Blood Type A Personality Weaknesses

  1. Type As know exactly what they want and how they want it, so it can be difficult for them whenever someone else wants something different. They may be quick to shut down others’ ideas if they don’t align with what the type A thinks is best, and they can have a hard time admitting when they’re wrong.[5]
    • It’s important for type As to remember to look at things objectively. Just because an idea came from someone else doesn’t automatically mean it’s bad. They should consider what’s best for the whole group or project rather than what’s best for themselves.
  2. Type As are rule followers. They place a lot of value on etiquette and social standards, and they often have an individual moral code that they strictly follow. On the rare occasion they do break the rules, things usually end poorly, often as a self-fulfilling prophecy.[6]
  3. People with type A blood often take things too personally, which leads to them feeling hurt quite frequently. Because they try so hard to make sure everything goes smoothly, any critique on the situation can feel like a personal attack because they put so much of themselves into everything they do.[7]
    • Type As need to understand that constructive criticism isn’t an insult; it’s valuable feedback that allows them to better themselves or their project. There’s always room for improvement, and that isn’t a bad thing!
  4. Because people with type A blood tend to be perfectionists, they often panic when even one little thing goes wrong. They may take on additional tasks to try to correct the situation, which often leads to them becoming even more stressed and overwhelmed.[8]
    • Many type As benefit from allowing someone else to take charge and stepping away for a bit. They need to understand that some things are out of their hands and it’s okay to take a breather now and then.
  5. Reserved and shy, Type As often seem secretive and closed-off to others. They tend to keep to themselves because they struggle with self-consciousness and have difficulty trusting others.[9]

Blood Type A Compatibility

  1. Since type As are often perfectionists and strict rule-followers, it makes sense that they’d look for someone who also has those traits—which often means they end up with another type A. Type ABs are adaptable and possess traits of both types A and B, so they may also have some of the characteristics a type A looks for in a partner.[10]
    • Some also say type As are compatible with type Os because Os are confident leaders who can help break the type A out of their shell.
    • Type As are least compatible with type Bs because Bs are outgoing, impulsive, and can be impatient and reckless.
    • Type As get to know people slowly, so they’re not looking for someone who wants to rush into a relationship.

Blood Type A Health Advice

  1. Type A has a 5% higher chance of heart disease than other types, but don’t panic—having this blood type doesn’t automatically mean you’ll have heart disease. Still, it’s always a good idea to eat healthy, balanced meals, so try to eat 5 portions of fruit and veggies a day and avoid saturated fats.[12]
    • Saturated fats include foods like butter, cream, sausages and fatty meats, and cakes.
    • Go for unsaturated fats instead, like fish, avocado, nuts, and seeds.[13]
    • Eating whole grains, fruits, and vegetables, and drinking green tea have also been associated with reducing the chances of stomach cancer. Those with type A blood have a 20% higher chance of stomach cancer compared to types O and B.[14]
  2. Another important way to reduce the chances of heart disease is to stay active. Regular exercise lowers your cholesterol and helps keep your blood pressure at a healthy level. Try aerobic exercises like walking, swimming, or dancing.[15]
  3. People with type A blood have higher levels of cortisol, the stress hormone. If you’re type A, you may have more difficulty dealing with stressful situations than other people. Remember to take care of yourself and do the things that calm you down, whether that’s reading a book, taking a bubble bath, or practicing meditation.[16]

Blood Type Theory Overview

PDF download Download Article
  1. Also known as ketsueki-gata, this theory is prominent in countries like Japan and South Korea, and it has begun gaining interest in Western countries like the United States. Someone might ask “What’s your blood type?” the same way we ask “What’s your zodiac sign?”[17]
    • Like zodiac signs, your blood type is believed to affect your personality strengths and weaknesses, how you behave, who you’re compatible with, and what careers you’re most suited for.
    • While this theory is a pseudoscience and there is no scientific evidence to support it, it’s mostly considered a fun way to get to know someone and break the ice.
    • The 4 blood types are A, B, AB, and O. Different antigens, or molecules on the surface of red blood cells, determine your blood type.[18]
    • Whether your blood type is positive or negative does not seem to affect your personality. So someone with A+ blood and someone with A- blood would have similar traits, for example.
    • The blood type personality theory originated in 1930 when Japanese professor Tokeji Furukawa published a report called “A Study of Temperament and Blood-Groups” in the Journal of Social Psychology, in which he argued that establishing a link between blood type and personality might aid in the study of temperament.[19]

  1. These individuals are empathetic, strong, and decisive, but have been associated with erratic behavior. Those who have this blood type are also creative but have a tendency to be irresponsible and unforgiving. Their personalities tend to clash with those of type A people.[20]
  2. They’re rational and controlled, but they’re highly critical and forgetful. They have characteristics of both type A and type B, and because this blood type is rare, they’re considered unique and highly appreciated in Japan.[21]
  3. They’re determined, competitive, and in touch with their intuition, but they can be aggressive and cold. Those who have type O blood also tend to be workaholics. They often seem especially selfish to those with type A blood.[22]
