Causes

It is estimated that about 3.5-10% of people suffer from trypanophobia; 80 percent of people with trypanophobia also have a close relative who has injection phobia. There may be a genetic component to the phobia.

Another cause is a previous traumatic experience with injections, possibly a response that causes them to pass out or almost pass out. There may be an evolutionary response to the dangers of sharp objects puncturing the skin. The cause of trypanophobia depends in part on the type.

Types

There are several types of trypanophobia, the characteristics and causes of which vary:

  • Vasovagal trypanophobia
  • Associative trypanophobia
  • Resistive trypanophobia
  • Hyperalgesic trypanophobia
  • Vicarious trypanophobia

Vasovagal trypanophobia

Vasovagal trypanophobia is a type of trypanophobia that involves a vasovagal reaction. A vasovagal reaction occurs when a person experiences a sudden increase and then a decrease in heart rate and blood pressure. Changes in heart rate and blood pressure can cause fainting.

It is not entirely clear whether the vasovagal response causes vasovagal trypanophobia or whether trypanophobia causes the vasovagal response. However, it is believed that this fainting response is hereditary and then leads to a phobia of injections due to their association with the negative experience of fainting, which creates a cycle. In extremely rare cases, this type of trypanophobia can lead to a heart attack or stroke.

Associative trypanophobia

Associative trypanophobia is a type of trypanophobia associated with a traumatic event. A person with this fear of injections may have had an extremely painful medical procedure or had a severe reaction to a previous injection, for example. Less commonly, the person with Associative Trypanophobia may have been with someone else who has had a medical procedure or an extremely painful injection reaction.

Regardless of the specific details, this type of injection phobia is caused by an association between the injections and a negative experience.

Resistive trypanophobia

Resistive trypanophobia is a type of trypanophobia that involves the fear of being controlled. The cause could be previous experiences with needles that required them to be restrained, most often during childhood.

Some people with this type of trypanophobia may become aggressive or violent when in situations involving injections, which may require them to be restrained to avoid injuring themselves or others. In this type of trypanophobia, there is a fear of both the needle and control or restraint.

Hyperalgesic trypanophobia

Hyperalgesic trypanophobia is a type of trypanophobia related to increased sensation of physical pain or increased sensitivity to physical pain. Children tend to experience physical pain from injections more intensely than adults.

The increased sensitivity or pain caused by the needles and the associated fear can also be caused or intensified by injury, inflammation, stress, arthritis, autoimmune diseases, chronic illnesses, or adverse experiences of the patient. childhood. With this type of trypanophobia, the fear of injections has more to do with physical pain than the actual needle or injection.

Vicarious trypanophobia

Vicarious trypanophobia is a type of trypanophobia that involves extreme fear of injections when someone else meets the needle.

A person with indirect trypanophobia may experience the same symptoms as other types of trypanophobia, including a vasovagal response, when they witness another person receiving an injection. Likewise, trypanophobia can be caused by seeing someone else have a traumatic experience with a needle or a medical procedure.

Processing

Treatment options for trypanophobia include therapy and medication. There are also coping strategies that can help prevent fears and anxieties and reduce their severity when they arise.

Therapy

Cognitive behavioral therapy, or CBT, is an effective psychotherapeutic treatment often used for trypanophobia. It involves strategies that take into account the connections between thoughts, behaviors and emotions.

This treatment may also include systematic desensitization therapy (i.e., exposure therapy), which uses increasing levels of fear exposure in a safe and controlled environment to reduce the fear response. Hypnosis has also been shown to be effective.

Medication

When needles are needed, sometimes medication is applied to the skin first so that the pain sensation is lessened or not felt at all. When sedation is required for an operation or procedure, the patient may be sedated before any needle is used. However, this can increase the problem because the patient does not have the control or the ability to overcome the phobia.

Medications are generally avoided to treat phobias because psychotherapy options tend to be more effective and do not come with side effects. When drugs are used, it is usually for short term use. Antidepressants such as selective serotonin reuptake inhibitors, or SSRIs, or beta blockers are sometimes prescribed for anxiety.

To face

Relaxation techniques are recommended for dealing with trypanophobia, except in people with vasovagal trypanophobia. Indeed, relaxation techniques can decrease heart rate and blood pressure.

A word from Verywell

Talk to your doctor about how to receive care without needles or with minimal use of needles. Depending on your medical needs, needle injections may not be necessary. If needles are needed for your care, there are adjustment and treatment options to help you overcome trypanophobia and get the care you need.
