The physiological changes that occur with ageing that can impair appetite include changes to the digestive system, hormonal changes, disease, pain, changes to the sense of smell, taste and vision and a decreased need for energy. Changes to the digestive system can contribute to declining appetite.
Due to the physical changes of getting older, it's often considered “normal” to eat less. A decrease in appetite can also be the result of naturally fluctuating hormonal levels. Older adults might make dietary adjustments with dentures or when taking medication to avoid certain side effects.
A reduction in appetite is one sign that someone may be in the last days of their life. They may no longer wish to eat or drink anything. This could be because they find the effort of eating or drinking to be too much. But it may also be because they have little or no need or desire for food or drink.
As a result of discontinuing eating, patients can die in as early as a few days. For most people, this period without food usually lasts about 10 days, but in rare instances, it can last several weeks.

Ageing, an inevitable process, is commonly measured by chronological age and, as a convention, a person aged 65 years or more is often referred to as 'elderly'.
People can go longer without eating than they can without drinking, but for someone who is bedridden, they will typically die within a few days to two weeks if they stop eating or drinking completely.
Regular exercise, socializing more during meals, certain medications, and other lifestyle changes are all safe and effective ways to increase your loved one's appetite.
A person with dementia may lose interest in food. They may refuse to eat it or may spit it out. The person may become angry or agitated, or behave in a challenging way during mealtimes. If a person isn't eating enough, it can lead to weight loss and less muscle strength.
Australia's older generation (those aged 65 and over) continues to grow in number and as a share of the population. The ageing of the population creates both pressures and opportunities for Australia's health and welfare sectors.
Older adults need about the same amount of sleep as all adults—7 to 9 hours each night. But, older people tend to go to sleep earlier and get up earlier than they did when they were younger.
Age, Life Cycle and Evaluations of Personal Life
Fully 71% of those under age 50 expect their lives to be better in 10 years than they are today, as do 46% of those ages 50-64. By contrast, only about a fifth of adults ages 75 and older (19%) expect their lives to be better in the future than they are today.
Elderly dietary problems can be caused by a number of different factors: lack of interest in food due to changing taste buds, depression, or loneliness; lack of energy to cook; loss of appetite due to health conditions; and medication side effects, to name just a few.
According to their internal body clock, most older adults need to go to sleep around 7 p.m. or 8 p.m. and wake up at 3 a.m. or 4 a.m. Many people fight their natural inclination to sleep and choose to go to bed several hours later instead.
Older people wake up an average of 3 or 4 times each night. They are also more aware of being awake. Older people wake up more often because they spend less time deep sleep. Other causes include needing to get up and urinate (nocturia), anxiety, and discomfort or pain from long-term (chronic) illnesses.
Boredom, depression, chronic pain and/or nutritional deficiencies can be some of the underlying causes that account for excessive daytime sleeping. Medications can also be a problem.
Given changes in remaining life expectancy over time, age 70 can be thought of as the new age 65; initially, age 70 also appears to be the new 65 (or even younger) in terms of health.
Typically, the elderly has been defined as the chronological age of 65 or older. People from 65 to 74 years old are usually considered early elderly, while those over 75 years old are referred to as late elderly.
At 30 June 2020, Tasmania (20%) had the highest proportion of its population aged 65 and over, followed by South Australia (19%) and New South Wales (17%).
In the end stages of dementia (in the last few months or weeks of life), the person's food and fluid intake tends to decrease slowly over time. The body adjusts to this slowing down process and the reduced intake.
One of the most important daily caregiving tasks during late-stage Alzheimer's is monitoring eating. As a person becomes less active, he or she will require less food. But, a person in this stage of the disease also may forget to eat or lose his or her appetite.
