Big cause of difference in blood pressure of bilateral upper limbs

The reasons for the large difference in blood pressure of bilateral upper limbs include physiological changes, vascular diseases, neurological diseases, etc. The specific analysis is as follows:

1. Physiological changes

If the patient is sitting or standing for a long time, or performs strenuous exercise and emotional tension before measurement, it may affect the measurement results.

2. Vascular diseases

If the patient suffers from vascular diseases such as aortic dissection and arteriosclerosis, resulting in obstruction of blood flow, resulting in large difference in blood pressure of bilateral upper limbs after measurement.

3. Neurological diseases

If the patient has abnormal sympathetic nerve activity, cervical spondylosis, peripheral nerve diseases, etc., resulting in nerve damage, the above phenomenon can also be caused.
