D. Rickets causes soft
bones because vitamin D is not present to assist in
calcium and
phosphate uptake. Vitamin D is synthesised in the body on exposure to
ultraviolet light and is supplemented in
milk products. Some people who do not get enough sun exposure, milk products or green vegetable
?s may develop the disease although this is rare today. Hereditary rickets is caused by an inherted defect which prevents the
kidney from retaining phosphate. Rickets can also be caused by some other kidney and
liver diseases.
Rickets causes bone pain, slowed growth in children, dental problems, muscle loss and increased risk of fractures. The classic image of advanced rickets sufferers is of bow legs and a deformed chest and skull.
Treatment involves increasing dietary intake of calcium, phosphate and vitamin D.
