Osteomalacia is a bone disorder characterized by impaired mineralization of newly formed bone matrix.

The accumulation of unmineralized osteoid tissue leads to bone softening, resulting in a series of clinical symptoms and signs such as bone pain, bone deformities, and fractures.

Osteomalacia is closely related to living environment, nutritional status, and lifestyle habits.

In the past, this condition was commonly seen in infants with poor breastfeeding conditions, multiparous women, and women with prolonged lactation, but such cases are now rare.

Instead, the disease is more prevalent among residents of industrialized cities with limited outdoor activities, insufficient sunlight exposure, and severe environmental pollution.
