E) Pellagra

Question

Quizplus · Accepted Answer

Osteomalacia is a condition where bones become soft due to a decrease in mineralization of the bone matrix. This can be due to a variety of causes, such as vitamin D deficiency, renal failure, or malabsorption. Osteoporosis, on the other hand, is a condition where there is a decrease in bone mass and density, leading to an increased risk of fractures. Osteopetrosis is a rare genetic disorder characterized by increased bone density but brittle bones, while osteitis deformans is a condition where there is abnormal bone remodeling leading to bone deformities. Pellagra is a nutritional deficiency disease caused by a deficiency in niacin.
