When encountering hypotension in summer, kidney friends should pay attention to the following aspects.

Recently, many hypertensive kidney friends say that their blood pressure is always unstable, and some people stare at blood pressure and take medicine. In summer, blood pressure is low or tends to normal range. Can I not take medicine?

The answer is no!

Summer is a season prone to blood pressure drop, so people need to pay special attention. So how to recognize the precautions for controlling blood pressure in summer?

Blood pressure fluctuates 24 hours a day and changes throughout the year. Blood pressure is generally lower in summer. This is due to excessive sweating in summer, increased water evaporation through the body surface, and increased loss of sodium salt affecting blood pressure. If the water supply is insufficient, it is equivalent to taking diuretic and antihypertensive drugs, and the blood volume is reduced, and the blood pressure is correspondingly reduced.

So how should kidney friends take antihypertensive drugs and manage hypotension in summer?

When the weather gets hot in summer, the blood vessels of the whole body will expand, and the blood pressure will be slightly lower than that in the cold winter. Everyone has individual differences. If the blood pressure fluctuates greatly in summer, and the blood pressure is lower than usual or normal, it is still necessary to continuously monitor the blood pressure changes closely, but it is generally not recommended to stop taking drugs suddenly.

No matter in summer or other seasons, even if blood pressure drops and improves, medication must be adjusted under the guidance of a doctor. Because high blood pressure requires long-term medication, if you stop taking drugs or reduce the amount rashly, this balance may be broken, leading to large fluctuations in blood pressure and danger.

The change of blood pressure is unpredictable to some extent and is greatly influenced by the outside world. Some hypertensive patients suddenly encounter some things, such as anger, poor sleep, overwork, noise, urinary tract infection and even a cold, which may lead to a sudden increase in blood pressure. Regular monitoring of blood pressure is to prevent this effect. Once the blood pressure fluctuates greatly, it is necessary to see a doctor in time and adjust the medicine.

Monitor blood pressure at home and find hypotension in time.

The blood pressure of human body fluctuates with physiological conditions such as exercise or sleep at any time. Everyone's blood pressure changes differently. Generally, it is the highest in the morning and the lowest at night, and some people can rise again at night, forming a small peak. Therefore, it should be tested several times a day at first, and once every morning and evening after the blood pressure is controlled normally.

There is a kind of hypertension that kidney friends need to know. Many kidney friends may have this experience. The blood pressure measured at home is not high, or even low. The blood pressure measured in the hospital is always higher than that at home, so they suspect that they are not accurate. In fact, the environment and state of the home and the clinic are different, and the blood pressure is naturally different. In most cases, the clinical blood pressure is higher than the blood pressure measured at home, which is called "white coat hypertension" or "white coat phenomenon".

Doctors mainly adjust drugs according to the results of self-testing blood pressure at home. Therefore, it is very important to measure blood pressure at home and record it.

There are also some friends who usually have low blood pressure and often feel dizzy in summer. After measuring their blood pressure, they found that their blood pressure was very low.

How to manage hypotension?

1. If hypotension occurs, the amount of salt can be appropriately increased, generally 2-6g. At the same time, drinking more water into the blood can increase the blood volume, thus improving blood pressure. For kidney friends who don't need water control, drink plenty of water.

2, strengthen physical exercise, improve the body's regulatory function. Physical exercise is good for both hypertension and hypotension.

3. In order to prevent fainting, patients with low blood pressure should pay attention not to move too fast and too hard. When standing up from a lying or sitting position, move slowly. Patients with micturition hypotension should also pay attention to it. It is best to hold solid things with your hands when urinating to prevent falling.

4. Drug therapy: under the guidance of doctors, antihypertensive drugs such as midodrine, ritalin and ephedrine, adenosine triphosphate, coenzyme A, vitamins B and C can be selected to improve the metabolic function of brain tissue.

In short, if a friend with hypertension has hypotension in summer, the use and increase or decrease of antihypertensive drugs should be carried out under the guidance of a doctor; The key is to self-test blood pressure at home, so as to find blood pressure fluctuation early and seek medical treatment, and monitor and adjust drugs under the guidance of doctors. For friends who have no hypertension but are prone to hypotension, in addition to adjusting their diet and daily life according to the above methods, if hypotension is serious, they should seek medical advice as soon as possible and take medicine under the guidance of a doctor.
