James Writing This One
This one is James writing, because it is something I experience personally and something I think is important to talk about honestly. Body dysmorphia – or more accurately, a distorted perception of your own body – affects a significant number of people after major weight loss, and it is not talked about nearly enough.
What It Actually Feels Like
After losing a large amount of weight, you would expect to look in the mirror and see someone smaller. Logically, you know you are. The clothes tell you so – I went from needing 4XL to wearing a small. The numbers on the scale confirm it. Everyone around me comments on the change.
And yet there are days – plenty of them – where I look in the mirror and still see what I used to see. The brain has a very long memory for what your body looked like, and it does not automatically update just because the physical reality has changed.
There are moments where I will reach for a larger size in a shop out of habit, or squeeze past someone expecting to need more room than I actually do, or avoid a space because I remember not fitting in it – and then realise none of that applies anymore. The body has changed; the mental map of it has not fully caught up.
Loose Skin and the Realistic Part
It is worth separating two things that can get conflated. Some of what I am aware of when I look in the mirror is dysmorphic distortion – seeing myself as larger than I am. Some of it is realistic awareness of loose skin, which is a genuine physical consequence of losing over twelve stone. I do carry loose skin, and surgery to address it is something I am working towards. The challenge is keeping those two things separate: the realistic awareness of something that exists and has a plan, versus the dysmorphic response that tells me the weight loss has not happened or does not count.
Progress Photos Help
Progress photos, taken regularly, have been one of the most grounding tools for me. Looking at a photo from eighteen months ago next to one from now makes the reality harder to deny than the mirror alone. The mirror is a single moment that the brain can distort; a side-by-side comparison is harder to argue with.
Talking about it – which is partly why I am writing this – also helps. Naming it as a known psychological phenomenon rather than a personal failing takes some of the power away from it.
If You Are Experiencing This
If you are post-op and still struggling to see the change in yourself, you are not imagining it and you are not being dramatic. It is a real and well-documented response to significant weight loss. The brain adapts more slowly than the body, and there is no simple fix for that – it takes time, deliberate reality-checking, and in some cases professional support.
What I can say from two years out is that it does improve. The distortion is less frequent and less severe than it was in year one. It has not disappeared, but it no longer dominates.

About this content
This blog is written by James and Kirsten, a couple from the UK who had gastric sleeve surgery together in March 2024.
We started this blog because we couldn't find any sources of content that details before surgery, the surgery and then life post surgery - so we decided to write one ourselves.
Everything on this site is based on our own experience and the research we have done along the way. It is not medical advice. Gastric sleeve surgery is a serious procedure and every patient's journey is different. Please always consult your own bariatric team or GP before making any decisions about your health or treatment.
Some posts on this site may contain featured or sponsored content, or affiliate links. Where this is the case, it will always be clearly stated at the top of the article. Our opinions are always our own.
