When an elderly person is not eating: causes, gentle help and when to worry

Written by James Frost, founder of Flaming Phoenix and the maker of Phoenix Bars. Updated October 2026.

Quick answer: When an elderly person stops eating, the cause is often something that can be eased: a sore mouth or loose dentures, a new medicine, low mood, eating alone, constipation or fading taste. Offer small portions of favourite food every 2 to 3 hours, eat with them and never force. Sudden confusion or drowsiness needs urgent medical help.

If you are watching a parent or relative push their plate away, the worry is understandable, and you are not overreacting by wanting to understand it. This page is for the family member or carer. It covers why older people stop eating, what you can check, how to help without pressure, when to get medical advice quickly, and what it means when eating less is part of the end of life. For what to cook, see my guides to meals for elderly people and high calorie foods for older adults. If you want something ready-made to leave within reach, a Phoenix Bar, which I make, carries up to 557 calories in a compact, 120g bar that can be offered a small piece at a time, or mixed with water or milk as a soft porridge if chewing is tiring.

Why do older people stop eating?

Appetite often softens with age, and on top of that baseline a few specific things commonly cut how much an older person eats. NI Direct says it is natural to start eating less as you get older, partly because you are less active. A 2015 review of appetite in later life by Pilgrim and colleagues in Nursing Older People estimates that 15% to 30% of older people have a marked fall in appetite, and lists the usual reasons: taste and smell fading, a dry mouth (about a third of people over 65 have reduced saliva, most often because of medicines), dentures and chewing difficulties, constipation, low mood, and living and eating alone.

The NHS says people aged 65 and over are particularly at risk of not eating enough, and lists a lack of interest in eating and drinking among the signs. So it is worth looking for the cause, because the help that works depends on it.

What can you check yourself?

The table is a carer's checklist, built from the NHS, British Dietetic Association and Pilgrim review guidance cited on this page. None of it needs medical training.

The drinks figure comes from the British Nutrition Foundation, which recommends six to eight drinks a day and notes that thirst can fade with age, so dehydration is easy to miss. The plate and finger-food tips come from the British Dietetic Association's food fact sheet for older adults, which also suggests getting dentures checked if they do not fit.

How do you help an elderly person eat more without pressure?

Offer small amounts often, make each one count, eat together and keep the table relaxed. Pushing an older person to eat, or turning a meal into a test, tends to backfire.

Small, regular offers

The NHS advice on supporting someone you care for with eating suggests small meals and snacks every 2 to 3 hours, and making mealtimes a social occasion by sitting down and eating together. A few spoonfuls on a side plate look manageable and can always be topped up; a heaped dinner plate can be off-putting before the first bite.

Make small amounts count

When someone will only manage a little, enrich what they already eat. The British Dietetic Association's fact sheet suggests a tablespoon (10g) of grated cheese on potatoes or vegetables, a tablespoon (15g) of dried skimmed milk powder stirred into custard, porridge or soup, or a tablespoon (15g) of nut butter in porridge. Favourites first: a familiar dish from years back is usually eaten more readily than something new. My guide to high calorie foods for older adults has the full list of easy additions, and protein for older adults explains why protein needs particular attention.

Keep drinks away from mealtimes

The NHS advises avoiding too many drinks just before meals when appetite is poor, while still making sure the person drinks through the day. A cup of tea half an hour after lunch does both jobs.

Make it easy

On tired days, choose soft food that needs no preparation: a yoghurt pot, a rice pudding, scrambled egg, or a few pieces of one of the high calorie bars I sell. If chewing is the problem, my guide to soft high calorie foods has easier options, and my guide on how to increase appetite covers the habits that help appetite come back.

When should you worry about an elderly person not eating?

Worry, and act, when the change is sudden, when weight is falling without trying, when they are not drinking, or when there are new signs such as confusion, drowsiness or trouble swallowing. A gradual drop in appetite over months is common in later life; a sudden change in someone who was eating normally until recently is different.

The table sets out what different situations can mean and what to do, based on the NHS guidance linked on this page.

The urgent advice on confusion is from the NHS page on sudden confusion. Once the cause is found and dealt with, appetite can come back.

When reduced eating is part of the end of life

Sometimes, when someone is very frail or in the last weeks of a serious illness, a fading interest in food and drink is part of the body slowing down. Marie Curie says it is normal for people to eat and drink less than usual, or not at all, in the last weeks, days or hours of life, and that they should not be forced. It also says that at this stage, how much someone eats and drinks will not change how long they live.

This is one of the hardest things for a family to watch, and the instinct to keep offering food is completely natural. At this point, gently offering small amounts of a favourite food or drink, without pressure, is kinder than pressing, and the focus shifts from nutrition to comfort. Marie Curie suggests small chips of ice or frozen juice to refresh a dry mouth, and asking the doctor or pharmacist about saliva sprays and gels. The team caring for the person, including the GP, district nurses or hospice staff, can explain what is happening and what helps.

For someone who wants to eat but can only manage a little

Where someone simply has a small appetite, the aim is to make the little they do eat carry more, and my guide to high calorie foods for older people lists easy foods that help. If you want something in the cupboard that needs no preparation, Phoenix Bars are one option: up to 557 calories in a compact, 120g bar, with up to 19g of protein, that can be broken into pieces to nibble across the day or stirred into milk as a soft porridge. It is an ordinary food offered alongside everyday meals, never something to press on anyone who does not want it. If a speech and language therapist has advised smooth food, see high calorie pureed foods instead.

Frequently asked questions

How do you get an elderly person to eat?

Gently, and without pressure. Offer small, attractive portions every 2 to 3 hours, lean on favourite foods, sit down and eat with them, and choose softer options if chewing is hard. Enrich what they do eat with a little cheese, butter, milk powder or nut butter, so a few mouthfuls carry more. A ready-made option, such as a Phoenix Bar, which I make, with up to 557 calories in a compact, 120g bar, can be left within reach for nibbling or mixed with water or milk as a soft porridge.

What should I do if an elderly person refuses to eat?

Do not argue or force it. Take the plate away calmly and offer something small again in an hour or two, ideally a favourite. Use the time to check the usual causes: mouth and dentures, medicines, bowels, drinks and mood. If the refusal carries on for more than a day or two, or comes with confusion or drowsiness, get medical advice.

Is loss of appetite normal in old age?

A gradual reduction is common, because older people tend to be less active and need less food; NI Direct calls eating less with age natural. A sudden or marked change, or weight loss that carries on, is different and worth raising with their GP.

How much should an elderly person drink if they are not eating much?

The British Nutrition Foundation recommends six to eight drinks a day for older people, and water, tea, coffee and fruit juice all count. Thirst can fade with age, so offer drinks regularly instead of waiting to be asked. Milky drinks between meals add nourishment as well as fluid; my guide to high calorie drinks has ideas.

How long can an elderly person go without eating?

There is no single figure that holds for everyone, because it depends on the person's overall health and whether they are still drinking. The question most often comes up when someone is very unwell, and at that stage the team caring for them, including hospice or palliative care staff, is the best source of guidance and support for the family.
