Fluctuating Blood Pressure: Causes, Treatment, And Prevention

Blood pressure fluctuating down and down is a serious medical problem, very difficult to control and hide the risks of health and human life.

1. How does blood pressure change in the vascular system?

Blood pressure is the pressure of blood vessels on artery walls. High blood pressure in the aorta. The farther away from the aorta the blood pressure in the heart decreases and the lowest in the vena cava.

Regulators of blood pressure index:

  • The force of contraction of the heart: the stronger the force of contraction of the heart, the higher the volume of squeeze, the increased blood volume increases the pressure on the vessel walls and blood pressure increases.
  • The larger the volume of blood in the heart, the higher the blood pressure. Therefore, the farther away the aorta is located in the position, the less blood is pumped so the blood pressure goes down.
  • The larger the area of ​​blood vessels, the lower the blood pressure. Therefore, when vasoconstriction, vascular cross section decreases, the pressure on the vascular wall increases, leading to increased blood pressure. In contrast, when vasodilation, vascular section increases, the pressure on the vascular wall decreases, causing blood pressure to drop. This is used in drug preparation to treat and control blood pressure.

2. What is unstable blood pressure?

Unstable blood pressure is a term used to describe a person's fluctuating blood pressure and this change may be sudden or persistent for a long time.

In fact, a person's blood pressure changes every day or even changes every hour. But this change is not much and acceptable.

Some causes of unstable blood pressure:

  • Sudden changes in blood pressure are very much related to emotions and psychological state. Anxiety, stress, fear or psychological shocks can cause blood pressure to skyrocket or fall quickly ..
  • Due to use of stimulants.
  • Due to sudden environmental changes or sudden posture changes.
  • Due to side effects of some drugs affect blood pressure such as misuse of blood pressure medication, corticosteroids ...
  • Unstable blood pressure can also be a complication or symptom of some diseases such as heart failure, neurological disorders, angina, high fever ...

The expression of unstable blood pressure is not always obvious but often signs such as:

  • Dizziness, dizziness and dizziness especially when changing positions or changing the environment suddenly.
  • Or tinnitus in the head.
  • Red face, heart palpitations or possible arrhythmias, may be accompanied by sweating.
  • Blood pressure index changes frequently and is difficult to control.
  • If prolonged unstable blood pressure status will cause cardiac arrhythmia, reduce the strength of the vascular wall and the risk of complications or heart attack is very high.

3. How to limit abnormal blood pressure?

In order to limit the unstable blood pressure, it is necessary to do the following:

  • Have a reasonable diet, healthy lifestyle.
  • Limit the use of stimulants such as alcohol, coffee, cigarettes ...
  • Avoid stress, stress and pressure at work.
  • Exercise regularly to improve health.
  • Monitor blood pressure regularly
  • Use treatment drugs in accordance with the instructions and indications of specialists.

The blood pressure is unstable, up and down erratically is difficult to control and if it persists without treatment it not only affects the heart but can also damage the kidneys, blood vessels and even is an eye that increases the risk of death for patients.
