What happens at your GP appointment

Treatment for rickets and osteomalacia

Rickets and osteomalacia are usually caused by low levels of vitamin D and calcium in your body. Our bodies make vitamin D when our skin is exposed to summer sunlight. But we cannot make enough vitamin D from sunlight between September and March, which can cause low vitamin D levels. Calcium is found in milk, cheese, yoghurt and green leafy vegetables, as well as other foods. You may not get enough if you do not have a healthy, balanced diet. Treatments for rickets include: taking vitamin D and calcium supplements having a healthy, balanced diet spending more time outside with the sun on your skin, which is a good way to increase your vitamin D levels naturally Information: Spend time in the shade when the sun is at its strongest. In the UK, this is between 11am and 3pm from late March to September. If rickets or osteomalacia have caused problems with your bones, such as bowed legs, you may need further treatment to fix this. Some people may need surgery. If your rickets or osteomalacia symptoms are caused by another condition, treating that condition will help.
