Here’s what you need to
know about gout
What is gout?
Gout is a serious and painful form of arthritis that occurs when there is too much uric acid in the blood, ¹ either because the body makes more than it should, or the kidneys do not remove as much as they should. ² This uric acid can create tiny needle-like crystals that can build up almost anywhere in your body – not just in your bones and joints, but also in your organs (such as the kidney).3, 4, 5
A gout flare occurs when your body reacts to this buildup of uric acid crystals with heat, redness, swelling and pain. Eventually, a flare ends after your body creates a barrier around the crystals to soothe the pain. Although the pain is gone, the crystals are still in your body and can be building up.3, 4, 6, 7
The buildup of uric acid crystals can cause damage to the bones and joints – even if you’re not feeling pain.4, 8, 9 Getting rid of crystal buildup can help prevent future flares and permanent joint damage, making it important to talk to your doctor about your symptoms and ensure your uric acid level is well controlled.10
What causes uric acid
Despite what some might think, diet is not the main cause of uric acid buildup. In fact, only 1/3 of the uric acid in your body comes from what you eat. The other 2/3 is produced by the body and can be caused by factors like genetics.11 This means that changing your diet alone may not be enough to manage your uric acid levels and adequately control your gout.

What is the connection between gout and kidney disease?
The kidneys are responsible for filtering your blood by removing wastes, toxins and excess fluid from the body,13 and play a critical role in removing uric acid from the body.2 Sometimes, the kidneys are damaged and cannot filter blood as well as they could.14 This is called chronic kidney disease or CKD.14
People who are living with gout are at an increased risk of having kidney disease.15 Similarly, people with kidney disease may be more likely to develop gout.16
What does this
mean for me?
While some medicines relieve the symptoms of a gout flare, others work to target uric acid and treat the source of your gout symptoms to prevent gout attacks from happening in the first place. In some instances, even with oral gout medicine gout symptoms continue and become out-of-control.1 That’s why talking to a gout specialist is important.
