You went into the office yesterday, but you’re working from home today.
You walked around on your last outing, but you’re using a mobility aid this time.
You made it to dinner on Friday, but cancelled plans on Saturday.
You travelled last month, but this week even your usual routine feels like a lot.
From the outside, those things can look inconsistent.
When you live with a dynamic disability, they don’t necessarily contradict each other at all.
One of the harder things about changing capacity isn’t simply adapting to what your body can do. It’s living in a world that often expects yesterday’s capacity to predict today’s.
What does dynamic disability mean?
A dynamic disability is a disability where a person’s symptoms, functioning, support needs or capacity can change over time.
Those changes may happen across months or weeks, from one day to another, or even within the same day.
That can mean someone is able to do an activity at one point and needs support with it at another. They may use an accessibility tool sometimes but not always. They may have periods of greater capacity alongside periods when everyday activities require significantly more consideration.
The important part is this:
Being able to do something once doesn’t necessarily establish what someone can consistently do.
What you see doesn’t show you what something required
Seeing someone do something tells you that they did it.
It doesn’t tell you what it took.
Someone attending a wedding doesn’t show you how they prepared beforehand, what adaptations they made while there or what the following day looked like.
Seeing a colleague in the office doesn’t tell you whether commuting used most of the energy they had available that morning.
A photograph from a holiday tells you very little about the planning, accessibility arrangements, changed itineraries or downtime surrounding it.
This is one reason snapshots can be misleading when we make assumptions about disability.
Participation and ease are not the same thing.
Capacity isn’t a bank balance with a predictable number
It would certainly make planning easier if everyone woke up knowing precisely what they had available for the day.
Real life isn’t always that cooperative.
Capacity can be influenced by many factors, and the experience varies significantly between people and conditions. For someone with a dynamic disability, this can make apparently simple commitments surprisingly difficult to predict in advance.
A plan made two weeks ago may still be something you genuinely want to do when the day arrives.
Whether you’re able to do it in the same way you imagined is another question.
That isn’t necessarily unreliability.
Sometimes, it’s new information.
Using support sometimes doesn’t make it unnecessary
Dynamic disability can also challenge the way people think about accessibility.
We often expect disability supports to be permanent and visibly consistent.
But someone might use a cane on one outing and not another. They may request airport assistance for one journey and navigate independently on another. They might need an accommodation during one period at work and not need the same adjustment indefinitely.
The fact that a tool or accommodation isn’t needed every moment doesn’t make it unnecessary when it is needed.
Accessibility doesn’t have to pass a consistency test to be legitimate.
Good days don’t disprove difficult ones
This may be one of the strangest parts of having an illness or disability that changes.
A good day can sometimes be treated as evidence against the difficult ones.
But going out, working, laughing, travelling, getting dressed or doing something you enjoy doesn’t prove that previous limitations weren’t real.
And having a difficult day doesn’t erase everything you’re capable of either.
Both are pieces of a much larger life.
That matters because people with chronic illness shouldn’t have to hide the enjoyable or active parts of their lives simply to make their disability believable.
“You could do it before” isn’t always useful information
There are situations where previous experience genuinely helps us understand what might be possible.
But when capacity changes, “you did it last time” can become an expectation rather than useful information.
A more helpful question might be:
“What would work for you this time?”
That small shift leaves room for the person in front of you to answer based on their current circumstances rather than having to defend why something has changed.
The same principle can apply to friendships, relationships, workplaces, family plans and everyday life.
Consistency doesn’t have to mean doing the same thing every time
When your capacity changes, consistency may need a different definition.
It could mean consistently adapting.
Taking the train sometimes and driving another time.
Going for the whole event once and leaving early the next.
Working from the office when it works and using available flexibility when it doesn’t.
Travelling, but building more room into the itinerary.
Making the plan, while knowing you may need to change it.
The outcome doesn’t have to look identical for the intention behind it to remain the same.
A changing body can still belong to a full life
Dynamic disability can introduce uncertainty into everyday life.
But uncertainty doesn’t mean life has to become permanently smaller.
People with changing capacity still work, build careers, maintain relationships, travel, make plans, pursue interests, rest, change their minds and have ordinary Tuesdays that aren’t particularly profound at all.
Sometimes participating means doing something exactly as planned.
Sometimes it means adapting how you do it.
And sometimes it means deciding that today isn’t the day.
At Ìdẹ̀ra by Azzy, we’re interested in designing around that reality: people whose lives continue even when their needs aren’t identical every day.
As we prepare to launch, The Soothe Station is growing into a collection of complimentary resources, practical tools and lived perspectives for navigating everyday life alongside chronic illness.
The Soothe Station is exclusively available to members of our Comfort Circle. Join for free to access the growing collection and new resources as they’re added.
