OVERVIEW
Gout is a painful form of arthritis. When your body has extra uric acid, sharp crystals can form in your joints (usually your big toe). Flare-ups of symptoms like pain and swelling come and go in periods called gout attacks. Treatment is usually a combination of symptom management and changing your diet.
What is gout?
Gout is a form of inflammatory arthritis that causes pain and swelling in your joints. Gout happens when there’s a buildup of uric acid in your body.
Gout most commonly affects your big toe joint. But it can affect other joints, including your:
- Knees.
- Ankles.
- Feet.
- Hands and wrists.
- Elbows.
Gout symptoms come and go (recur) in episodes called flares or gout attacks. A healthcare provider will suggest medications and changes to your diet that will lower your uric acid levels and minimize how often you experience gout attacks in the future.

Diagnosis of Gout
Diagnosing gout typically involves a combination of assessing symptoms, medical history, and conducting specific tests. Here are the key steps in the diagnosis:
- Medical History: The healthcare provider will inquire about your symptoms, including the location, intensity, and duration of joint pain, as well as any previous gout attacks.
- Physical Examination: A physical exam will assess the affected joints for swelling, redness, and warmth.
- Joint Fluid Analysis: A definitive diagnosis is often made by analyzing fluid extracted from the affected joint through a procedure called arthrocentesis. This fluid is examined for the presence of uric acid crystals.
- Blood Tests: Blood tests measure uric acid levels. Elevated levels may indicate gout, but some individuals with gout may have normal uric acid levels during an attack.
- Imaging Tests: X-rays may be used to rule out other conditions or assess joint damage. Ultrasound or dual-energy CT scans can also help visualize urate crystals in the joints.
Complications of Gout
Complications from joint pain can arise if the underlying condition is not adequately managed. These complications may include:
