Introduction

Did you know that your blood type may put you at risk for certain diseases? It’s true! Your blood type can influence your risk for certain conditions, including some that can be deadly. In this article, we’ll discuss the diseases that are associated with each blood type and what you can do to reduce your risk. We’ll also provide some tips on what to eat and what to avoid to keep your blood type healthy. So, if you’re curious about how your blood type may affect your health, read on!

You’re born with your blood type, which is determined by which antibodies are present on the surface of blood cells. Most of us don’t think too much about it. But science is discovering that your blood type may have real implications for your health, potentially raising your risk of serious disease from COVID to cancer. Read on to find out more—and to ensure your health and the health of others, don’t miss these Sure Signs You May Have Already Had COVID.

A study published last March in The Annals of Internal Medicine found that people with type O blood may have a 12% lower risk of testing positive for COVID and a 13% lower risk of developing severe COVID-19 or dying from the disease. In a different study published that month, researchers from Harvard University and Oklahoma Blood Institute (OBI) found that those with Type A blood are more likely to become infected with COVID. That blood type seems to provide a “stickier” surface for the virus’s spike proteins to cling to.

In a study published earlier this year in BMC Cancer, researchers looked at genotyping data from thousands of residents of China. They found that people with blood type AB were 34% more likely to develop esophageal cancer, compared to people with type O blood. Additionally, researchers found that people with AB blood had a 44% higher risk of stomach cancer, and people with type A blood had a 37% higher risk. The researchers aren’t sure why this may be and have called for more studies.

Having a non-O blood type (meaning A, B and AB) puts you at higher risk for heart disease. That’s because of the ABO gene, which is present in people with A, B, or AB blood types. It makes red blood cells of those types stickier and more resistant to blood flow. One study found that people with type A or B blood were 51% more likely to develop blood clots in the veins and 47% more likely to develop blood clots in the lungs.

According to a study published in Neurology, people with AB blood are 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types. What may be responsible: factor VII, a protein that helps blood to clot. High levels of factor VII are related to a higher risk of dementia, and people with AB blood have a higher average level of factor VIII than people with other blood types.

Analyzing health data from more than 5 million people in Sweden, researchers at the Karolinska Institute in Stockholm found that people with type A blood are more likely to have blood clots, while those with type O blood are more likely to have a bleeding disorder, particularly gastric ulcers and duodenal ulcers. Women with type O blood are more likely to develop pregnancy-induced high hypertension (high blood pressure), the scientists found.
