Gout

Uric acid is a chemical which is a natural part of the normal breaking down and building up of food and body tissues. The level in the blood can be measured and shows how much there is in the body overall. The condition of raised blood uric acid is called hyperuricaemia. When this is present the uric acid which is normally dissolved in the blood may, from time to time, form microscopic crystals in the joint. These crystals set up the inflammation which is called acute gouty arthritis or acute gout.

It follows that gout may develop in persons whose uric acid is higher than normal. There are many causes of this.

The following are some of the more common causes:
Higher than normal levels of uric acid can be part of the inherited make-up of some families
Obesity
High alcohol intake
High intake of food containing purines (see below)
Some of the drugs used to treat high blood pressure.
Less commonly, longstanding kidney disease may result in high blood levels of uric acid.
