Caring for Someone with Heart Failure
Heart failure means the heart isn't pumping blood around the body as effectively as it should — it doesn't mean the heart has stopped working, but that it's working less efficiently, often leading to fluid building up in the lungs, legs, or abdomen. It's a common long-term condition in older adults, and while it can't usually be cured, it can often be well managed with the right routine.
What to look out for
• Breathlessness, especially on exertion or when lying flat • Swelling in the ankles, legs, or abdomen • Fatigue and reduced ability to exercise • Rapid or irregular heartbeat • Sudden weight gain over a few days — this is often a sign of fluid retention, not a change in eating
Practical care at home
Daily weight checks are one of the most useful early-warning tools. A weight gain of around 2kg (roughly 4-5lb) over two to three days can signal fluid building up before other symptoms become obvious, and is often what prompts a medication adjustment before things become serious. Weighing at the same time each day, in similar clothing, gives the most useful comparison. Fluid and salt intake often need to be monitored, exactly as advised by the person's care team — this varies a lot person to person, so it's worth following their specific guidance rather than general assumptions. Medication timing and adherence really matter. Heart failure medications (diuretics especially) are often timed carefully — for example, earlier in the day to avoid disrupting sleep with frequent urination — and missed doses can allow fluid to build up quickly. Gentle activity is usually encouraged, not avoided. Within limits set by their care team, staying gently active tends to help rather than harm heart failure — but pacing and rest matter, similar to COPD. Sleep position sometimes needs adjusting. Some people find they need extra pillows or a slightly upright position to breathe comfortably at night as fluid redistributes when lying flat.
Why continuity of carer matters here specifically
Heart failure symptoms can worsen gradually over days, and the difference between "a bit more tired than usual" and "fluid building up and needs a medication review" is often only obvious to someone who knows the person's usual baseline. Daily weight tracking and noticing subtle changes both depend on a familiar carer being present consistently, not a different person each visit.
When to seek further help
Seek urgent medical help for sudden, severe breathlessness, chest pain, or fainting. Contact the GP or heart failure nurse promptly for rapid weight gain, increasing swelling, or breathlessness that's noticeably worse than the person's usual baseline — catching this early often avoids a hospital admission.
