Urea Acid is the final product of purine metabolism. Dysfunction of purine 
metabolism leads to the excessive secretion of urea acid. In addition, the 
decline of renal function will give rise to lower excretion of urea acid. These 
two above reasons can result in increase of urea acid content in blood, and then 
these urea acid accumulate in the blood and cause Hyperuricemia.
High urea acid content in blood easily leads to deposition of urate in 
joints, which is commonly called Gout. And when there is more and more 
deposition of urate in renal glomerulus and renal tubules, damages to the kidney 
will be caused or aggravated.
The two main causations of Hyperuricemia, namely, are more secretion of urea 
acid and less excretion of urea acid. Referring to the former causation, we can 
peruse a diet change to food low in purine. And according to data, people who 
take too much sea foods are more vulnerable to this disease. So, patients with 
this Hyperuricemia or kidney problems should pay much more attention to intake 
of sea food.
However, starvation causes the body to metabolize its own (purine-rich) 
tissues for energy. Thus, like a high purine diet, starvation increases the 
amount of purine converted to uric acid. Starvation also impairs the ability of 
the kidney to excrete uric acid, due to competition for transport between uric 
acid and ketenes.
In case that the excretion of urea acid is stocked, medicine should be 
adopted immediately to enhance the degradation of deposited urate. Xanthine 
oxidase inhibitors decrease the production of uric acid, by interfering with 
Xanthine oxidase Uricosurics increase the excretion of uric acid, by reducing 
the reabsorption of uric acid once the kidneys have filtered it out of the 
blood.
In addition to Gout, high content of urea acid can also give rise to vascular 
diseases like hypertension, arteriosclerosis and so on. So the taking under 
control of blood pressure is of great important.
