Hyperuricemia

Pathophysiology

Structure

• Uric Acid: A waste product formed from purine metabolism.
• Kidneys?: Responsible for filtering uric acid from the blood and excreting it in urine.
• Joint Tissues: Areas where uric acid can crystallize, leading to pain? and inflammation?.

Blood

• High uric acid levels can result in the formation of crystals in joints, causing inflammation and pain.

Nerve Supply

• The pain associated with gout is due to inflammation in the joints, which affects the nerves in the area, causing discomfort.

Types of Hyperuricemia

1. Primary Hyperuricemia: Caused by genetic? factors affecting uric acid production and excretion.
2. Secondary Hyperuricemia: Results from other medical conditions or medications that increase uric acid levels.

Causes of Hyperuricemia

1. Diet: High intake of purine-rich foods (red meat, seafood).
2. Alcohol Consumption: Especially beer and liquor.
3. Obesity: Increased body tissue turnover leads to more uric acid.
4. Dehydration?: Less fluid intake reduces uric acid excretion.
5. Kidney? Disease: Impaired kidney function affects uric acid elimination.
