Low blood pressure has the potential to cause dizziness symptoms, and low blood pressure often causes target organ hypoperfusion with corresponding symptoms. For cerebrovascular hypoperfusion, symptoms such as dizziness, headache, and even hemiparesis and aphasia often occur, while cardiovascular hypoperfusion often results in symptoms such as angina pectoris and myocardial infarction, and renal hypoperfusion often results in oliguria, anuria, and even renal insufficiency, leading to uremia. Arterial hypoperfusion in the lower extremities can cause the occurrence of symptoms such as intermittent claudication. Low blood pressure can be seen in physiological hypotension as well as pathological hypotension. For pathological hypotension, treatment is needed to address the primary cause, and if necessary, vasoactive drugs are used to elevate blood pressure.
