Published: Dec 22, 2023
MGUS might not have symptoms, but certain factors can increase the risk of developing it. Knowing these can help you stay informed about your health.

Age and Ethnicity
MGUS is more common as people age, particularly after 50, with a higher prevalence in African Americans. Studies suggest that genetic predisposition might play a role, as demonstrated by higher rates in people with a family history of MGUS or related conditions.
Gender Differences
Men are more likely to develop MGUS than women, with studies indicating this trend across various populations. The reasons for these gender differences aren't fully understood, but they emphasize the importance of regular health screenings, especially for men over 50.

Environmental and Lifestyle Factors
Although no direct environmental causes have been established, some studies suggest occupational exposure and lifestyle choices could influence MGUS risk. Maintaining a healthy lifestyle might help manage the risk, although it hasn't been proven to prevent MGUS.
