Vitamin D deficiency or poor absorption of calcium and phosphorus are some of the causes that may lead to the development of rickets.

The role of vitamin D

For many years, rickets was a very common disease. Today it is rarely diagnosed, mainly thanks to this, that children from the first days of life are recommended to administer vitamin D drops. This vitamin is also included in milk mixtures. However, vitamin D deficiency is not the only possible cause of rickets. Other diseases can also lead to it, associated with malabsorption.

It comes to rickets, when the bones lack calcium during the period of intensive growth of the child. Its level, in turn, depends on vitamin D., which increases the absorption of calcium in the digestive tract. As a result of rickets, bones are deformed, among other things. Mostly infants and young children are exposed to the effects of the disease.


It is believed, że jednym z wielu objawów krzywicy jest nadmierne sweating of the baby's head, which mothers watch while their baby is being fed, a także late fontanel overgrowth whether late teething, constipation, child irritability. Important however, to remember, that the disease cannot be diagnosed on the basis of the symptoms listed alone. First of all, you need to perform laboratory tests, especially studies of calcium and phosphate metabolism, oraz radiological examinations.


Bone deformities that are a symptom of rickets can leave a permanent mark, although the symptoms of rickets disappear frequently, when the child's diet changes, and also extends the time spent outdoors and in the sun, which promotes the synthesis of vitamin D3 in the body. The most common traces of rickets are: varus or lopsided knees (the baby's legs are in the shape of the letter X or O), curvature of the spine, flat feet, a także defects in the structure of the chest or pelvis.


Protection against rickets is provided by taking vitamin D., as well as a proper diet and a regular dose of outdoor exercise. Vitamin D is synthesized in our body under the influence of sunlight. However, in our climate, especially in the period from autumn to spring, when the sun is scarce, you need to take care of its replenishment. Good to remember, that the appropriate dose of vitamin D for a child is determined individually.
