![]() This could mean that positive Rh is a risk factor. In addition, 92.2% of the patients had a positive Rh factor. O: Lupus, systemic sclerosis, and Sjogren's SyndromeĪB: Least likely to have rheumatic diseases (possibly because it's a rare blood type and fewer study participants had it.) The study connected specific blood types to the risk of specific conditions: Each of them had a common rheumatoid disease. The most common ones are rheumatoid arthritis, Sjogren's Syndrome, and systemic lupus erythematosus.Ī 2017 study⁵ looked at 823 patients with different blood types. Rheumatic autoimmune diseases cause pain in the joints, tendons, cartilage, and connective tissue. Based on this study, researchers recommend people with blood group B get regular screenings for the condition. ![]() The study found that people with blood group B had a higher risk of developing type 2 diabetes than others. The researchers collected information by sending out an electronic questionnaire. It looked at 300 people with and without diabetes. Type 2 diabetesĪ recent case-control study⁴ tried to determine whether A, B, AB, or O blood groups increased the risk of developing type 2 diabetes. Here are several autoimmune diseases that may be related to blood type. Several studies have connected blood types with specific conditions, but all of them are too small to make definite conclusions. The theory that people with certain blood types are more likely to develop certain autoimmune diseases still warrants more research. The connection between blood types and autoimmune diseases NHS scientists discovered the Er group in September 2022.³ In total, there are 44 blood group systems, which have various antigens, and some are incredibly rare. Only 7% of the population is O-, meaning there’s a shortage of donors. The need for donors with this type is high since 37%² of the population has it? O- blood is often necessary for emergencies when the patient’s blood type isn’t identifiable, as it carries the least risk of causing a reaction. Types without the Rh factor are negative.Īccordingly, there can be eight blood types: Blood types with Rh factor (another protein on the surface of a blood cell) are Rh-positive. Type O doesn't have either A or B antigensĮach blood group receives a further classification depending on the absence or presence of the Rhesus (Rh) factor. ![]() The difference between them dictates the absence or presence of A and B antigens (protein molecules) on red blood cells: ![]() If you don't know your blood type, you can identify it by using a home testing kit, asking the doctor to run a simple blood test, or becoming a blood donor.įour main groups exist. Doctors need to know which blood type someone has when transfusions are necessary. Similar to eye or hair color, blood type is an inherited factor. It's possible to control many autoimmune conditions with medication and lifestyle changes. Nervous system: Multiple sclerosis, Guillain-Barre syndrome Joint and muscle: Rheumatoid arthritis, lupus, Sjogren's syndromeĭigestive tract: Crohn's disease, ulcerative colitis, celiac diseaseĮndocrine system: Hashimoto's disease, Graves' disease, Addison's disease Here are examples of autoimmune diseases: ![]() One million people live with lupus, while 1.4 million have IBD. are lupus and types of inflammatory bowel disease (IBD) called Crohn's disease and ulcerative colitis. The most common autoimmune diseases in the U.S. That's why it's imperative to get the right diagnosis. An autoimmune condition can significantly decrease your quality of life, especially if you don't receive due treatment. Many different types of autoimmune diseases exist and range in severity. ![]()
