There are certain arthritic conditions that we know a specific cause for. Gout, for example, we know is caused by a lack of an enzyme, xanthine oxidase, and as a result the level of uric acid in the blood is higher than normal. This high level results in crystals separating out and being deposited in joints and other areas of the body.

In most cases of arthritis there are more than one factors involved. Some people have a genetic risk that leaves them susceptible to arthritis. Some arthritis runs in families but the precise genetic link is not yet clear.

Environmental factors contribute to arthritis. Individuals involved in repetitive high physical demand in a particular joint will be prone to arthritis. Injury can cause damage or mis-alignment of the joint leading to undue wear.

Infections in the joint (septic arthritis) can lead to arthritis. Some general infections can cause joint pains but this goes away when the infection subsides.

There is no clear evidence that climate contributes to arthritis. These joint problems are worldwide. I know a lady with osteoarthritis. She could tell with reasonable accuracy the weather outside when she wakes up in the morning by the level of stiffness and pain.

Another patient who endures regular winter aches and pain in UK, was remarkably pain free during a winter spent in the Spain where the weather in mild and the sky is blue. Pain is subjective and the intensity does not necessarily depend on the severity of arthritis. Of course, winters in UK are cold, damp and gloomy and the sky usually grey.
