It occurs when calcium pyrophosphate crystals build up in the joints, causing sudden and severe pain, inflammation, and swelling. This article will explore the causes, symptoms, and treatment options for pseudogout, providing valuable insights into this often misunderstood condition. So, if you're curious about pseudogout and want to learn more, keep reading to unravel the mystery behind this puzzling condition.

What Is Pseudogout?



Pseudogout, also known as calcium pyrophosphate deposition disease (CPPD), is a type of arthritis that causes sudden and severe joint pain and inflammation. Unlike gout, which is caused by uric acid crystals, pseudogout is characterized by the formation of calcium pyrophosphate crystals in the joints. These crystals irritate the joint tissues, leading to pain and inflammation.


The exact cause of pseudogout is not fully understood. However, it is believed to be related to an imbalance in the levels of calcium and pyrophosphate in the body. As people age, the body's ability to regulate these minerals decreases, leading to the formation of calcium pyrophosphate crystals. Certain risk factors, such as genetics, joint trauma, and other medical conditions like hyperparathyroidism and hemochromatosis, can increase the likelihood of developing pseudogout.

Risk Factors

There are several risk factors that may increase your chances of developing pseudogout. Age plays a significant role, as the condition is more common in individuals over the age of 60. Additionally, genetics can play a role, as pseudogout tends to run in families. Other risk factors include joint trauma, surgery, underlying medical conditions like hyperparathyroidism or hemochromatosis, and metabolic disorders such as hypothyroidism.


Pseudogout is a relatively common condition, affecting approximately 3-4% of the general population over the age of 60. As the population continues to age, the prevalence of pseudogout is expected to rise. It is more common in older adults and women, although it can affect individuals of any age and gender. The frequency of acute attacks tends to increase with age, with some individuals experiencing multiple episodes per year.


Acute Attacks

The most common symptom of pseudogout is the sudden onset of severe joint pain, often in the knee, wrist, ankle, or shoulder. The affected joint may appear swollen, red, and warm to the touch. The pain associated with an acute attack can be intense and debilitating, making it difficult to perform everyday activities. These episodes typically last for a few days to weeks and then subside on their own.

Chronic Pseudogout

Chronic pseudogout refers to the persistence of symptoms or recurrent acute attacks over a longer period of time. In some cases, the crystals may accumulate in the joint and cause chronic inflammation and damage. This can lead to joint stiffness, limited range of motion, and the development of joint deformities over time.


If left untreated, pseudogout can lead to several complications. Chronic joint inflammation can result in joint damage, leading to osteoarthritis or joint erosion. In some cases, it may cause the formation of large calcium pyrophosphate crystals, known as tumoral calcinosis, which can be painful and require surgical removal. Furthermore, pseudogout can increase the risk of developing other health conditions such as cardiovascular disease and kidney stones.


Medical History

To diagnose pseudogout, your healthcare provider will start by taking a detailed medical history. They will inquire about your symptoms, the duration and frequency of your pain, and any recent joint injuries or surgeries. They will also ask about your family history of pseudogout or other crystal-related arthropathies.

Physical Examination

A physical examination will be conducted to assess the affected joint and other joints for signs of inflammation and tenderness. Your healthcare provider may also check for the presence of joint effusion (excess fluid in the joint), as this often occurs in pseudogout.

Laboratory Tests

To confirm the diagnosis, laboratory tests can analyze the synovial fluid from the affected joint. The fluid will be examined for the presence of calcium pyrophosphate crystals. A high white blood cell count and elevated C-reactive protein (CRP) levels may also be indicative of pseudogout.

Imaging Tests

Imaging tests, such as X-rays or ultrasound, may be performed to visualize the affected joint and rule out other possible causes of joint pain. X-rays can reveal the presence of calcium pyrophosphate crystals or joint damage, while ultrasound may show signs of inflammation and fluid accumulation.



The primary goal of medication treatment for pseudogout is to manage pain and reduce inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) are often prescribed to alleviate symptoms during acute attacks. In more severe cases, corticosteroids may be administered orally or injected directly into the affected joint to provide rapid pain relief and reduce inflammation. Disease-modifying antirheumatic drugs (DMARDs) may also be used to help prevent future flare-ups.

Joint Aspiration

In cases of severe joint inflammation or persistent symptoms, joint aspiration may be performed. This involves removing the excess fluid and calcium pyrophosphate crystals from the affected joint, providing immediate pain relief and reducing swelling. Joint aspiration can be done using a needle and syringe under local anesthesia.

Lifestyle Changes

Making certain lifestyle changes can help manage and prevent pseudogout attacks. Avoiding trigger foods, such as red meat and alcohol, that may increase the risk of flare-ups is recommended. Regular exercise, including low-impact activities like swimming and cycling, can help maintain joint flexibility and strengthen muscles. It is also important to stay well-hydrated and maintain a healthy weight to reduce stress on the joints.

Alternative Therapies

Some individuals find relief from pseudogout symptoms through alternative therapies, such as acupuncture, massage therapy, or the use of herbal supplements. While these therapies may provide additional pain relief and improve overall well-being, it is important to discuss their use with a healthcare provider, as they may interact with prescribed medications.

Dietary Measures

A balanced diet can play a role in preventing pseudogout attacks. Limiting the intake of foods high in purines, such as organ meats, shellfish, and alcohol, can help reduce the risk of crystal formation. Instead, focus on consuming plenty of fruits, vegetables, whole grains, and lean proteins to maintain overall joint health. Staying well-hydrated by drinking an adequate amount of water each day is also crucial.


Regular exercise is not only beneficial for overall health but can also help prevent pseudogout attacks. Engaging in low-impact exercises, such as swimming, walking, or cycling, can improve joint flexibility, strengthen muscles, and support weight management. It is important to start slowly and gradually increase the intensity and duration of exercise to avoid joint strain or injury.

Maintaining a Healthy Weight

Maintaining a healthy weight is essential in managing and preventing pseudogout. Excess weight puts additional stress on the joints, increasing the risk of joint damage and inflammation. By adopting a nutritious diet and engaging in regular physical activity, you can achieve and maintain a healthy weight, reducing the burden on your joints and minimizing the likelihood of pseudogout flare-ups.


Long-Term Outlook

The long-term outlook for individuals with pseudogout varies depending on the severity of the condition and the presence of any complications. With proper treatment and lifestyle modifications, most individuals can effectively manage their symptoms and prevent frequent acute attacks. However, pseudogout is a chronic condition and may require ongoing treatment and monitoring to ensure optimal joint health.


Without timely treatment and management, pseudogout can lead to complications such as joint damage, stiffness, and deformities. Chronic inflammation can also increase the risk of developing osteoarthritis. Additionally, the accumulation of large calcium pyrophosphate crystals can cause tumoral calcinosis, which may require surgical intervention to alleviate pain.

Follow-Up Care

Regular follow-up appointments with a healthcare provider are crucial for individuals with pseudogout. These visits allow for ongoing monitoring of symptoms, medication adjustments if necessary, and the identification of any potential complications. Your healthcare provider may also recommend regular imaging tests, such as X-rays, to assess joint health and identify any changes over time.
