Blood Type and Liver Disease Risk: A new study has found that people with blood group A have a higher risk of autoimmune liver disease than people with other blood groups. The risk of these diseases has been seen to be less in people with blood group B. With timely testing, healthy lifestyle and regular monitoring, the liver can be protected for a long life.

People with blood group A are at higher risk of autoimmune liver disease.

Blood Type Can Predict Liver Disease Risk: Your blood group gives many information related to health. Most people see their blood group only as a medical information. Whenever there is an emergency, only then treatment is done on the basis of blood group. However, blood group can also give information about many diseases. A recent research has revealed that your blood group can also tell a lot about your risk of liver related diseases. Especially the risk of autoimmune liver disease has been found to be higher in people with blood group A. This is a condition in which the body’s immune system mistakenly attacks the liver. Many surprising things have come to light in this research.

According to TOI report New research has found that people with blood group A have a higher risk of autoimmune liver disease, while people with blood group B have a lower risk. This study has been published in the journal Frontiers and in this study the data of more than 1200 people was analyzed. Out of these, 114 patients were suffering from autoimmune liver disease. Researchers found that after blood group A, people with blood group O, B and AB were at risk of this liver disease. Whereas in blood group B people, apart from autoimmune disease, the risk of primary biliary cholangitis (PBC) was also found to be less.

What is autoimmune liver disease?

According to doctors, liver diseases caused by alcohol, viral infection or bad lifestyle are different. Autoimmune liver disease occurs when the body’s immune system mistakenly starts attacking the liver or its cells. In autoimmune hepatitis, the immune system directly damages the liver cells. In primary biliary cholangitis, the body’s immune system damages the bile ducts. This causes bile to accumulate in the liver and over time can lead to scarring and cirrhosis. These diseases grow slowly and may develop without symptoms for many years.

What is the connection between blood group and liver disease?

Actually, our blood group A, B, AB or O depends on what type of antigens A, B or H are present on our red blood cells. Scientists believe that these antigens affect not only the blood group but also the body’s immune and inflammation response. The study observed that the presence of A antigen was higher in patients with autoimmune liver disease, indicating that this group may be more likely to have immune dysfunction. Having blood type A does not guarantee that you will get liver disease, but it may increase your risk. Therefore, if you notice initial problems like frequent fatigue, joint pain, heaviness in the right side of the stomach, itching in the skin, loss of appetite or jaundice, then you should get yourself checked immediately.
