Nobody can say how much somebody drank yesterday. Everybody can say what they drank out of, and how many times — and that count is reliably about half what the same person would have estimated.

One ordinary day, counted

Count a normal day rather than the best one. Use the containers that are actually used in the house — the tool converts them, so you never have to estimate a volume. Nothing is saved and nothing leaves the page.

Why it goes unnoticed until something breaks

• Thirst stops being a signal. With age the sensation blunts, so somebody can be seriously short of fluid without ever feeling thirsty. Waiting for somebody to ask for a drink is waiting for a mechanism that has switched off.
• Everybody's estimate is roughly double. Not from carelessness: half-finished cups, plates cleared quickly, and several people each seeing one drink each. The count is the only thing that survives that arithmetic.
• The first consequences look like other diagnoses. Confusion, a fall, constipation, a urine infection, sudden drowsiness, a rapid pulse. Each gets treated as itself, and the intake behind them is never counted.
• Protein disappears before calories do. An appetite that has shrunk keeps the toast and drops the meat, fish and eggs — and protein is what muscle, skin and healing run on, which is why frailty and pressure damage arrive together.
• The reach matters as much as the will. A drink out of reach, in a cup too heavy to lift when full, or with a lid nobody can get off, is not a drink. So is a jug left in the kitchen for somebody who does not go to the kitchen.
• Hospital and care settings make it worse before they make it better. Meals missed for tests, drinks placed on the wrong side, charts filled in from memory at the end of a shift. Asking what the chart actually says is a reasonable question with a specific answer.

The signs that matter more than the number

• Urine: how dark, how strong-smelling, how often. The most useful daily observation available, and the one nobody records. Dark and infrequent is the finding.
• New confusion or drowsiness. In an older person this is an early sign, not a late one, and it is a same-day call rather than something to watch for a week.
• Dry mouth, cracked lips, a tongue that looks furrowed. Worth looking at properly with a light, because a sore or thrushy mouth is also one of the commonest fixable reasons somebody has stopped eating.
• Dizziness on standing. Often blamed on the blood-pressure tablets alone, when the fluid and the tablets are doing it together.
• Constipation that has become the daily problem. It reduces appetite in its own right, which closes the loop: less fluid, more constipation, less eating.
• Weight, written down with a date. The slowest and most honest measure. A kilogram a month is not a small thing in somebody who weighs fifty.

Why somebody stops, which is usually fixable

• The mouth. Thrush, ulcers, a dry mouth from medicines, dentures that stopped fitting after weight loss, teeth that hurt. Look inside with a light; this is the single most rewarding thing to check.
• Medicines. A dozen common ones cause nausea, dry mouth, altered taste or a metallic mouth, and several suppress appetite outright. It is a fair question to ask which of the list could be doing it.
• Constipation, pain, breathlessness. All three make eating an effort somebody quietly gives up on. Breathlessness in particular makes chewing exhausting, and small frequent food is the answer rather than persuasion.
• Depression and grief. Extremely common after a bereavement or a move, frequently missed, and treatable. Appetite is often the first thing to go and the last thing to return.
• The practical. Nobody to eat with, a cooker they no longer trust themselves with, a shopping trip that stopped happening, food that arrives at a time nobody is hungry.
• Something new. Rapid loss, a swallowing problem, a change in bowel habit, pain, blood anywhere, or a lump: that is not a nutrition question yet and it needs looking at rather than fortifying.

What actually works, roughly in order of how little it asks

• Attach drinks to fixed points, not to thirst. Waking, each tablet round, each meal, the afternoon programme, bedtime. A drink attached to something that already happens is the only kind that survives a bad week.
• Make the container bigger rather than the day busier. The same number of drinks in a full-size mug instead of a small cup is a hundred millilitres a time, and nobody has to be persuaded of anything.
• Put it within reach, in something liftable. On the dominant side, at the chair they actually sit in, in a cup that can be lifted when full and opened by those hands. A lidded beaker is not a defeat.
• Count the things that are not obviously drinks. Soup, jelly, ice lollies, ice cream, milky puddings, watermelon. For somebody who refuses drinks, frozen and spoonable fluid often goes down when liquid will not.
• Fortify what is already served rather than serving more. Full-fat milk, cheese in the mash, cream in the soup, milk powder in a milky drink, butter on everything. Same plate, same appetite, more in it — and a smaller plate is eaten more often than a larger one.
• Small and often beats three meals. Five or six small occasions, protein at each one if possible, and never a plate that looks like a duty.

What people believe, and what is so

The drill: 16 situations

Sixteen ordinary days — the beaker on the wrong side of the chair, the plate that came back clean because somebody cleared it, the supplement drinks in the cupboard nobody liked, the man who says he drinks plenty. Most have a reassuring answer that leaves the count exactly where it is. Pick your move; every answer explains why.
