Gout is a condition that causes sudden and severe attacks of pain, redness and swelling of joints. Gout is a condition has been well known for many centuries. Most often it affects a single joint in one episode, often the big toe. About 9 out of 10 affected individuals affected by gout are men over the age of 40. The peak age of attacks is 75 years, but it can occur in young individuals on rare occasions. Over one millions Americans have a gout attack each year.
Gout is due to accumulations of uric acid within the fluid of your joints. Uric acid is a waste product of many foods that we eat. In order to properly digest food, and rid our body of waste, we produce substances such as uric acid to transport waste material. Ultimately, uric acid is excreted via the kidneys in urine. However, when the transportation of uric acid is impaired, and uric acid accumulates in the blood stream, the condition called gout may result.
The impairment of uric acid excretion is often due to a hereditary problem, but can also have other causes. When the uric acid level becomes too high for an individual, painful attacks of gouty arthritis, or joint pain, can result. Other symptoms can include kidney stones, and, ultimately, kidney failure. It is interesting to note that the relationship between uric acid levels in the blood stream and gout is unclear. Some individuals with gout have normal or near normal blood levels of uric acid; other individuals have very high blood levels of uric acid with no symptoms of gout. It appears to be entirely dependent on the individual.
As stated previously, some individuals have a hereditary condition making them more susceptible to gout; other risk factors also contribute to having a gouty attack. Among these are obesity and sudden weight gain, abnormal kidney function, excessive intake of alcohol (especially “binge” drinking), and certain types of cancer. Some medications, such as thiazide diuretics to control blood pressure, and foods that are rich in purines can lead to attacks. Purine-rich foods include organ meats (e.g. liver, kidney), herring, anchovies, and to an extent, all meat products.
Most often the diagnosis of gout can be made by a description of the symptoms and medical history. Your doctor will want to know about risk factors that may be contributing to the onset of this attack. This may be sufficient to make a diagnosis of gout, especially if you have had a gouty attack before.
The diagnosis can be confirmed through sampling the joint fluid by inserting a small needle into the affected joint; this procedure is performed under local anaesthetic. Under the microscope, joint fluid from an affected joint will be full of tiny uric acid crystals that look like small needles. Blood tests may also be performed to check for uric acid levels (however, as stated above, these need not be elevated in gout, but often are), and kidney tests may be done to check your kidney function.
Acute gout attacks are characterized by a rapid onset of pain in the affected joint followed by warmth, swelling, reddish discoloration, and marked tenderness. Tenderness can be intense so that even a blanket touching the skin over the affected joint can be unbearable. Patients can develop fever with the acute gout attacks. These painful attacks usually subside in hours to days, with or without medication. In rare instances, an attack can last for weeks. Most patients with gout will experience repeated attacks of arthritis over the years.
Uric acid crystals can deposit in tiny fluid-filled sacs (bursae) around the joints. These urate crystals can incite inflammation in the bursae, leading to pain and swelling around the joints (a condition called bursitis). In rare instances, gout leads to a more chronic type of joint inflammation that mimics rheumatoid arthritis.
One of the best treatments is rest. This will help reduce swelling and decrease the pain by settling the symptoms. Icing for 20 minutes a day is also recommended. Corticosteroids are considered to be very effective in treating gout in the knee. In addition, Colchicine medicine is recommended by most physicians for curing gout as it reduces the buildup of urate. Lastly, NSAID’s (over the counter medication) have also proved to be effective when taken at earlier stages of gout development.
