Gout

Gout is an inflammatory form of arthritis. It develops when urate, a substance formed as the body processes purines, builds up and forms crystals inside or around a joint. The immune system reacts to those crystals, producing a rapid inflammatory attack. The big toe is a familiar site, but gout can also involve the ankle, knee or another joint.

An attack may settle, then return after a quiet interval. Without a management plan, repeated inflammation can affect joint movement and allow firm deposits called tophi to form under the skin or around joints.

Gout commonly presents with intense joint pain that begins quickly, often during rest. A hot, red, swollen joint may be tender even when touched lightly. Toe pain is a common presentation, especially when the joint at the base of the big toe is involved; ankle swelling, joint pain and joint swelling can occur too.

Skin over the joint may look stretched or shiny, and movement can become difficult. Fever or feeling unwell can occur with inflammation, but a very painful hot joint with fever needs prompt medical assessment because infection can look similar.

Gout results from urate crystals forming in joint tissues. This can happen when the body makes more urate than the kidneys can remove, or when the kidneys remove less of it. Dehydration, alcohol, some foods and certain medicines may contribute to an attack in a susceptible person, but an attack is not proof that one recent meal caused the condition.

An untreated attack may improve gradually, but the timing and intensity vary. Some people have one episode; others develop recurrent attacks with longer-lasting joint symptoms. Repeated crystal deposits can reduce movement and damage cartilage and bone. Regular follow-up can track urate control and adjust treatment before attacks become a recurring pattern.

Risk is influenced by family history, kidney function, high blood pressure, metabolic conditions, alcohol use, dehydration and medicines that change urate handling. Chronic kidney disease can make urate removal harder. Obesity may also be associated with higher urate levels, although body size is only one part of a person’s health picture.

A clinician considers the attack pattern, examines the joint and reviews medical history and medicines. A blood test can measure urate, but a result taken during an attack does not always settle the diagnosis. Joint aspiration may remove a small amount of joint fluid so it can be checked for urate crystals and infection. Imaging may help when the diagnosis remains uncertain.

During an attack, anti-inflammatory medication may reduce pain and swelling when prescribed safely for you. A clinician may also advise rest, cooling the joint and drinking enough fluid. If attacks recur or urate remains high, long-term urate-lowering treatment may reduce crystal formation; it must be taken according to the prescribed plan and monitored.

A GP consultation can help coordinate diagnosis, medicines and follow-up. Nutrition counselling can identify practical changes without treating food as the sole cause. Joint aspiration may be used for diagnosis or to relieve pressure when a joint contains excess fluid.

Keep a record of attacks, triggers, medicines and recovery. Wear comfortable footwear during foot or ankle symptoms, pace activity and return to movement as swelling settles. Do not stop a prescribed long-term medicine during an attack unless the prescriber tells you to. Seek advice promptly for a new hot swollen joint, particularly if you feel unwell.

Repeated attacks can lead to tophi, reduced joint movement and lasting joint damage. Urate crystals may also contribute to kidney stones or worsen kidney problems. Early diagnosis, safe anti-inflammatory care and a sustained urate plan can reduce the chance of these problems.

Take long-term treatment consistently if it has been prescribed, attend monitoring appointments and drink fluids regularly unless you have been given a fluid restriction. A balanced eating pattern, gradual weight management where appropriate and moderating alcohol may help. Changes should fit your other conditions and medicines, so discuss a realistic plan with a clinician or nutrition counsellor.

Ask for medical review when attacks repeat, diagnosis is uncertain, treatment is difficult to tolerate, or a joint remains swollen between attacks. A GP can begin assessment and arrange referral to an appropriate musculoskeletal or rheumatology service. Bring a list of medicines and a description of when symptoms started.
