What It Is

Osteomalacia is a softening of the bones, which is usually the result of not having enough vitamin D or calcium (NHS, 2025; MedlinePlus, 2026). In children, the condition is called rickets. Soft bones tend to be more prone to bowing and breaking than bones that are harder and healthier. Osteomalacia isn't the same as osteoporosis, which is another bone disorder that can lead to broken bones. Osteomalacia results from problems in the process of building bone, while osteoporosis develops from a weakening of bone that was previously built.

The literal meaning of osteomalacia is bone softening (osteo = bone, malacia = softening, in Greek).

The main symptoms are bone pain (in the back, shoulders, ribs, pelvis or legs) and muscle weakness, such as difficulty climbing stairs or getting out of a chair. Other symptoms include changes in the way you walk, tingling, cramping or twitching of the muscles, and breaking bones more easily (NHS, 2025). Treating the condition involves topping up low levels of vitamin D and calcium, as well as treating any underlying condition that might be causing the problem (NHS, 2025).

Osteomalacia Causes

Vitamin D comes mainly from sunlight on the skin and, to a lesser extent, from diet. In the UK, we cannot make enough vitamin D from sunlight between October and early March (NHS, 2020). Older people are at risk of low vitamin D because they may spend less time outdoors (for example if they are housebound or in a care home) and their diet may be reduced (NHS, 2020; MedlinePlus, 2026).

Other causes include (MedlinePlus, 2026)

  • Problems absorbing vitamins and minerals from the gut, for example after weight-loss (gastric bypass) surgery or because of a digestive disease
  • Kidney failure
  • Liver disease
  • Low levels of phosphate in the blood (hypophosphataemia)
  • Certain medicines used to treat seizures
