Osteomalacia is a condition that causes bone thinning, which is frequently caused by a vitamin D deficiency. Vitamin D aids in the formation of the body's bones, therefore when levels are low, the bones are not as strong as they should be. Muscle weakness, bone discomfort, and a waddling stride are some of the symptoms of osteomalacia. The lower back hips, and legs are particularly vulnerable to pain. The weakening of the bones may make them more susceptible to fracture. Osetomalacia may be induced by a lack of sun exposure or a lack of vitamin D in the diet. Bone metabolic problems, cancers, cardiovascular illnesses, and diabetes are all linked to a lack of 25OHD. Also linked to autoimmune illnesses and mental problems. Vitamin D is one of the most important minerals for human health.
