Final answer:
The correct answer is Osteomalacia, it is an adult condition where bones soften due to demineralization, often associated with limited sunlight exposure and seen in women post-pregnancies.
Step-by-step explanation:
The adult condition that involves the softening of bones due to demineralization is known as Osteomalacia. This condition is specifically seen in adults and results from demineralization of bone. It's particularly common in women who have had several pregnancies and have had limited exposure to sunlight. Osteomalacia leads to weakened bones, making them more pliable and susceptible to fractures and deformities.
Unlike osteomalacia, Rickets affects children, leading to improper bone development due to the malabsorption of calcium and the deficiency of vitamin D. The lack of vitamin D impairs the intestinal absorption of calcium and phosphate, essential for bone mineralization. Osteoporosis, on the other hand, is a disorder that causes bones to become weak, brittle, and easily breakable, often due to hormonal changes, diseases, or medications in older adults. Osteoporosis involves an imbalance between bone formation and bone resorption, which can lead to increased bone fragility.
