Rickets is a childhood bone disorder caused by a deficiency of vitamin D, calcium, or phosphate. This condition leads to soft and weak bones, which can result in deformities such as bowed legs or a curved spine. Rickets is most commonly seen in children who do not get enough sunlight or have a poor diet lacking essential nutrients. The symptoms of rickets may include delayed growth, pain in the bones, and muscle weakness. Treatment typically involves increasing vitamin D and calcium intake through diet, supplements, or exposure to sunlight. Early diagnosis and intervention are crucial to prevent long-term complications.
