When children suffer from rickets with noticeable cranial protrusions and abnormal skeletal changes, it is crucial to timely supplement based on the specific needs of the child for trace elements like calcium, as well as vitamin D. Supplementation of vitamin D and trace elements such as calcium, combined with daily activities like sun exposure, are advisable. Additionally, integrating diet changes by consuming foods rich in calcium supports calcium and vitamin D absorption. Consequently, the cranial protrusions can gradually alleviate or disappear. As supplementation continues and the child ages, the shape of the skull may also change accordingly. In daily life, it is important to prevent skeletal abnormalities in children due to calcium and vitamin D deficiencies by making timely adjustments. (Note: The use of medications should be under the guidance of a professional doctor.)

Does rickets have a hereditary component?

Rickets, also known as vitamin D deficiency rickets, is primarily a chronic nutritional disease characterized by skeletal lesions, caused by insufficient vitamin D in infants, children, or adolescents, which leads to disturbances in calcium and phosphorus metabolism. The main feature of this disease is the incomplete calcification of the growth plates and bone tissue in the growing long bones, due to the lack of vitamin D causing incomplete calcification of mature bones. This disease is most common in children under two years old. Its causes may be related to insufficient intake of vitamin D or insufficient sunlight exposure, as well as rapid growth. Additionally, other diseases may influence its development. Therefore, this disease is generally not closely related to genetics.

Can rickets be cured?

Rickets is a type of disease caused by a lack of vitamin D, leading to disturbances in calcium and phosphorus metabolism in the body, and resulting in abnormal bone development. The most common form of this disease is nutritional rickets caused by a deficiency of vitamin D. This type of rickets is curable as it is a self-limiting disease. Generally, timely supplementation of vitamin D and calcium, along with sufficient outdoor activities, can lead to recovery after treatment. However, there are some special cases, such as severe liver and kidney diseases, which require addressing the root cause before the symptoms of vitamin D deficiency can be alleviated. Additionally, there are some genetic diseases for which vitamin D supplementation is ineffective, making their treatment more challenging.

How should children with rickets supplement calcium?

Rickets is a nutritional disease caused by a deficiency in vitamin D, leading to disturbances in calcium and phosphorus metabolism in the body, which results in abnormal bone development. It is mainly due to a lack of vitamin D, so the primary treatment is supplementing with vitamin D. Dairy is a reliable source of calcium nutrition for infants, and generally, it is not necessary to supplement calcium for the treatment of rickets; attention should be paid to supplementing with vitamin D according to the severity of the condition, and spending more time in the sun. For children who have started eating complementary foods, or older children, it is generally recommended to fully supplement vitamin D levels, spend more time in the sun during summer, and consume high-protein nutrients. Additionally, eating more vegetables and appropriately supplementing with calcium supplements in the winter is advised. The dosage should be based on the child's internal levels of calcium and phosphorus, with calcium supplementation adjusted accordingly.

Is pillow baldness rickets?

Balding at the back of the head is a common clinical manifestation of rickets, but it does not mean that balding at the back of the head is equivalent to rickets, as there are many causes for this condition. In children with rickets, due to a lack of vitamin D leading to calcium deficiency, their neural excitability increases, which can affect the baby's sleep and cause restless sleep leading to balding at the back of the head. However, children who are in poor nutritional condition might also experience deficiencies in trace elements, such as a lack of zinc or iron, which can also lead to sleep disturbances and balding at the back of the head, indicating that the cause may not necessarily be rickets. Additionally, a small number of children might have an inherent condition of increased neural excitability that affects sleep, leading to balding at the back of the head, which also isn't due to rickets. Therefore, if balding at the back of the head occurs, it is advisable to visit a hospital’s pediatric healthcare department or pediatric outpatient clinic for a consultation and check-up, to actively treat and manage based on the underlying cause.

What are the early symptoms of rickets?

The early symptoms of rickets are mainly due to the inadequate intake of vitamin D in children, leading to disturbances in the body's calcium and phosphorus metabolism. Early signs usually appear around three months of age in infants, characterized by changes in mental state, restless sleep, frequent crying, and excessive sweating. Increased sweating is often accompanied by cradle cap, where circular bald patches appear on the back of the head. In such cases, it is important to include vitamin D-rich foods in the diet and supplement with vitamin D. Continued breastfeeding, engaging in outdoor activities, and exposure to sunlight are recommended to promote the body’s own synthesis of vitamin D. Regular physical examinations are also advised, and if symptoms of rickets occur, an appropriate increase in vitamin D intake may be necessary.
