Hypotensive dizziness is mainly caused by insufficient cerebral perfusion due to hypotension. Acute hypotension clinically often results in dizziness, black eyes, limb weakness, cold sweat, palpitations, oliguria and other symptoms due to ischemia of the brain, heart, kidneys and other important organs, and in severe cases, it manifests as syncope or shock. Chronic hypotension, somatic hypotension can be asymptomatic in mild cases, and in severe cases, mental fatigue, dizziness, headache, or even fainting. In postural hypotension, symptoms such as dizziness, lightheadedness, blurred vision, weakness, nausea, and cognitive dysfunction may occur after a change in position. The causes of hypotension can be divided into physiological hypotension, and pathological hypotension. Physiological hypotension is related to the individual’s constitution and has no significant effect on the patient. Secondary hypotension can be seen as a result of hemorrhage, acute myocardial infarction, severe trauma, and other causes that lead to a dramatic decrease in blood pressure.
