Three main themes emerged: "Experience with care demands," "Coping with care demands," and "Motivation for caregiving." Older adults with hypertension and/or diabetes mellitus had needs that placed a burden on informal caregivers' work life, health, and social life. Informal caregivers of older adults with hypertension and/or diabetes mellitus are under strain. Caregiving is a difficult task, requiring a lot of time, effort, attention, and devotion. Nurses should plan the care of older adults with hypertension and/or diabetes mellitus in collaboration with their informal caregivers.
