Children with rickets grow up. If rickets is detected early and treated promptly, it usually does not affect the growth of children in later stages, but if rickets develops into skeletal deformities in later stages, it may have an impact on growth, such as a slower growth or a shorter size. Rickets is a systemic disease characterized by skeletal lesions due to vitamin D deficiency in the body, which causes disorders of calcium and phosphorus metabolism. In the early stages of rickets, children will show signs of increased neuroexcitability, such as irritability, irritability, sleep, night cries, sweating, occipital baldness, etc. At this time, it is generally not obvious that it affects bone development, and if treated in a timely manner, it will not affect the growth of children. With the development of the disease, skeletal changes and delayed development of motor functions may appear during the active period, such as square skull, chicken chest, funnel chest, “O” or “X” shaped lower limb deformities. If the treatment is not timely and the disease develops seriously, the child with rickets usually grows slower and is shorter. The clinical treatment of rickets is based on vitamin D supplementation, and different doses of vitamin D are given according to the age of the child. In addition, calcium supplementation is also an important treatment measure. During the treatment period, it is important to take the medication according to the doctor’s prescription on time and in accordance with the dosage, and never stop the medication privately. Meanwhile, in daily life, children with rickets should increase outdoor activities to get enough sunlight to promote recovery. The diet should also be rich in vitamin D foods, such as deep-sea fish, liver, etc.
