Dizziness after blood draw

If you feel dizzy after having your blood drawn, it is most likely because the person having your blood drawn has hemophobia. Hemophobia is also a common and widespread symptom, which is mainly caused by psychological problems. However, hemophobia is not untreatable. As long as the method is appropriate, hemophobia can be improved to a certain extent. Here we will introduce to you the treatment method of hemophobia!

1. Treatment principles

People with hemophobia may feel terrified and nauseated at the sight of blood in mild cases, or lose consciousness in severe cases. These problems may affect the patient's work and life. However, hemophobia is not an incurable disease. The treatment of this disease mainly starts with eliminating fear, and the way to overcome fear is mainly cognitive-behavioral therapy. Psychotherapists usually let patients directly face the feared objects or places, use exposure to eliminate the fear experience, or use systematic desensitization methods (such as repeated and gradual exposure from weak to strong under the guidance of a psychologist) to gradually reduce the sensitivity to the feared objects or situations, so that patients can gradually face the feared objects calmly and overcome their fear.

2. Rescue methods for people who faint with blood

Hemophobia itself is a type of vasovagal syncope, such as syncope caused by pain, tension, fear, fright and various traumas. Because these factors are common causes of stress. Generally, fainting due to blood is just a temporary loss of consciousness. The person is in a state of light coma, with physiological reflexes still present and vital signs stable, so there is no need to panic.

The patient should be laid flat and moved to a safe place with a suitable temperature. The buttons on the neck should be unbuttoned. If there are dentures, they can be removed. Foreign objects or sputum in the mouth should be cleared promptly. If conditions permit, low-flow oxygen should be administered. The patient should be patted on the shoulder and gently called. The patient will usually wake up naturally within a few minutes. It is recommended not to feed water to the patient to prevent choking and causing unnecessary trouble. Generally, the patient can recover after resting for 10-15 minutes. If necessary, emergency medication is needed.
