Rickets causes a child's bones to become soft and weak, which can lead to bone deformities.
The signs and symptoms of rickets can include:
Some children with rickets may also have low levels of calcium in their blood (hypocalcaemia). This can make the symptoms of rickets worse and can also cause muscle cramps, twitching, tingling in the hands and feet, and fits.
Adults can experience similar symptoms such as bone pain, muscle weakness and fragile bones that are more prone to fractures. In adults, these symptoms are known as osteomalacia.
Visit Arthritis Research UK to find out more about symptoms of osteomalacia.
If your child has any signs or symptoms of rickets, such as bone pain, delayed growth, muscle weakness or skeletal problems, take them to your GP for a check-up.
If you are an adult and you're experiencing bone pain or muscle weakness see your GP to get it checked out.
