Eating, drinking and swallowing

Meals can change a lot as dementia moves forward. A person may forget to eat, stop feeling hungry, or not know what to do with a fork. Later, chewing and swallowing can become hard. Eating less, drinking less and losing weight can then follow.^1,7

These changes are common, and many of them can be eased. This page explains why they happen, what helps at the table, the warning signs of a swallowing problem, and when to call the doctor or 911.

Why eating changes in dementia

Dementia affects the brain's control of hunger, memory, planning and movement. So the problem is often not the food itself. Common reasons include:^1,7,8

• Not feeling hungry. The brain may not send hunger signals, even when the body needs food.
• Forgetting. The person may not remember whether they ate. They may say they ate when they did not, or ask for lunch again right after lunch.
• Not recognizing food or tools. A white plate on a white table, or a busy pattern, can make food hard to see. A fork may no longer make sense.
• Too many choices. A full plate, a crowded table or a loud TV can be overwhelming.
• Changes in taste and smell. Old favorites may lose their appeal, and tastes can change suddenly.
• Mouth pain. Sore gums, a bad tooth or dentures that no longer fit can make chewing hurt. The person may not be able to tell you.
• Medicines. Some medicines lower appetite or cause dry mouth or constipation.¹¹
• Less activity. A person who moves less needs fewer calories.

Mood matters too. Depression and apathy can take away interest in food. Constipation is also common and can dull appetite. Tell the doctor if you notice either one.⁷

How eating changes by stage

Middle stage. Meals often get harder because of distractions, too many choices and changes in taste. Let the person do as much as they can on their own, and step in only when needed.¹ See middle-stage dementia.

Late stage. Chewing and swallowing problems become more common. They can lead to choking, weight loss and infections.^1,7 Many people need more help at each meal.² See late-stage dementia.

Making meals easier

Serve meals and snacks at about the same times each day.⁷ See building a daily routine and meals and nutrition.

Finger foods

When forks and spoons become hard to use, finger foods let a person keep feeding themselves. That protects dignity and independence.^1,7

Good finger foods are soft, bite-sized and easy to pick up. Examples include small sandwiches cut into pieces, chicken pieces, fish sticks, orange sections, and steamed broccoli or cauliflower.¹ Avoid foods that are hard to chew, such as raw carrots.¹

When weight drops

Some weight loss can happen as dementia advances. But it can also mean the person is not getting enough to eat, has another illness, or is having a medicine side effect. A doctor should check it.² Poor appetite and weight loss can also make behavior symptoms worse.¹

Ideas that may help:^1,7,8

• Offer 4 to 6 small meals instead of 2 or 3 big ones.
• Serve favorite foods, even if they are not the usual choice for that time of day.
• Add calories to foods the person already eats. Butter, gravy, cheese, whole milk, peanut butter or honey are some options.
• Try homemade smoothies or milkshakes. They add calories, protein and fluid in one cup.
• Encourage light activity, such as a short walk, which may boost appetite.
• Ask the doctor or a registered dietitian whether a nutrition drink between meals makes sense.

Note what the person eats and drinks for a few days, and weigh them weekly if you can. A behavior diary works well for this. Bring it to the next visit.

Drinking enough

Thirst fades with age, and dementia can make it fade further. Getting to the bathroom may also be harder, so some people drink less on purpose. Certain medicines can add to the problem.⁷ Low fluids can lead to dehydration (when the body does not have enough water).

To help a person drink more:^1,2,7

• Offer small cups of water or other drinks often through the day. Do not wait for them to ask.
• Use foods that are mostly water: soup, fruit, gelatin, sherbet, milkshakes and smoothies.
• Offer drinks they like, such as juice, milk or tea, and keep a cup in sight.

If worry about bladder accidents is a reason they drink less, see bladder and bowel problems for other ways to manage it.

Signs of dehydration include a dry or sticky mouth, peeing less, darker urine and headache. In more serious cases, a person may have very dark or no urine, dizziness, a fast heartbeat, sunken eyes, or new or worse confusion.⁹ Call the doctor the same day if you see early signs. Serious signs need care right away.

Swallowing problems (dysphagia)

Dysphagia (dis-FAY-jee-uh) means trouble swallowing. It is most common in older adults. It can happen with dementia, Parkinson's disease, stroke and other conditions that affect the brain and nerves.^3,4 See Parkinson's disease dementia.

