Gout is a type of arthritis caused by the accumulation of uric acid crystals in the joints. Uric acid is a waste product of purine, a natural substance made within the body and also found in various foods, such as red meat and shellfish as well as alcohol (beer).
While uric acid is normally excreted through urine, excessive uric acid can still build up over time. When uric acid eventually crystallises in the joints and tissues, it triggers a gout attack – commonly felt in the fingers and toes.
Common signs and symptoms include:
- Intense pain in one or more joints (usually the big toe)
- Swollen, inflamed joint
- Joint feels hot and very tender
- Limited range of joint movement
