Rickets is not necessarily linked to formula milk. Rickets is mainly a metabolic bone disease caused by a deficiency of vitamin D in the body, while the main components of formula milk are various nutrients, including trace elements and vitamins. If the formula contains insufficient calcium, it may exacerbate the symptoms of rickets. Therefore, the main requirement is to intake enough vitamin D. National child healthcare guidelines require that children be supplemented with 400 to 800 units of vitamin D daily from two weeks after birth until the age of two. Additionally, it is important to get ample sunlight in daily life and engage in reasonable outdoor activities to promote calcium absorption, which can effectively prevent rickets. The amount of vitamin D and calcium in formula milk cannot meet the growth and developmental needs of children, so additional supplementation is necessary. Thus, there is a certain connection between rickets and formula milk, but it is not inevitable.

Will rickets lead to hunchback when grown up?

Rickets generally does not result in hunchback when one grows up, as rickets is a disease caused by a vitamin D deficiency leading to disturbances in calcium and phosphorus metabolism. If not cured before development is completed, it often leaves sequelae such as square skull, Harrison's groove, beaded ribs, as well as bow legs, knock knees, and pigeon chest. However, hunchback is mainly caused by developmental deformities of the thoracic and lumbar spine, and is not greatly related to a lack of vitamin D. However, it is also important to note that a deficiency in vitamin D can lead to osteoporosis, and if one does not maintain proper posture in daily life, such as bending the back while sitting, standing, or walking and not being able to stand straight, it may eventually lead to pathological curvature of the spine and thoracic vertebrae. Therefore, in daily life, it is still important to be conscious of using one’s lumbar and thoracic spine correctly to avoid developing a hunchback over time.

The difference between rickets and rib flare

Rickets and rib flaring are different; rib flaring can be considered a symptom of rickets. Rickets is caused by a deficiency of vitamin D in infants and children, leading to abnormal metabolism of calcium and phosphorus, which results in incomplete calcification and softening of the bones, thereby causing skeletal deformities. Rickets can be divided into initial, active, recovery, and sequelae stages. During the active stage of rickets, skeletal deformities such as softened skull, "ping pong" head, square skull, rib flaring, pigeon chest, funnel chest, X-shaped legs, and O-shaped legs are prone to occur.

Can rickets be treated?

Rickets is a disorder caused by a deficiency of vitamin D, leading to impaired calcium and phosphorus absorption, which then results in abnormal skeletal development. It is a chronic nutritional disease. Generally, the rickets commonly mentioned is due to nutritional vitamin D deficiency, which is treatable. Typically, encouraging children to engage in appropriate physical activities while supplementing with an adequate level of vitamin D can effectively control the disease, and it can even be cured. However, if there are special circumstances, such as significant liver abnormalities, renal function abnormalities, renal failure, or abnormalities in the thyroid or parathyroid glands, including parathyroid tumors, or congenital hereditary diseases, the treatment needs to be based on the cause in order to effectively control the disease and promote normal calcium and phosphorus metabolism in the body. Congenital hereditary diseases generally make treatment more challenging. Therefore, it is crucial for children with rickets to seek timely medical examination at a hospital. If it is a common case of nutritional vitamin D deficiency, parents should supplement vitamin D promptly according to the doctor's advice for treatment.

What are the symptoms of rickets?

The condition generally referred to as rickets is most commonly nutritional vitamin D deficiency rickets, a type of nutritional disease that is prevalent among infants and young children, particularly very young babies. It primarily manifests as changes in the bones where growth is most rapid and can also affect muscle development and changes in nervous excitability. Initially, especially within the first three months, symptoms in very young infants typically include increased nervous excitability, such as crying easily, excessive head sweating, and as a result of the sweating, frequent head shaking, irritability, restlessness, and noticeable crying and restlessness at night. These symptoms at this stage are not necessarily indicative of typical rickets. As the condition progresses, changes in the skeleton gradually become apparent. In infants under six months with rickets, the changes are mainly in the skull, typically feeling like pressing on a ping-pong ball. After six months of age, the head shape becomes squared or box-like, and the head circumference is larger than normal. Later, the characteristic beading changes of rickets appear, with beaded protrusions above the ribs, followed by the formation of blunt, circular raised areas at the wrists and ankles, referred to as wrist and ankle bracelets. Around the age of one, infants may develop a deformity resembling pigeon chest. As the child begins to stand and walk, the weight bearing on the lower limbs may lead to deformities, such as bowlegs or knock-knees, and sometimes even K-shaped deformities of the legs, and some might develop spinal deformities.

Early symptoms of rickets

Rickets is a bone disease formed due to a deficiency of vitamin D, clinically referred to as rickets. The early clinical symptoms of rickets, which correspond to the early stages of vitamin D deficiency, primarily manifest as autonomic dysfunction, including night terrors, night sweats, and crying. In the early stages of rickets symptoms, parents often believe the cause to be calcium deficiency. Indeed, vitamin D deficiency can also impair calcium absorption, and these are linked reactions. Therefore, parents should pay attention to supplementing vitamin D, especially in areas with insufficient sunlight, ensuring that children receive less than two hours of sunlight exposure per day. During children's growth phases, it is essential to ensure adequate daily intake of vitamin D, with a basic amount of 400 IU being necessary.
