Rickets is a disorder that affects the bones, causing them to soften and break easily. It is most common in children.
Rickets can cause delayed growth, pain in the bones of the spine, pelvis and legs, and muscle weakness. It can also cause problems with your child’s teeth, such as cavities and problems with teeth structure.
A lack of vitamin D causes most cases of rickets, but this disorder can also run in families. Vitamin D helps the bones absorb calcium and phosphorus from food. When your child does not get enough vitamin D, his or her bones do not get the necessary nutrients that make bones strong.
Children ages 6 months to 24 months are at the highest risk of rickets because their bones are growing very rapidly during this period. Your child may also be at risk if he or she:
Your doctor will ask about your family health history and your child's health and diet. Your child will need a full physical exam. Blood tests and X-rays of the arms or legs can also help your doctor determine if your child has rickets.
Treatment depends on the type of rickets your child has. Rickets caused by nutritional deficiencies is treated with vitamin D and calcium. Your child’s pain and muscle weakness will probably get better within a few weeks of treatment. If your child has inherited rickets or has an illness causing the problem, you may need to see a doctor who specializes in rickets.
If your child has bone deformities caused by rickets, he or she may need braces or surgery to correct the problem.
Be sure your child gets enough vitamin D and calcium. If you breastfeed your baby, your doctor will prescribe a vitamin supplement that includes vitamin D (because human milk only has a small amount of vitamin D). If your baby gets less than 16 ounces of formula per day, he or she will also need extra vitamin D. If you have an older child who has rickets, offer him or her vitamin-D fortified foods (such as breakfast cereals and orange juice) and foods that are high in calcium (such as milk, cheese, and salad greens). Do not give your child vitamin supplements unless they are recommended by your doctor.
Your doctor can tell you about how much time in the sun is safe for your child. Remember that infants and babies should be protected from direct sunlight.
