Orthostatic hypotension is considered as a sustained drop in systolic blood pressure (SBP) greater than or equal to 20 mm/Hg or a decrease in diastolic blood pressure (DBP) of 10 mm/Hg, after 3 minutes of changing from the supine to the upright position. Based on this, this study was proposed, the general objective of which was to determine the incidence of orthostatic hypotension in patients over 65 years of age, institutionalized in the Dr. Carlos Fragachan Geriatric Center and the San Vicente de Paúl Asylum in Ciudad Bolívar, during the period October 2023 - October 2024. The research design of this study is of a non-experimental descriptive type; The population subject of this research consisted of 116 elderly people from the Dr. Carlos Fragachan Geriatric Unit and San Vicente de Paúl Asylum in Ciudad Bolívar in the period from October 2023 to October 2024. To select the sample, the stratified sampling technique was used, because all the elements of the sample are proportional to their presence in the population, it was made up of 67 elderly people over 65 years of age from the Dr. Carlos Fragachan Geriatric Unit and San Vicente de Paúl Asylum. A work form was used as instruments for this research. After analyzing and evaluating the data obtained, we can conclude that in the sample of elderly people studied, the presence of orthostatic hypotension was determined. In most of the elderly, an increase in the arterial pulse of more or less 10 beats per minute was observed when changing from a supine to a standing position. Considering that in the population studied more than 50% of the elderly showed a significant decrease in both systolic and diastolic blood pressure when assuming a standing position; and that this constitutes an important risk factor for causing falls and syncope, which can have serious consequences in these elderly people such as
