What condition can result from a deficiency of vitamin D in adults?

• A. Rickets
• B. Osteomalacia
• C. Osteoporosis
• D. Arthritis

Answer: (B)

A deficiency of vitamin D in adults can lead to osteomalacia, which is characterized by the softening and weakening of bones. Vitamin D plays a critical role in calcium absorption and bone metabolism. Without sufficient vitamin D, the body struggles to maintain adequate levels of calcium and phosphate in the blood, which are essential for proper bone mineralization. In adults, this can manifest as osteomalacia, resulting in bone pain, muscle weakness, and an increased risk of fractures.

Rickets is related to vitamin D deficiency but primarily occurs in children, leading to bone deformities. Osteoporosis involves the loss of bone density and is more associated with hormonal changes and aging rather than a direct deficiency of vitamin D alone. Arthritis encompasses a variety of joint-related conditions, which are not primarily a result of vitamin D deficiency. Thus, osteomalacia is the condition specifically linked to a lack of vitamin D in adults.
