All about gout
Gout is a specific type of inflammatory arthritis characterized by sudden, intense pain in the joints. In this article, a consultant rheumatologist, Professor Hasan Tahir, explains the causes, symptoms, diagnosis, and treatment options for gout
What causes gout?
Gout occurs when there is an excess uric acid in the blood, a condition called hyperuricemia. Uric acid is a waste product created when our bodies break down certain foods and drinks containing substances called purines. Normally, uric acid dissolves in the blood and is eliminated through urine. However, when there's too much uric acid, it can form sharp, needle-like crystals that accumulate in joints, causing inflammation and pain.
Several factors can increase your risk of developing gout:
- Gender: Men are more likely to develop gout than women, especially before menopause.
- Medical conditions: Obesity, diabetes, high blood pressure, and kidney diseases can increase your risk.
- Family history and genetics: If gout runs in your family, you may be more susceptible due to genetic factors.
- Diet: Consuming foods high in purines (like red meat and shellfish) or fructose (found in sugary drinks and foods) can contribute to gout.
- Alcohol consumption: Regular alcohol intake, especially beer and spirits, can raise uric acid levels.
- Medications: Certain medications, such as diuretics, can increase the risk of gout.
What are the symptoms of gout?
Gout typically affects joints in the lower body, with the big toe being the most common site. The big toe is often affected because it's the coolest part of the body, where uric acid is more likely to crystallize. However, gout can occur in any joint, including knees, ankles, hands, wrists, and elbows.
During a gout attack or flare, you may experience:
- Sudden, severe joint pain
- Swelling and redness around the affected joint
- Warmth and tenderness in the area
- Stiffness and limited range of motion
These symptoms can last for several days to a week or more. Gout flares can be triggered by certain foods, stress, illness, or changes in medication.
How is gout diagnosed?
To diagnose gout, your doctor will:
- Perform a physical examination
- Review your symptoms and medical history
- May order blood tests to check uric acid levels
- Possibly take a sample of joint fluid to look for uric acid crystals
- Sometimes recommend imaging tests (X-ray, ultrasound, or MRI) to assess joint damage
How is gout treated?
Gout treatment focuses on managing symptoms, preventing future attacks, and lowering uric acid levels long-term. Your doctor may recommend:
- Pain relief medications:
- Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen
- Colchicine, a specific medication for gout flares
- Corticosteroids, either as pills or injections, to reduce inflammation
- Uric acid-lowering medications:
- Allopurinol, which reduces uric acid production
- Febuxostat, a newer medication that also lowers uric acid levels
It's important to note that these medications may have side effects, which your doctor will discuss with you.
- Lifestyle changes:
- Maintain a healthy weight
- Stay hydrated
- Limit alcohol consumption
- Reduce intake of high-purine foods (red meat, organ meats, shellfish)
- Avoid sugary drinks and foods high in fructose
- Incorporate foods that may help, such as cherries, vitamin C-rich fruits, whole grains, and low-fat dairy products
Long-term management and complications
Proper long-term management of uric acid levels is crucial to prevent joint damage and other complications. Untreated gout can lead to joint destruction and the formation of tophi (deposits of uric acid crystals under the skin).
Regular follow-ups with your healthcare provider are essential for monitoring uric acid levels and adjusting treatment as needed.
Seek immediate medical care if you experience:
- Severe, debilitating pain
- Fever along with joint symptom
