Low blood pressure depends on the situation. If it is physiological, you don't need to take medicine, but if it is pathological, it is mainly for the cause of disease. Physiological diseases often have a family genetic history, which does not require special treatment. For hypotension, it will not affect the function of the body's organs, and there is no obvious feeling, so there is no need to take medicine or treat it. However, if it is pathological, it is mainly to treat primary diseases, such as myocardial infarction and trauma, which must be actively treated. For patients with low blood pressure, if they are taking antihypertensive drugs at ordinary times, they must pay attention and try not to change their positions suddenly. For patients with malnutrition and hypotension, nutrition must be strengthened to avoid electrolyte disorder and take more calcium and magnesium. If hypotension is caused by shock, venous blood volume must be supplemented. In addition, dopamine was used to raise hypertension.
