Hypertension patients have low blood pressure in summer. Why?

The blood pressure of many hypertensive patients is relatively low in summer and high in winter, and some patients' blood pressure can be normal or near normal in summer. This is mainly because the change of temperature can affect the activity and function of human neuroendocrine system. In summer, the weather is hot, the peripheral blood vessels dilate, the peripheral resistance decreases, and the blood pressure decreases relatively; At the same time, excessive sweating, decreased blood volume, excessive sweating and excessive sodium excretion in summer will also cause blood pressure to drop. Eat more vegetables and fruits in summer than in winter. Vegetables and fruits are rich in potassium salt, which is beneficial to the control of blood pressure. Of course, everything is in two.

Hypertension is not high, and you can't stop taking medicine in most cases, except a few.

Hypertension is a chronic disease and usually cannot be cured. It needs to be controlled through long-term lifestyle adjustment and drug application. Therefore, in most cases, you need to take medicine for a long time and you can't stop taking it, otherwise the unstable blood pressure control will do great harm to your body. Controlling blood pressure in a stable range for a long time is to delay the progress of arteriosclerosis, avoid complications, improve the quality of life and minimize the incidence of death.

However, some patients have very good diet and exercise control. In some special periods, such as summer or when cerebrovascular complications are common, they can stop taking drugs appropriately. In other cases, it is not recommended to stop taking drugs.

Data expansion: What is hypertension?

Blood pressure is the lateral pressure exerted on the blood vessel wall when blood flows through the blood vessel. Systolic SBP is written on a diagonal line, which is generally called "high pressure", reflecting the pressure when the heart contracts. Below the diagonal line is written diastolic blood pressure DBP, which is called "low pressure" by ordinary people and reflects diastolic blood pressure. The unit of blood pressure measurement is mmHg. Hypertension means that the pressure in blood vessels continues to exceed the normal range. When our systolic blood pressure exceeds 140mmHg, or our diastolic blood pressure exceeds 90mmHg, we may have hypertension.

H type hypertension: Hypertension with elevated homocysteine is called H type hypertension. Hypertension complicated with homocysteine is one of the main risk factors of stroke in China.
