Fingers, wrist, elbow, knee, ankle, thumbs or foot, gout can affect any of part of the body. But, in majority of cases, the most commonly affected joint is the big toe. Many may wonder why? The reason attributed is that the big toe is the farthest part of the body; the blood is cooler around this joint and has a high tendency for deposit of uric acid crystals. Numerous studies indicate that there is a high possibility for gout to affect the cooler extremities most often.
Know the connection between Gout and high uric acid in the blood. Understand gout symptoms, the causes and diagnosis procedures. Check out why following gout diet help find relief from gout pain and keep gout attacks at bay.
Gout and high uric acid
A higher-than normal level of uric acid in the blood is the contributing factor for gout. Uric acid (urate) is a substance that gets created when the body breaks down substances called purines. Purines are nitrogen-containing compounds which are made by the body inside the cells or are found in foods and drinks that are consumed.
If the body makes higher than normal uric acid or if the kidneys have a tough time getting rid of uric acid from the body, it leads to accumulation of uric acid. When the level of uric acid builds up in the body, it leads to a condition called hyperuricemia. As such the condition is not serious.
Not all those with hyperuricemia develop gout. But it can be understood as an indication and the chances are high for developing gout. If the elevated levels of uric acid results in painful arthritic attacks due to buildup of uric acid crystals in and around the joints, it is gout. The pain, joint inflammation is due to white blood cells engulfing the uric acid crystals.
The first fiery gout attack will usually be in the night sans any warning. It could be the big toe or around any joint and may last for five to ten days. It can be a combination of sudden burning pain, stiffness and swelling. The next attack may not happen for months or even years.
The discomfort and pain is likely to be most severe within the first 12 to 24 hours. Even after the pain subsides, a lingering discomfort may last for few more days. Typical gout symptoms include:
Though the relationship between gout and uric acid crystal formation is well understood, the exact cause for gout is still unknown. There are many circumstances that can lead to increase in uric acid formation.
If the symptoms of gout are consistent, it can be understood as the onset of gout. Early, prompt diagnosis will help decide treatment plan. Also, if left untreated, gout may result in increased pain and damage the joints. Those diagnosed with gout are at risk for cardiovascular disease. Hence, it is best to seek an immediate appointment with a health care provider.
The doctor will conduct a physical examination of the musculoskeletal system; with specific focus on commonly affected joints. And may ask questions related to family medical history. At this point, it is essential to disclose prescription and non prescription medications being taken, if any. Intake of medicines can change or affect test results that may be required to diagnose gout.
As gout can easily mimic the symptoms of medical conditions such as pseudogout, psoriatic arthritis, rheumatoid arthritis or an infection, tests such as serum acid test, synovial fluid test and an x-ray will be required to confirm diagnosis of gout and/or rule out other medical conditions.
Close to confirming test date, the doctor will explain how consumption of certain foods that are high in purine may increase levels of uric acid. These include kidneys, liver, sweetbreads, sardines, anchovies, and meat extracts.
Serum uric acid test
This test measures the amount of uric acid in blood. A blood sample from the vein, preferably the vein in the arm is required. It is usually done four to six weeks after a gout attack. The age, gender, health history are given due considerations while examining the results of the test. The results are considered normal if the test result for adult male is 2.5-8 mg/dL (150-480 micromol/L) (3) and for adult female is 1.5-6 mg/dL (90-360 micromol/L (3). This may vary from one laboratory to another.
However, the doctor will explain the results and confirm prevalence of gout depending on the levels of uric acid in the blood. Serum uric acid test is not considered the most definitive way to diagnose gout. Hence, the next test would be to take a sample of fluid from the affected joint and test it for urate crystals.
Synovial fluid analysis
Synovial fluid is the fluid around the joints that allow lubrication of the joints. Synovial fluid analysis includes a group of tests performed to rule out septic arthritis, to understand inflammatory response, infection and to identify monosodium urate or calcium pyrophosphate dehydrate crystals in aspirated synovial joint fluid. With regard to diagnosis of gout, the tests will prove helpful to examine chalky, sodium urate deposits (tophi) around the joints.
In most cases, local anesthesia is administered before collecting sample. The entire procedure is completed in less than a minute. The collected fluid is analyzed for volume, color and clarity and the amount of glucose, uric acid or total protein. Abnormal joint fluid may look cloudy or abnormally thick. But, laboratory test results may vary depending on age, gender, health history, the method used for the test, and many other factors. For uric acid levels rise and fall depending on many complex factors in the body.
X-ray: An x-ray will not help diagnose gout. The primary purpose of taking an x-ray is to rule out other medical conditions which cause the pain and related discomfort and to monitor the effects of inflammation and pain on joints.
Gout diagnosis confirmation
The tests will be followed by a detailed analysis aimed at understanding the pattern of pain and associated symptoms of gout. If majority of patterns prevail, it confirms onset of gout.
When the body responds to the presence of uric acid crystals with a sudden inflammatory reaction, it is termed as gout attack.Most of the time, gout attacks happen at night. The pain, described best as burning pain, can be very intense and so bad that the joints can't even stand the slightest touch. Walking or standing may become difficult and almost impossible.
Gout attack can occur suddenly for no apparent reason. The attack can happen in the same join again and again. Mild gout attack may last for a day or two and then the symptoms will diminish. Severe attacks may last up to several weeks. Subsequent to an attack, the next one is most likely to occur within 6 months to 2 years. There are also instances where there has never been another gout attack after the first/initial attack.
Gout cannot be cured but can be treated successfully. Gout attack symptoms are often relieved within 24 hours after treatment has begun. A good gout treatment plan will target the immediate need, address long-term management of gout attacks and prevent development of further complications. Stopping the pain and providing relief from pain and inflammation associated with gout attacks would be the priority, besides containing gout attacks. All the while concentrating on reducing the amount of urate in blood.
Medications: Anti-inflammatory medications and pain relievers are prescribed for gout pain relief. NSAIDs (non-steroidal anti-inflammatory drugs) (Examples: indomethacin and naproxen), Colchicines, Steroids (Example: prednisone) are effective in getting relief from pain, reduce inflammation, reduce and prolong frequency of gout attacks.
Also, doctors recommend a high liquid intake to facilitate increase in daily urine output. Medicines that lower the level of uric acid in the blood will be prescribed (Example: allopurinol or probenecid.). These are recommended for those who have had multiple attacks of gout or kidney stones due to high levels of uric acid. A prescription for lifestyle changes will be provided. It includes:
The role of a healthy dietary regimen cannot be overlooked. Need for dietary restrictions are reduced and taken care of with medications. Gout diet plays a vital role in decreasing the severity or frequency of gout attacks. A gout diet is agout friendly diet with particular reference to avoiding foods that are high in purines, which help control body's production of uric acid.
