What are the causes of low blood pressure?

Many people do not understand why low blood pressure occurs. In fact, people with heart disease, such as myocardial infarction or aortic stenosis, and hypothyroidism are likely to show symptoms of low blood pressure.

1. Heart disease

Suffering from heart failure, myocardial infarction, and aortic valvular stenosis will affect the heart's function of pumping blood, reducing the amount of blood delivered by the heart, leading to circulatory disorders and causing hypotension.

2. Peripheral vasodilation

When bacteria or toxins invade the peripheral blood vessels, the blood vessels lose their contraction function, leading to vasodilation and a drop in blood pressure, resulting in circulatory hypotension.

3. Temporary heavy blood loss

Due to heavy bleeding from surgery or trauma, the amount of blood circulating in the body decreases suddenly, causing temporary hypotension.

4. Hypothyroidism

When the thyroid function is weakened, symptoms such as loss of strength, physical and mental fatigue, chills, dry skin, etc. may occur, causing endocrine-induced hypotension.

5. Addison's disease

Suffering from this disease will affect the secretion of adrenocortical hormone, causing the patient to experience symptoms such as darkening of the skin, nausea, vomiting and low blood pressure.
