What to Wear to Dialysis: A Practical Guide

Nobody warns you about the temperature. You show up for your first session in whatever you had on, and about ninety minutes in you understand why everyone else brought a blanket.

Dialysis units run cold on purpose. The machines generate heat, and returning blood slightly below body temperature helps keep blood pressure stable during treatment. That is a clinical decision made for good reasons, and it means you are going to be sitting still in a cold room for hours.

Sleeves are the whole problem

If you have a fistula or a graft in your arm, your nurse needs to reach it, clean it and cannula it without a sleeve in the way. If you have a chest catheter, they need to get to your upper chest instead.

This is the thing that rules out most of your wardrobe. A warm jumper you have to take off entirely is worse than a light one that opens. What people land on, mostly:

• Short sleeves under a layer you can remove — the most common setup, and the reason a lot of people end up wearing a t-shirt to every session regardless of the season
• Sleeves that push up past the elbow and stay there, rather than sliding back down over the site
• Front-opening layers if your access is a chest catheter, so you are not pulling anything over your head with a line in
• Nothing tight over the access arm — no compression sleeves, no elastic cuffs sitting on the site

Adaptive clothing exists for this, with zips positioned over the access. It is genuinely useful and worth knowing about. Plenty of people also just wear a soft t-shirt and bring a blanket, and that is a completely reasonable answer.

Bring your own blanket

Most units have blankets. Most units also have a lot of patients and a finite number of blankets, and clinic blankets are thin. Almost everyone who has been doing this a while brings their own.

Same logic for socks. Your feet get cold before the rest of you does, and you are not walking around to warm them up.

The four-hour comfort problem

You are in one chair, mostly one position, for the length of a long film. Anything that digs in at minute ten is unbearable by minute two hundred. Waistbands, seams, stiff denim, anything with a hard fastening at the back.

The other thing people mention is that they get weighed before and after every session, and the number matters clinically. Wearing roughly the same weight of clothing each time makes that comparison cleaner. Some people keep a specific set of dialysis clothes for exactly this reason.

It is allowed to be something you like

There is a version of this where everything becomes medical. Medical clothing, medical schedule, medical vocabulary. A lot of people push back on that in small ways, and what they wear is one of the easiest places to do it.

A soft shirt you actually chose is not a small thing when you are spending twelve hours a week in it.

We make shirts, not medical decisions. Everything here is what people describe living through, not advice — your care team knows your access, your labs and your schedule, and they are the ones to ask.
