Question 8: Gout is a type of disorder which leads to : [NEET Re-2022]

Answer & NCERT explanation

Correct answer: B Inflammation of joints due to accumulation of uric acid crystals

Gout is a disorder caused by accumulation of uric acid crystals in joints, leading to inflammation, pain, and swelling. It occurs due to hyperuricemia (high uric acid levels in blood). The crystals deposit in joints, especially the big toe. NCERT describes gout as a metabolic disorder. Options A and C describe osteoporosis, while D describes osteoarthritis where cartilage degenerates.

How NTA Uses This Concept

Gout is an inflammatory joint disease caused by uric acid crystal accumulation, typically affecting the big toe and other joints. Students often confuse gout with other joint disorders like arthritis, assuming it's purely an infection rather than a metabolic disorder. The key distinction is that gout results from purine metabolism breakdown and uric acid crystallization in synovial fluid, not bacterial infection. To answer correctly, remember: gout = uric acid crystals + joint inflammation, usually triggered by high purine diet, dehydration, or genetic factors. NTA tests this concept to assess understanding of metabolic disorders affecting the musculoskeletal system.
