Osteomalacia is a condition characterized by the softening of bones due to a deficiency of vitamin D, calcium, or phosphate. This leads to weakened bones, making them more susceptible to fractures and deformities. It often results from inadequate dietary intake, malabsorption issues, or certain medical conditions. Symptoms of osteomalacia may include bone pain, muscle weakness, and difficulty walking. Diagnosis typically involves blood tests to check levels of vitamin D and minerals, along with imaging studies like X-rays. Treatment usually focuses on replenishing vitamin D and minerals through diet, supplements, or medications.
