Bruising and Bleeding
Older adults may be more prone to easy bruising. As people age, the skin thins and people lose some of the protective layer of fat below the skin surface. So a minor bump is more likely to cause blood vessels to break, leading to bruising. Also, the small blood vessels themselves become less elastic and more fragile, leading to easier bruising. Older adults also are more likely to takeaspirin,clopidogrel,warfarin, or direct oral anticoagulants, which make bruising and bleeding more likely.
