What causes pseudogout?

Pseudogout is caused by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the joints. CPPD crystals can form when there is too much calcium or pyrophosphate in the body, or when the pH of the joint fluid is too low.

Some conditions that can increase the risk of pseudogout include:

* Older age: Pseudogout is most common in people over the age of 65.

* Certain medical conditions: Pseudogout is more likely to occur in people with certain medical conditions, such as hypothyroidism, hyperparathyroidism, and hemochromatosis.

* Joint injury: A joint injury can trigger an attack of pseudogout.

* Surgery: Surgery can also trigger an attack of pseudogout.

* Medications: Certain medications, such as diuretics and corticosteroids, can increase the risk of pseudogout.

In some cases, pseudogout can be caused by a genetic disorder.
