Doctors warn that women who completely cover their skin do not get enough sunlight to produce the vitamin D necessary for bone health. This lack of sun exposure also lowers the level of vitamin D in their breast milk, which means that their children may develop the same vitamin D deficiencies. Lack of calcium and phosphorous, which are needed for bone repair and replacement, can also lead to rickets. Rickets caused by a dietary lack of these minerals is more common in developing countries because dairy products and green vegetables, the best sources of calcium, are not commonly eaten.   As a physician caring for a nursing woman who has chosen to dress in a way that covers her skin but who is concerned about rickets developing in her baby, you might advise her to .
