Áúrich acid: what é, examination, symptoms and causes

Uric acid is a substance formed by the body after the digestion of proteins, which form a substance called purine, which then give rise to uric acid crystals, which accumulate in the joints causing intense pain.

Usually uric acid does not cause any he alth problems being eliminated by the kidneys, however, when there is a kidney problem, when the person ingests too much protein or when the body produces excess uric acid, it accumulates in the joints, tendons and kidneys, giving rise to Gout Arthritis, also popularly known as Gout, which is a very painful type of arthritis.

Excess uric acid is curable, as its imbalances can be controlled through a balanced diet, increasing water intake and eating a low-calorie, low-protein diet.In addition, a sedentary lifestyle must also be fought, with the regular practice of moderate physical exercise. In some cases, when there are very intense symptoms, the doctor can guide the use of specific remedies.

How to understand the uric acid test

Analysis of uric acid can be done through blood or urine tests, and the reference values ​​are:

Blood Urine
Man 3.4 - 7.0 mg/dL 0, 75 g/day
Woman 2.4 - 6.0 mg/dL 0, 24 g/day

The uric acid test is usually ordered by the doctor to help with the diagnosis, especially when the patient has joint pain or when there is a suspicion of more serious diseases, such as kidney damage or leukemia.

The most common is that the patient's values ​​are above the reference values ​​but there is also low uric acid that is related to congenital diseases such as Wilson's Disease, for example.

High uric acid symptoms

The main symptoms of high uric acid, which mainly affects men, are:

  • Pain and swelling in a joint, especially the big toe, ankle, knee, or fingers;
  • Difficulty moving the affected joint;
  • Redness at the joint site, which may even get hotter than usual;
  • Deformation of the joint due to excessive accumulation of crystals.

It is also common the constant appearance of kidney stones, which cause intense pain in the lower back and difficulty urinating, for example. See more details about the symptoms of high uric acid.

What causes high uric acid

Excessive consumption of protein-rich foods such as red meat, seafood and fish increases the chances of high uric acid, as does excessive consumption of alcoholic beverages, both by increasing urate production and reducing of its elimination, and also the consumption of foods rich in saturated fat that increases the risk of insulin resistance and obesity, which decrease the elimination of urate by the kidneys.

How to treat high uric acid

Treatment for high uric acid should be guided by the general practitioner or rheumatologist, but generally includes the use of uric acid-lowering drugs such as Allopurinol, Probenecid or Sulfinpyrazone, and the use of anti-inflammatory drugs such as Indomethacin or Ibuprofen, to relieve joint pain. Lifestyle changes, especially diet, exercise, and water intake, are also extremely important.

During treatment, it is also very important to follow a uric acid diet, avoiding the consumption of foods rich in purines, such as red meat, fish and seafood, as well as giving preference to natural foods instead of industrialized.

What not to eat

Ideally, the best type of diet for people with excess uric acid is the one that includes only the use of organic foods, containing a small amount of industrialized products.

  • Excess red meat;
  • Seafood, mussels, mackerel, sardines, herring and other fish;
  • Very ripe or very sweet fruit, such as mango, fig, persimmon or pineapple;
  • Excessive goose or chicken;
