Excessive formation of uric acid crystals in humans leads to ____
A
gout, a painful inflammatory disease that primarily affects the joints
B
a condition called diabetes, where excessive urine formation occurs
C
a condition of insatiable thirst and excessive urine formation
D
osteoarthritis, an inevitable consequence of aging
Explanation: 

Detailed explanation-1: -Gout occurs when urate crystals accumulate in your joint, causing the inflammation and intense pain of a gout attack. Urate crystals can form when you have high levels of uric acid in your blood. Your body produces uric acid when it breaks down purines-substances that are found naturally in your body.

Detailed explanation-2: -If your kidneys don’t filter out enough uric acid, or your body is producing unusually high levels of it, it can build up in the body and turn into microscopic crystals. These crystals usually form in and around the joints, possibly because the temperature in these areas is slightly lower than the rest of the body.

Detailed explanation-3: -Gout is a painful form of arthritis. Extra uric acid in your body creates sharp crystals in the joints, leading to swelling and extreme tenderness. Gout usually starts in the big toe but can affect other joints. Gout is a treatable condition, and the uric acid level can be decreased by medication and lifestyle changes.

Detailed explanation-4: -Gout usually occurs in only one joint at a time. It is often found in the big toe. Along with the big toe, joints that are commonly affected are the lesser toe joints, the ankle, and the knee.

Detailed explanation-5: -Gout is a disorder in which deposits of uric acid crystals accumulate in the joints because of high blood levels of uric acid (hyperuricemia). The accumulations of crystals cause flares (attacks) of painful inflammation in and around joints.
