Why is my systolic blood pressure very high while my diastolic blood pressure is very low?
Disease description:
I went to the pharmacy and had my blood pressure checked for free. The result showed a very high systolic pressure and a very low diastolic pressure. Could you please explain why this happens?

In medical terms, the condition where systolic blood pressure (the upper number) is high while diastolic blood pressure (the lower number) is low is commonly referred to as "increased pulse pressure." It is mainly characterized by a significant increase in systolic pressure, while the diastolic pressure remains relatively low. This condition may be caused by various factors:
1. Atherosclerosis: With aging or the influence of unhealthy lifestyle habits, arteries may gradually harden, leading to reduced vascular elasticity. In such cases, systolic pressure (the upper number) may rise, while diastolic pressure (the lower number) remains relatively low.
2. Aortic valve insufficiency: The aortic valve is an important heart valve. If it fails to close properly, some blood may flow backward during heart contraction, which can lead to a decrease in diastolic pressure.
3. Endocrine disorders: Conditions such as hyperthyroidism and pheochromocytoma can cause abnormal blood pressure.
4. Side effects of medications: Improper use of certain medications, such as antihypertensive drugs, may lead to excessively low diastolic pressure.
5. Physiological changes in the elderly: As people age, vascular elasticity naturally declines, making them more prone to increased pulse pressure.
If you have concerns, it is recommended to seek medical advice promptly.
