In addition, many individuals over the age of 65 may feel dizzy, fall or pass out when they stand suddenly due to blood pressure that is suddenly too low. This condition, known as postural or orthostatic hypotension, poses a danger of fractures and other serious injury. This is especially a concern in frail older people who often suffer as well from thinning bones (osteoporosis). Therefore, many doctors now set a target of 140/90 mmHg, 150/80 mmHg, or 150/85 mmHg for older individuals. Blood pressure medications should be started slowly in older people and increased gradually, to avoid any sudden drop in blood pressure levels.
