Question

Osteomalacia in adults is due to the deficiency of vitamin:
A) A
B) D
C) E
D) K

Answer 1

Hint: We know that Osteomalacia is a disease that is characterized by the softening of the bones. It is caused by metabolism of impaired bone mainly because of insufficient levels of available phosphate, calcium, and vitamin, (or) due to resorption of calcium.

Complete step by step answer:
We must remember that the common cause of Osteomalacia is a deficiency of vitamin D, which is generally obtained from exposure to sunlight and, to a lesser extent, from the diet. In children, Osteomalacia is called rickets. Diffuse body pains, weakness of muscle, bones fragility are some of symptoms and signs of Osteomalacia. Inadequate bone mineralization is caused by the impairment of bone metabolism. Easy fracturing, bones bending, flattening of pelvic, walking difficulty, compressed vertebrae are other symptoms and signs. Cadmium poisoning, chronic kidney failure, malnutrition during pregnancy causes Osteomalacia. We can prevent and treat Osteomalacia by taking supplements of calcium and Vitamin D.
Therefore, the option (B) is correct.
The lack of vitamin A causes night blindness. The lack of vitamin A in blood and tissues are Vitamin A deficiency (VAD) (or) hypovitaminosis A. Retinols, beta-carotenes, and provitamin A carotenoids are three forms of vitamin A.
Therefore, the option (A) is incorrect.
The deficiency of Vitamin E causes impaired reflexes, weak muscles, and walking difficulties. Premature infants with this deficiency could develop a major form of anemia.
Therefore, the option (C) is incorrect.
The deficiency of Vitamin K is seen rarely in adults and commonly in infants. The condition of deficiency of vitamin K in infants is called vitamin K deficiency bleeding (VKDB).
Therefore, the option (D) is incorrect

Therefore, the option B is correct.

Note:
We have to know that Vitamins A, D, E, and K are known as the fat-soluble vitamins, due to their solubility in organic solvents. They are absorbed and transported in a similar way to that of fats.