How common is it? Studies report swallowing problems in anywhere from about 1 in 8 to more than half of people with dementia. The number depends on the stage and on where people live.⁵ One large review estimated it at about 7 in 10, but that number was very uncertain.¹²

When swallowing does not work well, food or liquid can go into the windpipe instead of the stomach. This is called aspiration. It can cause aspiration pneumonia (a lung infection from food, liquid or saliva getting into the lungs). Swallowing problems can also lead to choking, poor nutrition and not getting enough fluids.^3,12

Signs to watch for

No single sign proves a swallowing problem, but tell the doctor if you notice any of these:⁵

• Coughing or clearing the throat during or after eating or drinking
• A wet or gurgly voice after swallowing
• Food or liquid left in the mouth, or "pocketed" in the cheeks after a meal
• Drooling, or food or drink leaking from the lips or nose
• Chewing for a long time, or meals that take much longer than before
• Refusing or avoiding certain foods or drinks
• Weight loss or signs of dehydration
• Chest infections, pneumonia or fevers that keep coming back

Some people take food or drink into their lungs with no coughing at all. This is called silent aspiration.⁵ So repeated chest infections can be a clue even when meals seem fine.

Getting a swallowing check

Ask the doctor for a referral to a speech-language pathologist (SLP), also called a speech therapist. SLPs are trained to assess and treat swallowing problems.^3,5 They watch the person eat and drink. They may suggest a test that shows the swallow from the inside:^3,5

• A video X-ray swallow study (modified barium swallow), using food and drink that show up on X-ray.
• A scope test (FEES), where a thin, lighted tube lets the team watch the throat.

An SLP may suggest changes such as softer or chopped food, thicker drinks, or a better position for eating. Swallowing tricks with several steps may not work well with memory problems, so the SLP may focus on cues from the caregiver and on pacing instead.^3,5

Medicare Part B covers outpatient swallowing evaluation and therapy when a doctor or other qualified provider certifies the need. You usually pay 20% after the Part B deductible, as of October 2026.⁶ See what Medicare covers in dementia.

Safer eating day to day

These steps lower the risk of choking and aspiration. Check with the SLP first if the person already has a swallowing plan.

1. Sit upright. Seat the person straight up, with the head tipped slightly forward, for meals and snacks.^1,7
2. Stay upright after. Keep them sitting up for about 30 minutes after eating.²
3. Match the texture. Cut food into small pieces, or serve soft foods like scrambled eggs, oatmeal, applesauce, cottage cheese or well-cooked vegetables. Grind or purée food if needed.^1,7
4. Thicken drinks only if advised. Some people have trouble with thin drinks like water. If the SLP advises it, use a thickener as directed.^2,3
5. Go slowly. Offer small bites. Make sure each bite is swallowed before the next. Alternate bites of food with sips of drink.²
6. Give gentle reminders. Some people need a cue to chew or to swallow.⁷
7. Check the mouth after. Look for food left in the cheeks when the meal is over.^1,7
8. Keep the mouth clean. Brush teeth or clean dentures every day, and keep up regular dental visits.¹

Feeding tubes and late-stage care

In late-stage dementia, families are sometimes asked about a feeding tube. Research has not shown that tube feeding helps people with advanced dementia live longer, stay more comfortable, or avoid pneumonia or bedsores. It also has its own risks, such as infection, and some people need to be restrained so they do not pull the tube out.¹¹

Careful hand feeding is the usual alternative. Someone offers small bites of foods the person likes, slowly, while they sit upright.¹¹ Some weight loss is expected near the end of life.² Mouth care, ice chips or frozen juice can ease thirst.¹¹

These choices depend on the person's wishes and values. Read more in eating problems and feeding tubes at the end, comfort in the final months and hospice care for dementia. An advance directive written early can spare families hard guesses.

When to get help

Call 911 if the person:

• Is choking and cannot cough, speak or breathe¹⁰
• Passes out, has a seizure, or suddenly becomes much more confused or hard to wake⁹
• Has serious trouble breathing

Call the doctor soon if you notice:

• Weight loss without trying, or clothes getting loose
• Coughing, choking or a wet voice during meals
• Signs of dehydration, or fewer trips to the bathroom
• Mouth pain, a broken tooth, or dentures that no longer fit
• Less appetite after starting a new medicine⁸

Do not stop or change a medicine on your own. Talk with the doctor or pharmacist before changing anything. See managing medicines at home.

Helping someone eat, three times a day, can wear you down. See caregiver stress and burnout. If you are in crisis or thinking about harming yourself, call or text 988.

They say they already ate, but I know they didn't. What should I do?

Do not argue. Offer a small snack or drink, or sit and eat with them. A whiteboard note such as "Lunch done at 12:30" can help.

They refuse to eat. Should I push?

Pushing often makes refusal stronger. Stop, wait a little, and try again later with a favorite food. Look for causes like mouth pain, constipation, feeling unwell or a noisy room. See refusing baths, help or medicine.

Is it OK that they only want sweets?

Tastes often change in dementia. Adding a little sugar to food may help a person eat more.^1,2 If the person has diabetes, ask the doctor or a dietitian how to balance this.
