Fluid intake log
Add drinks consumed during one day. The tool totals millilitres and does not invent a personal target.
No clinical prescription. Fluid needs and restrictions can change with kidney or heart conditions, pregnancy, breastfeeding, medicines, fever, vomiting, diarrhoea, heat and activity. Follow advice from your own qualified care team. Seek urgent help for confusion, fainting, inability to keep fluids down, severe weakness, breathing difficulty or very little urine.
Daily log summary
Add drink entries to total the day.
What this tool does
It adds the quantities you enter. If—and only if—you enter a target already provided by your clinician, it shows the arithmetic difference. It does not estimate a need from body weight, prescribe extra water, or tell you to ignore thirst, symptoms or fluid restrictions.
