Rickets is a condition in which bones become soft and weak due to a lack of vitamin D. Your body uses vitamin D obtained from sunlight and food sources to aid calcium in building strong and healthy bones. If a person is unable to get enough vitamin D through these sources, or if the body is unable to metabolize vitamin D properly, disease can set in.
