The short answer
Offer drinks the person likes in a familiar cup and at times that fit their day. Small, repeated offers can help, but do not force drinks or set a fluid target from a website. Ask a doctor about individual needs or new problems.
- Make a preferred drink easy to see and reach.
- Offer drinks during familiar routines without pressure.
- Do not restrict fluids to prevent toilet accidents unless a health professional has advised it.
- Ask a health professional about fluid needs, dehydration concerns or swallowing changes.

Someone living with dementia may forget to drink or may not notice thirst. A drink that is out of sight or hard to hold can also be easy to miss. Small changes to the routine can make drinks easier to accept while keeping the person in control.
The Alzheimer’s Association guidance on food and eating suggests offering small cups of fluid through the day and foods with water in them. Dementia Australia’s nutrition advice also recommends familiar drinks and easy access. This page gives general ideas, not a daily fluid target for a particular person.
How can I make a drink easier to notice and reach?
Put a drink the person likes where they can see and reach it. Use a familiar cup or bottle that feels comfortable to hold. If the person prefers a certain temperature, taste or cup, keep that in mind. One small choice may be easier than asking them to choose from many drinks.
Offer drinks as part of routines the person already knows, such as a meal, a rest or a visit outside. A small cup can feel less demanding than a large glass. Offer another drink later without turning it into a test or a reminder that the person forgot.
If the person can pour or carry a drink independently, let them. If they want help, ask before pouring or placing the cup in their hand. A new cup, straw or location may feel unfamiliar, so change one thing at a time and keep what works for the person.
For an outing, bring a drink the person likes and offer it during a rest or meal. If several people help, share the person’s preferred drink and cup with their agreement. Keep the drink within reach, but ask before moving it or handing it to them.
What drinks or foods can I offer?
Start with drinks the person enjoys and can take safely. Water is one option; milk, soup, smoothies or other familiar drinks may also fit their preferences and care plan. Some fruits and other foods contain water as well. The Alzheimer’s Association lists fruit, soup, milkshakes and smoothies among options with high water content.
There is no need to insist on one drink if the person refuses it. Offer another familiar choice or try later. Ask the person’s doctor or dietitian before changing their diet or drink plan, especially if the person already has medical instructions about fluids.
Should I restrict drinks to reduce toilet visits?
Do not reduce fluids to prevent accidents unless a health professional has given an individual plan. The Alzheimer’s Association warns that limiting fluids can cause dehydration and other problems. A person who needs help finding or using the bathroom may benefit from a different kind of support. Our continence guide covers toilet routines and privacy.
Spread offers through the day rather than asking the person to drink a lot at once. Follow any existing medical instructions and ask a doctor what amount is right for the person. Do not rely on a general online number; fluid needs vary, and some people have a medical fluid plan.
What changes should I notice?
Pay attention to what is different from the person’s usual pattern. They may drink much less than usual, leave a favorite drink untouched or need more help than before. A dry mouth, dizziness, unusual tiredness or changes in urination can also be reasons to check with a health professional. These signs can have other causes, so do not diagnose dehydration yourself.
Write down what you noticed and when. Include whether the person was ill, in a hot place or having trouble holding or swallowing a drink. The Alzheimer’s Association notes that signs of dehydration may be hard to spot in a person with dementia. If there is a sudden change or you are worried, contact a doctor or other health professional.
What if drinking has become difficult?
If the person coughs, chokes, holds food or drink in their mouth, or has a new difficulty swallowing, stop and ask a qualified health professional for advice. Do not thicken drinks, change food texture or try swallowing techniques unless a professional has recommended that plan for the person. Our mealtime guide covers what to do about new chewing or swallowing problems.
If the person has a dry mouth, sore teeth or dentures that feel uncomfortable, ask them what they notice and contact a dentist or doctor. Mouth pain can make drinking harder. See our oral-care guide for gentle ways to support mouth care.
Sudden confusion needs immediate medical help. The NHS guidance on sudden confusion advises people not to self-diagnose. Use local emergency services or the urgent-care process where you live.
How can I offer drinks without pressure?
Make the offer, then give the person time to decide. They may prefer to drink later or choose a different cup. Avoid correcting, bargaining or forcing a drink. If they often decline, check whether the drink is easy to reach, whether they like the taste and temperature, and whether the person is comfortable in the setting.
Ask the person what helps and share useful preferences with other helpers only if they agree. A familiar cup, a chosen place or a quiet moment may make drinking easier. If the concern continues, ask a doctor or dietitian for advice specific to the person.
The goal is to make drinks available in a way the person accepts. Offer gently, respect their choice and get professional advice when needs change.
Common questions
How can I encourage someone with dementia to drink more?
Offer a drink they enjoy in a familiar, easy-to-hold cup. Keep it within reach and make small offers during routines such as meals or a rest. Respect the person's choice and ask a health professional if intake remains a concern.
Should I limit drinks to reduce incontinence?
Do not restrict fluids to prevent accidents unless a health professional has given an individual plan. Too little fluid can lead to dehydration and other problems. Ask the person's doctor about their needs.
What signs might mean someone is dehydrated?
A dry mouth, dizziness, unusual tiredness or a change in urination may be signs, but they can have other causes. Contact a health professional if you are concerned, and seek immediate help for sudden confusion.
What if someone coughs or chokes when drinking?
Stop and contact a health professional for advice. Do not thicken drinks or change their texture unless a qualified professional has recommended it for that person.
