Symptoms of uric acid.​
irina [24]

Answer:

Elevated uric acid levels lead to a condition known as "Hyperuricemia."

Explanation:

This condition occurs when there is an excessive presence of uric acid in the blood. It can be divided into:

  • Primary hyperuricemia
  • Secondary hyperuricemia

Primary hyperuricemia occurs when the kidneys are not able to eliminate uric acid in an efficient/proper way. This can be due to the consumption of foos that are very high in purines. For example, liver, gravy, alcoholic beverages, and some vegetables such as spinach and asparagus.

Secondary hyperuricemia may occur to several possible reasons. For instance, kidney disease, in which the kidney is not able to eliminate uric acid; chemotherapy, which may lead to the accumulation of uric acids; or medications that increase the level of uric acid in the blood.

Symptoms include:

  • Fever.
  • Extreme and abnormal fatigue.
  • Joint inflammation.
  • Urination problems.
  • Kidney stones.

To prevent this disease and as part of a treatment (along with medications prescribed by a doctor), a patient should opt to consume foods that are low in purine, such as lettuce, tomatoes, cereals, fruits, milk, eggs, amongst others.
