Which Blood Type Has The Weakest Immune System?

The major role of the immune system is to prevent or limit infection. Our immune system is essential for our strength. Without an immune system, our bodies will expose to getting sick from bacteria, viruses, fungi, and more. 

Our immune system keeps us healthy. The immune system is spread everywhere in the body, including cells, organs, proteins, and tissues. The immune system also clears dead and faulty cells from our bodies.

In this post, we will introduce some main characters of the immune system.

I have already shared a post about how Can I Boost My Immune System? I hope you read this post.

Types of immunity

Each person’s immune system is different, but it becomes stronger during adulthood as a general rule. This is because we have been exposed to more pathogens and developed more immunity at this stage. That is why teens and adults are less likely to get sick than children.

There are four types of human immunity:

1. Active immunity: This type of immunity is created by our immune system when we contact a harmful pathogen.

2. Passive immunity: Something other than one’s immune system produces this type of immunity.

3. Adaptive or acquired immunity: Adaptive immunity is the type of immunity that occurs after exposure to a pathogen or infection or when we get a vaccination.

4. Innate Immunity: This type of immunity comprises various barriers that defend against viruses, bacteria, parasites, and any foreign substances throughout the body.

Immune system disorders

Immune system disorders

The immune system is so complicated. Therefore there, it can work wrong in many potential ways. Types of immune disorder into three categories:


When our immune system does not work well, it can lead to immunodeficiencies such as age, obesity, and alcoholism. Also, AIDS is an example of acquired immunodeficiency.

In some cases, immune deficiencies can be acquired, for instance, in chronic granulomatous disease where phagocytes do not function properly.


The immune system wrongly targets healthy cells in autoimmune conditions rather than faulty cells. In this scenario, they cannot recognize themselves. As a result, a person may lead to autoimmune diseases such as diabetes, celiac disease, and rheumatoid arthritis.


 The immune system overreacts to damage healthy tissue and lead to hypersensitivity. Sometimes, our bodies respond to an allergen so strongly that it can be life-threatening.

Which blood type has the weakest immune system?

Blood group type A has the weakest immune system because people with this blood type usually have a weak immune system. Therefore, they are more likely to get autoimmune dieses such as spondyloarthropathy, vasculitis, undifferentiated connective tissue disease, Behçet’s disease, and Rheumatoid arthritis.

Blood group type O has the strongest immune system because people with this blood type have a lower risk of getting immunodeficiencies as their immunity is much stronger than others.

Physical activity isn’t just to build muscles and help yourself de-stress; it’s also an important part of supporting a healthy immune system.


Water plays a main role in helping the immune system of your body. Dehydration sometimes leads to an impaired immune system.

Get plenty of sleep

A person who doesn’t get enough sleep tends to get sick after exposure to viruses. So to give your immune system the best chance to fight infection and illness, it’s important to get enough sleep.

Having stress suppresses your immune system, increasing your chance of infection or illness. Deep breathing, mediation, prayer, exercise, and everyday activities can help you minimize your stress.
