Standing beside someone on dialysis

Kidney failure is not a single bad day. It is a long, tiring, repetitive treatment that reorganises a life around a timetable, and most of what it costs happens where you cannot see it.

Understanding the shape of it will not fix it. But it will stop you misreading exhaustion as rejection, or a flat mood as ingratitude, and it will make you far more useful in a clinic room.

A standard in-centre haemodialysis schedule is about three sessions a week, roughly four hours each (NIDDK). Add travel, waiting, weighing, connecting and recovery, and a four hour session is often a six or seven hour day. Three of those a week is most of a part-time job that pays nothing.

Afterwards, many people describe feeling washed out, sometimes for a few hours and sometimes for the rest of the day. This tends to be worse when a lot of fluid has been taken off, and it usually eases over the first weeks. It is very common, and it is under-treated: feeling terrible after every session is not something anyone should quietly accept, because it is usually a signal that the prescription needs adjusting. Encourage them to say so at the unit.

In between sessions, fluid and potassium build up. The longest gap, the one across the weekend, is the hardest, and it is measurably the most dangerous interval. This is why a missed session matters so much more than a missed appointment.

If they have a fistula, the first few needlings can genuinely hurt. Most people say it gets much easier as the fistula toughens and as the staff learn their access. That is worth saying out loud to someone who is dreading Monday.

Depression is common and it is under-recognised. A systematic review found that when depression is properly assessed by interview, about 23% of people on dialysis have it, while about 39% score positively on symptom questionnaires (Palmer et al., Kidney International, 2013). The gap between those two numbers matters: the physical symptoms of kidney failure, tiredness, poor sleep, poor appetite and poor concentration, look exactly like the symptoms of depression. A high score is a reason to be assessed properly, not a diagnosis.

Depression is also linked to missed treatments, which closes a dangerous loop. If the person you care for is withdrawing, low, or starting to skip sessions, that is a clinical problem with a treatment, not a character flaw. Tell the unit.

Grief is normal here, and it is rarely named. People grieve the job, the independence, the spontaneity, the body that used to work. So, quietly, do the people beside them.

Sex and intimacy change too, and almost nobody raises it. Erectile dysfunction is the norm rather than the exception in kidney failure, affecting around 71% of men with end-stage kidney disease and around 79% of men on haemodialysis in one meta-analysis, and most of them are never treated (International Journal of Impotence Research, 2020). Causes include anaemia, medication side effects, hormones, depression, exhaustion and body image, and many of them are treatable. It is worth raising with the team. It is not a betrayal to want your relationship back.

Carer burden in dialysis is real and it is routinely under-acknowledged, especially where a partner is not only a partner but the person who sets up the machine, needles the access, or manages the exchanges at home (clinical guidance and patient-organisation material are consistent on this point).

You are allowed to be tired. You are allowed to be angry, and then guilty about being angry. You are allowed to want an afternoon that has nothing to do with kidneys. None of that makes you a worse person to have around, and pretending otherwise is how carers quietly break.
