Blood Type A Linked to Liver Disease Risk
22 Nov, 2025
Summary
- Blood type A may increase the risk of autoimmune liver disease.
- Blood type B appears to lower the risk of primary biliary cholangitis.
- Study suggests blood type analysis could aid in risk identification.
New research indicates that a person's blood type may influence their susceptibility to autoimmune liver diseases. The study found that individuals with blood type A could be at an increased risk of developing such conditions, which can lead to severe liver damage.
In contrast, the research suggests that people with blood type B are less likely to develop primary biliary cholangitis (PBC), a specific type of liver disease. The findings propose that blood type A is most common among patients with chronic liver disease, followed by O, B, and AB types.
These findings support the idea that blood type analysis might become a valuable tool in clinical practice for identifying individuals predisposed to autoimmune liver diseases, especially PBC. The study also noted that females and older individuals were more susceptible.
