Introduction

In general, physiological reflex syncope can be cured. Physiological reflex syncope is caused by transient cerebral hypoperfusion due to changes in body position, such as suddenly standing up from a lying or sitting position, and is related to autonomic nervous system regulation. It is usually not associated with organic lesions. Therefore, sudden standing up or prolonged standing in one place should be avoided.

Generally, reflex syncope is curable. The detailed explanation is as follows:

Reflex syncope is caused by transient cerebral hypoperfusion due to postural changes, such as suddenly standing up from a lying or sitting position, and is related to autonomic nervous system regulation. It typically is not associated with organic diseases. Therefore, avoiding sudden standing or prolonged standing still, especially under conditions of hunger, fatigue, or hot weather, can help reduce the occurrence of syncope.

Gradually increasing the time and speed of changing positions from lying down to standing can enhance the body's adaptability to these positional changes. This helps reduce blood pressure drops caused by abrupt postural changes and thus prevents syncope. Adjusting dietary habits, increasing salt intake, and enhancing blood volume are beneficial for maintaining normal blood pressure levels and reducing the likelihood of syncope due to cerebral hypoperfusion.

Lifestyle modifications should be the primary treatment for reflex syncope, and regular evaluation of the patient's condition is necessary to adjust the treatment plan timely. With comprehensive treatment measures, most patients can effectively prevent and control episodes of syncope, thus achieving a cure.
