The buildup of calcium pyrophosphate dihydrate crystals within and around the joint areas causes pseudogout, a type of joint inflammation, or arthritis, according to MedicineNet. Many medical professionals often refer to pseudogout by the name CPPD, or calcium pyrophosphate deposition disease.
Associated with degenerative arthritis, pseudogout occurs more frequently with age and appears mainly in the elderly, explains MedicineNet. Dehydration stands as another potential cause of pseudogout, and can lead to acute attacks in people, such as hospitalized patients or those recuperating after operations. Hyperparathyroidism and the hormonal effects it has on calcium metabolism can also lead to the development of pseudogout.
