Gout is a type of inflammatory arthritis characterized by the accumulation of uric acid crystals in the joints, resulting in intense pain and swelling. It commonly affects the big toe but can also impact other joints in the body. This condition arises from either the overproduction or under-excretion of uric acid, a waste product formed from the breakdown of purines found in certain foods. Gout can manifest in acute attacks or develop into chronic gouty arthritis if left unmanaged.

Several factors can increase the likelihood of developing gout, including obesity, a diet rich in purines, excessive alcohol consumption, and certain medical conditions such as hypertension and diabetes. Genetics also play a significant role, as individuals with a family history of gout are at higher risk. Medications that affect uric acid levels, such as diuretics, may further contribute to the onset of gout.

Gout manifests as sudden and severe episodes of pain, often described as sharp or throbbing, accompanied by redness, swelling, and warmth in the affected joint. These attacks can last for days to weeks and may recur periodically. Patients often experience discomfort during the night and may develop tophi, which are deposits of crystallized uric acid that can form under the skin in chronic cases.

Gout is primarily caused by hyperuricemia, a condition characterized by elevated levels of uric acid in the blood. This can result from increased production of uric acid, often due to dietary factors such as high consumption of purine-rich foods (e.g., red meat, seafood, alcohol), or decreased excretion due to kidney dysfunction. Genetic predisposition and certain medical conditions, such as hypertension or diabetes, can also contribute to the development of gout.

The diagnosis of gout typically involves a clinical assessment of symptoms, medical history review, and physical examination of the affected joints. A definitive diagnosis is confirmed through joint fluid analysis, where a sample is taken and examined for uric acid crystals under a microscope. Blood tests measuring uric acid levels and imaging studies, such as ultrasound or X-rays, may also assist in diagnosis and evaluating joint damage.

The management of gout typically involves the use of nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain and inflammation during acute attacks. Long-term management may include medications such as allopurinol or febuxostat to lower uric acid levels and prevent future flare-ups. Lifestyle modifications, including dietary changes and increased hydration, are also recommended to help control uric acid levels.

Preventing gout involves lifestyle modifications to manage uric acid levels and reduce the frequency of attacks. This includes maintaining a healthy weight, staying well-hydrated, limiting intake of purine-rich foods like red meat and seafood, and avoiding alcohol and sugary beverages. Regular exercise and adherence to prescribed medications for those diagnosed with gout can also significantly help in minimizing flare-ups.
