Osteomalacia is the softening of bones due to defective bone mineralization, often caused by vitamin D deficiency, leading to bone pain, muscle weakness, and an increased risk of fractures. Rickets is a condition characterized by weakened and deformed bones due to impaired calcium and phosphorus metabolism, primarily resulting from prolonged vitamin D deficiency.
Your doctor may ask these questions to check for this disease:
Most cases of osteomalacia and rickets can be treated with vitamin D and calcium supplements. In severe cases with skeletal deformities, orthopedic interventions such as bracing or surgery may be necessary to correct bone structure and prevent complications.

Q.
Alkaline Phosphatase Low in Women 30-45: Causes & Next Steps
A.
Low alkaline phosphatase in women 30 to 45 is often benign and tied to nutrition gaps such as zinc, magnesium, or vitamin D deficiency, thyroid issues, malabsorption or celiac disease, medication effects, or hormonal shifts, but persistent low levels with bone pain or fractures can indicate osteomalacia or the rare hypophosphatasia. Next steps include repeating the test, reviewing diet and medications, and checking vitamin D, zinc, magnesium, calcium, thyroid levels, and bone health if symptoms are present. There are several factors to consider. See below to understand more.

Q.
Vitamin D for Women 30-45: Hidden Signs & Vital Next Steps
A.
Key hidden signs can include persistent fatigue, frequent infections, muscle or bone aches, mood changes, and hair thinning, with higher risk if you have limited sun exposure, darker skin, obesity, digestive disorders, pregnancy or breastfeeding, vegan diets, or certain medications. Most adults need 600 to 800 IU daily, but the right plan depends on a 25-hydroxyvitamin D blood test where about 20 ng/mL or higher is generally adequate; next steps include optimizing safe sun and diet, considering D3 supplements with medical guidance, and seeking care for persistent pain, weakness, or severe fatigue. There are several factors to consider, and important details that can shape your choices appear below.
