Our bodies use calcium and phosphate to build strong bones. Osteomalacia may occur if our bodies don't absorb these minerals properly, or if we don't get enough of them in our diet.

These problems can be cause by
- Vitamin D deficiency. Vitamin D deficiency is a common cause of osteomalacia worldwide. Sunlight☀️ produces vitamin D in our skin. Our bodies need vitamin D to process calcium. Osteomalacia can develop in individuals who spend little time in the sunlight or in people who eat a diet low in vitamin D.
- Certain surgeries. The stomach breaks down food to release vitamin D and other minerals that are absorb in your intestine. This process is disrupted if you have a Gastrectomy, or surgery to remove or bypass the small intestine and can lead to osteomalacia.
- Celiac disease. In this autoimmune disorder, the lining of the small intestine is damaged by consuming foods containing gluten, a protein found in wheat, barely and rye. A damaged intestinal lining doesn't absorb nutrients, such as vitamin D, as well as a healthy one does.
- Kidney or Liver disorders. Problems with your liver or kidney can interfere with your ability to process vitamin D.
- Drug. Some drugs used to treat seizures.
