How to treat low blood pressure depends on the extent of the decrease in blood pressure and the causes of low blood pressure. If the blood pressure is not too low and there are no obvious clinical symptoms, generally, there is no need for pharmacological treatment. What is needed is lifestyle adjustments, consuming high-nutrient foods, proper exercise, increasing the vitality of the heart and the elasticity of the blood vessels, and drinking more broth. If it is caused by severe illness leading to shock, immediate effective medication treatment and rescue are required, starting with the replenishment of blood volume, improving microcirculation, and using vasopressors to raise the blood pressure to a safe range, to ensure the blood supply to the heart, brain, and kidneys.
