Surgery Is Not Just Something That Happens to You
When you decide to have gastric sleeve surgery, the decision feels like your own. You do the research, you attend the consultations, you prepare. What is easy to underestimate is how much the surgery will affect the people around you – your partner, your family, your close friends. The changes are significant, and relationships do not always navigate them smoothly.
We had surgery together in March 2024 at Weight Loss Riga in Latvia, which gave us an unusual advantage. We were going through the same experience at the same time. We could be honest with each other about what was hard because we were both living it. Even then, we noticed ways the surgery changed how we interacted with each other, and we saw clearly how it affected relationships with the wider people in our lives. We want to be honest about both.
When Your Partner Has Not Had Surgery
For the majority of people going through bariatric surgery, their partner has not had it. That creates a particular dynamic. You are changing rapidly – your body, your relationship with food, your social habits, your energy levels, your confidence. Your partner is watching that change from the outside, and their own feelings about it can be complicated.
Some partners are completely supportive from the beginning and stay that way throughout. Others go through a period of struggling with the changes even when they want to be supportive. The most common issues we have heard about from the wider bariatric community include: feeling left behind when the surgery person’s social world expands; concern that a more confident partner might become unhappy in the relationship; jealousy of the attention and praise the weight-loss person receives; guilt about eating normally when their partner cannot; and, occasionally, a kind of grief for the shared habits and routines that centred on food.
These feelings are valid even when they are uncomfortable to acknowledge. The key is to name them rather than let them fester. A partner who says “I am really proud of you but I am struggling with how much has changed” is in a much better position than one who says nothing and lets resentment build.
Our Experience as a Couple
Having surgery together removed some of those dynamics but created others. We supported each other through recovery. We adapted to the new way of eating at the same time. We both had the experience of weight dropping quickly, clothes no longer fitting, people reacting differently to us. But we also had to navigate two people dealing with significant physical and emotional change simultaneously, with no one in the couple who was in a position of stability to hold the other up.
There were weeks in the first few months when we were both exhausted, both dealing with dietary restrictions, both processing our changing bodies, both managing social events that felt complicated. James hit a nutritional deficiency crisis at month eleven – fatigue, brain fog, cold intolerance – at a point when Kirsten was also managing a Crohn’s flare. Those weeks were genuinely hard. We got through them by being honest that we were both struggling rather than pretending one of us was fine.
What helped most was staying focused on the fact that we were on the same side. When the surgery brings two people closer to their own health and life, that is fundamentally a good thing for a relationship. But it requires communication, especially in the first year when so much is shifting.
Family Relationships
Family dynamics around weight loss can be unexpectedly complicated. Most family members are supportive and pleased. But you will almost certainly encounter at least one person whose reaction is more ambivalent.
Sometimes it is a family member who has also struggled with their weight for years and is facing their own feelings about why they have not done something similar. Sometimes it is someone whose way of showing love has always been through food, and who feels that your surgery is a rejection of that. Sometimes it is someone who simply does not understand what you have been through and frames the surgery as “the easy way out,” which it emphatically is not.
James encountered some of this from extended family in the first year. The response he found worked best was not to argue or justify, but to simply get on with living well and let the results speak over time. Most of the scepticism faded by the eighteen-month mark. People who had questioned the surgery were, by that point, watching him enter a bodybuilding competition. The conversation shifted.
Friendships That Change
Social friendships built around shared activities that centred on food and drink can feel under strain when you stop being a full participant in those activities. If your social life revolved around large restaurant meals, Friday night drinks, or takeaways in front of the television, those rituals change.
Some friendships absorb the change easily. Friends who value your company more than they value the shared activity will adapt. Others are more fragile. If the main thing you had in common was a particular lifestyle, the surgery can reveal that the friendship was thinner than it seemed.
This is not always the surgery’s fault. Sometimes it accelerates a natural drift. Sometimes it prompts people to reflect on their own health, which can bring up feelings they project onto you rather than deal with directly. The most useful thing you can do is stay warm, be available for connection in whatever form works for you, and not take it personally when a friendship shifts.
New Relationships Within the Bariatric Community
One of the things neither of us anticipated was how meaningful connections within the bariatric community would become. Meeting people who have been through the same experience, who understand the hair loss at month four, the stall at month three, the complicated feelings about loose skin, the protein-first approach at every meal – those connections are uniquely sustaining.
James has found this particularly valuable. There is a kind of shorthand in bariatric communities that does not exist elsewhere. You do not have to explain yourself. You do not have to justify the surgery. You do not have to manage anyone else’s feelings about what you are eating. You are just talking to people who get it.
Whether that is an online support group, a local bariatric community, or even just one other person who has been through the same experience, finding that connection is worth the effort.
Where We Are Two Years On
Two years after surgery, our relationship with each other is stronger than it was before. We are healthier, we are more active, we communicate better. The hard months in year one – the deficiency crisis, the Crohn’s complications, the times when we were both depleted – required us to be honest with each other in ways that strengthened the relationship rather than strained it.
The relationships with family and friends that needed adjusting have largely settled. The ones that did not survive were probably already fragile. The new connections within the bariatric community have enriched both of our lives in ways we did not expect.
Surgery changes you. It changes the people around you too. Going in with eyes open about that – and with the willingness to communicate honestly when things feel difficult – makes the difference between relationships that fracture and ones that deepen.

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.
