Question

Osteomalacia occurs due to the deficiency of
(a) Vitamin A
(b) Vitamin B
(c) Vitamin C
(d) Vitamin D

Answer 1

Hint: Osteomalacia is a vitamin deficiency disease occurring in bones. The vitamin associated with the disease is also known for the calcium absorption for healthy bones and is also called the “sunshine vitamin”

Complete step by step answer:
Osteomalacia is a bone disease where bone demineralization occurs. It occurs due to the improper metabolism of vitamin D and phosphates. The bone demineralization in osteomalacia is due to the deficiency of vitamin D. Osteomalacia is a significant softening of your bones, caused by severe vitamin D deficiency. The softened bones of children and young adults with osteomalacia can lead to bowing during growth, especially in weight-bearing bones of the legs, and also causes brittle bones Osteomalacia in older adults can lead to fractures.

Additional information: Impaired metabolism of vitamin D results in the poor calcium absorption of bones. This results in the degeneration of bone cells. It is also known as “adult rickets”.Osteomalacia means "soft bones." Osteomalacia is a disease that weakens bones and can cause them to break more easily. It is a disorder of decreased mineralization, which results in bone breaking down faster than it can re-form. It is a condition that occurs in adults. Inadequate concentrations of vitamin D may cause rickets in children.
So, the correct answer is ‘Vitamin D’.

Note: Vitamin D is mostly associated with bone diseases. Thus, the vitamin associated with osteomalacia is vitamin D. The inadequate sunlight exposure causes the deficiency of vitamin D and causes osteomalacia i.e. softening of bones.
