Rickets
Pronunciation
Definition 1
A condition in children in which bones become soft and deformed because they don’t have enough calcium and phosphorus. It is caused by not having enough vitamin D in the diet or by not getting enough sunlight. In adults, this condition is called osteomalacia. Also called infantile rickets, juvenile rickets, and rachitis. (NCI Dictionary)
Definition 2
Bone softening and weakening usually caused by deficiency or impaired metabolism of vitamin D. Deficiency of calcium, magnesium, or phosphorus may also cause rickets. It predominantly affects children who suffer from severe malnutrition. It manifests with bone pain, fractures, muscle weakness, and skeletal deformities. (NCI Thesaurus)
More information
Rickets causes soft, weak bones in children. It usually occurs when they do not get enough vitamin D, which helps growing bones absorb the minerals calcium and phosphorous. It can also happen when calcium or phosphorus levels are too low.
Your child might not get enough vitamin D if he or she
• Has dark skin
• Spends too little time outside
• Has on sunscreen all the time when out of doors
• Doesn't eat foods containing vitamin D because of lactose intolerance or a strict vegetarian diet
• Is breastfed without receiving vitamin D supplements
• Can't make or use vitamin D because of a medical disorder such as celiac disease
In addition to dietary rickets, children can get an inherited form of the disease. Symptoms include bone pain or tenderness, impaired growth, and deformities of the bones and teeth. Your child's doctor uses lab and imaging tests to make the diagnosis. Treatment is replacing the calcium, phosphorus, or vitamin D that are lacking in the diet. Rickets is rare in the United States.
