Orthostatic hypotension is observed in 10 to 20% of all patients aged 65 or over. The elderly is thus at an elevated risk for orthostatic hypotension; however, the relative contributions of normal ageing, of diseases and their respective treatments to its development are unknown. Orthostatic hypotension discovered by chance in a symptomatic or asymptomatic elderly patient has to be considered as risk for falls or syncopes. The most common reversible causes are side effects of various drugs and hypovolemia. Next to a specific therapy of the underlying causes, symptomatic measures are proposed. Pharmacotherapy is limited to patients incapacitated by symptoms.
65岁及以上的所有患者中，10%至20%会出现直立性低血压。因此，老年人患直立性低血压的风险较高；然而，正常衰老、疾病及其各自治疗对其发生发展的相对作用尚不清楚。在有症状或无症状的老年患者中偶然发现的直立性低血压必须被视为跌倒或晕厥的风险因素。最常见的可逆转原因是各种药物的副作用和血容量不足。除了对潜在病因进行特定治疗外，还建议采取对症措施。药物治疗仅限于有症状的失能患者。
