In 2007–2009, the most frequently occurring conditions among older people in the United States were uncontrolled hypertension (34%), arthritis (50%), and heart disease (32%). [52] Chronic mucus hypersecretion (CMH), defined as "coughing and bringing up sputum", is a common respiratory symptom in elderly people. [53]
These physical changes can be considered when assessing why an older person might not be getting the nutrition they need. As taste buds change with age, certain foods might not be seen as appetizing.
