Trypanophobia is a fear of the human body parts inside or outside the body. People with trypanophobia are afraid of their own organs, such as: liver, stomach, spleen, kidneys and intestines. They may also be scared by other people’s organs (such as: heart), blood vessels (such as: veins) and even insects’ bodies (such as: bugs). Some people may have a combination of all these fears.

Symptoms of Trypanophobia

People with trypanophobia may experience various symptoms related to their organ fears. These include:

Feeling sick when they see or touch something that looks like a disease-ridden part of the body. For example, if someone sees or touches their own spleen, then they will feel ill. If someone sees or touches a person’s heart, then they will feel ill.

Fear of going into a hospital because they think it is where diseases come from.

Being unable to go out alone at night, because they worry that they might get bitten by a mosquito while walking around.

Feeling very nervous when driving, because they fear getting in an accident due to being afraid of their own organs. This may cause them to drive slowly and cautiously. Sometimes people with trypanophobia will not allow anyone else near them during this time either.

Fear of getting injections and blood tests. They also fear IV’s and other medical equipment.

People with trypanophobia may experience various emotions related to their organ fears. These include:







Tingling sensations

Shortness of breath

Rapid heart rate

People with trypanophobia may display various behaviors related to their fears. These include:

Refusing to get a blood test or getting other medical checks for internal organs

Arranging their life to avoid hospitals and medical treatment

Only going to doctors they know and trust, or refusing to go to any

Spending a lot of money on vitamins and over-the-counter medicine for minor issues such as coughs and colds, even if they do not cause discomfort or pain

Refusing to have surgery unless it is absolutely necessary

Trying to spend as much time as possible in clean, well-lighted areas

Increasing their use of alcohol and cigarettes due to stress and anxiety

Making sure that their surroundings are kept clean and free of dirt and insects at all times

Avoiding activities that involve bugs or dirt, such as camping and hiking

Refusing to allow anyone to touch them or get too close to them

Seeking out the company of other people when afraid as a protective measure against diseases

Going out only in bright daylight and avoiding the night as much as possible

Washing their hands frequently to get rid of any contaminants on their skin

Refusing to eat raw food such as fruit or vegetables, insisting on cooked food instead

Seeking medical treatment for minor illnesses such as coughs and colds, even if they do not cause discomfort or pain

When faced with a blood test or injection, experiencing shortness of breath, rapid heart rate, sweating, shaking and other signs of extreme fear

Avoiding medical treatment as much as possible

How people behave when faced with a needle for a blood test or an injection will depend on their personality. Some people will go into a frozen state and be unable to do anything but panic. Other people will become aggressive, either verbally or physically. Still others will start crying or screaming in fear.


There is no known cure for trypanophobia. However, it is possible to make a person’s fears less severe or even manageable with treatment.

Cognitive-behavioral therapy is one of the most common ways to treat phobias. The patient is made to face their phobia on a gradual basis until they reach the point where their fear is manageable.

Systematic desensitization is another treatment option. The patient is induced to feel relaxed, then a small amount of fear is introduced. The patient then feels slightly afraid but is able to control their fear response. This process is repeated until the patient can be faced with their fear and stay calm.

Medication such as Xanax can also help reduce the intensity of a panic attack.

Needles should never be forced into someone with trypanophobia as this can cause further injury, possibly severe. If a blood test or injection is absolutely necessary then the person should be sedated first and only a doctor should carry out the procedure.

A phobia of needles and hospitals can severely impact the quality of life for people who have it to the point where they may become housebound, unable to work or even leave their own home.

Those who have a phobia of blood, needlestick injury, or needlestick injury combined with a fear of watching a needle puncture their skin (blood donation), risk the possibility of developing blood-borne pathogens in their blood if they are injured by a contaminated needle.

If you or someone you know is experiencing any of these symptoms and feels uncomfortable with medical treatment, please seek out a doctor immediately.

It’s not all bad though… at least you don’t have any fear of flowers.

There are also two specific phobias that don’t seem to fit into any of the above categories.

Bibliophobia: fear of books

Hierophobia: fear of priests (Very reasonable considering what we’ve had to deal with in the Church)

Then there’s one last phobia that doesn’t make sense based on what it’s definition is.

Geliophobia: fear of laughter (???


I can’t find a rational explanation for this one, any ideas?

So that’s about it for now. Let me know if you have any questions, I’m happy to answer them.

(*)If you’re wondering why you’ve never seen a person with arachnophobia (fear of spiders), it’s because people with this fear almost always get themselves eaten by them. They either live their lives in terror of spiders or they just kill themselves.
