Having O positive blood type is one of the most common blood types in humans. Specifically, approximately 37% of people have o positive blood type, while another 6% are o negative blood type. Knowing your blood type can be valuable in a number of circumstances, so it is important to understand what it means to have o positive or o negative blood type and the implications these different types have on a person’s health and lifestyle.

O-positive and O-negative are two different variations of the most common human blood group, O. It is also important to understand how this designation affects our compatibility with other people when donating or receiving a transfusion, as well as how it could be relevant during pregnancy or childbirth. This article will explain the basics of what it means to have either an O-positive or O-negative blood type, including the traits and characteristics associated with each one. As well as outlining some examples of what situations may arise for those individuals with either or both of these types:

  • Compatibility with other blood types when donating or receiving a transfusion.
  • Relevance during pregnancy or childbirth.
  • Traits and characteristics associated with each type.

What is O Positive Blood Type?

O positive is the most common blood type in the world and it is found in around 40% of the population. Being O positive means that your blood contains a special type of protein called an antigen. This antigen is present on the surface of your red blood cells and it helps in the clotting of your blood. It also provides immunity to diseases like the measles, mumps, and rubella.

Let’s take a closer look at what being O positive blood type means.

Who can have O Positive Blood Type?

O Positive blood type is the most common blood type and is found in 38% of the population. O Positive blood is sometimes referred to as “universal donor” since those people with this type can give their red blood cells to anyone, regardless of their recipient’s blood type. Their donated red blood cells are compatible with all other ABO types.

People with O Positive blood have antigens which consist of A and B proteins on their red blood cell membranes; however, these antigens do not match either A or B. This means that people with O Positive blood are only able to receive transfusions from other people who also have O Positive or O Negative (Universal Recipient) blood types. Other characteristics include:

  • People with O positive have a higher prevalence for certain diseases such as iron deficiency anemia, thalassemia, TTP (thrombotic thrombocytopenic purpura),/and diabetes compared to those with other types.
  • Statistically speaking, people with o positive tend to be more resistant to malaria.
  • They may require fewer transfusions due to their unique antigen profile.
  • They are more likely than any other group of people to donate a unit of red cells.
  • Their plasma is considered “universal”, and therefore they can simultaneously help recipients who are AB positive.

What are the Benefits of Having O Positive Blood Type?

If you have O positive blood type, you are among the blessed few, as this is the most common of all types. In general, people with O positive blood type are especially healthy and resistant to many illnesses. Let’s look at some of the benefits of having O positive blood compatibility:

  1. Universal Donors and Receivers: People with O positive blood type can donate their red blood cells to any other group, and can receive red cells from anyone in any group too. This means that O+ is a universally accepted donation group also known as a “universal donor”. In dire medical situations where an immediate blood donation is required, these individuals can help save lives with their universal acceptance.
  2. Resilience: Individuals with an O+ blood type enjoy greater natural resilience to many infectious diseases like malaria, HIV and leprosy compared to those who don’t possess this particular antigen in their blood plasma. They also have a natural flexibility that allows them to adapt to changes in climatic conditions very easily.
  3. Immunity ​from​ Genetic Diseases: The protein antigens present on the surface of red cells provide added protection against genetic diseases like Hemophilia A and B which are common among other types except for 0+. This provides people with 0+ added immunity from many autoimmune diseases caused by genetic anomalies within the red cell that affect its ability to clot or provide oxygenation like Sickle Cell Anemia or Thalassemia.
  4. Increasing Positivity Levels: Genetically speaking, having an extra dose of just one antigen enables individuals who possess it leverage psychological positivity which brings positive thoughts leading towards enhanced optimism resulting in better coping abilities in challenging situations giving them an edge over others​!

What are the Risks of Having O Positive Blood Type?

O-positive blood type is the most common type among the 8 main blood types in the US. While having O-positive blood type has its advantages, there may be some risks associated with it too.

In this article, we will explore the potential risks that accompany carrying this blood type and how to adequately manage them:

How to Manage O Positive Blood Type?

Having type O positive blood can be beneficial in some scenarios, but it does come with risks. First, individuals with this blood type are more likely to suffer from iron overload, which can lead to organ damage and potentially life-threatening conditions if not properly managed. Additionally, those with type O positive blood are at increased risk for developing heart disease and diabetes.

To reduce the risk of health problems associated with having O positive blood type, it is important to maintain a balanced lifestyle which includes building healthy habits into everyday life. Management starts with understanding the specific needs of your body and talking to your doctor or healthcare provider about which lifestyle changes would best suit you.

Some tips that may help manage your condition include:

  • Eating a balanced diet high in whole grains, fruits, vegetables and lean proteins as well as low in saturated fats.
  • Regularly exercising to promote overall good health as well as physical wellness.*
  • Staying hydrated throughout the day by drinking plenty of water.*
  • Limiting alcohol consumption.*
  • Quitting smoking if applicable.*
  • Maintaining regularly scheduled doctor appointments.*
  • Taking medication prescribed by a healthcare professional, such as iron chelators if needed.*

*Consult your doctor or healthcare provider before beginning any lifestyle change or medical treatment.


Overall, O-positive blood type is the most common blood type in the world and provides many advantages for those with this blood group. Having O+ blood type increases red and white blood cell production, reduces risk of anemia, leads to an increased ability to withstand low oxygen environments, makes it easier to donate and receive donations from other O+ individuals, and also reduces the risk of developing certain conditions such as thalassemia.

Additionally, O-positive individuals can benefit from a healthier lifestyle by including regular exercise routine paired with balanced meals rich in iron.

Ultimately, understanding your own blood type is essential for making more informed decisions regarding your health and care. Knowing the specific qualities of your respective blood type can help you take better precautions to protect yourself against possible illnesses or identify how to better manage existing ones depending on your unique genetic makeup:

  • Reduced risk of anemia
  • Increased ability to withstand low oxygen environments
  • Easier to donate and receive donations from other O+ individuals
  • Reduced risk of developing certain conditions such as thalassemia
