ANATOMY

Detailed explanation-1: -The most common cause of rickets is a lack of vitamin D or calcium in a child’s diet. Both are essential for children to develop strong and healthy bones. Sources of vitamin D are: sunlight – your skin produces vitamin D when it’s exposed to the sun, and we get most of our vitamin D this way.

Detailed explanation-2: -A lack of vitamin D or calcium is the most common cause of rickets. Vitamin D largely comes from exposing the skin to sunlight, but it’s also found in some foods, such as oily fish and eggs. Vitamin D is essential for the formation of strong and healthy bones in children.

Detailed explanation-3: -Rickets is the softening and weakening of bones in children, usually because of an extreme and prolonged vitamin D deficiency. Rare inherited problems also can cause rickets. Vitamin D helps your child’s body absorb calcium and phosphorus from food.

Detailed explanation-4: -Without enough vitamin D or calcium, your parathyroid glands compensate by producing too much of their hormone, a condition called hyperparathyroidism. That can lead to bone weakening (osteoporosis) and increased fracture risk.

Detailed explanation-5: -Severe chronic vitamin D deficiency [25(OH)D level less than 15 ng/ml] leads to overt skeletal abnormalities in children that is typically defined as rickets (23, 30–32).
