Rickets is a health condition that affects the bones, primarily in children. It occurs when there is a deficiency of essential nutrients, particularly vitamin D, calcium, or phosphate. These nutrients are crucial for strong bone development, and without them, bones can become soft and weak, leading to deformities and growth issues. The most common symptoms of rickets include delayed growth, pain in the bones, and skeletal deformities such as bowed legs or a curved spine. Treatment typically involves increasing the intake of vitamin D and calcium through diet or supplements, helping to restore bone health and prevent further complications.
