I'm having a gastric bypass when I weigh 9 stone

Hi all,

first time posting my own thread so apologies if this is wrong.

just looking for some advice really and some reassurance to anybody who's had a gastric bypass. Yes, im 9 stone, 5'5 and already slim.
I have a very complex medical history including an incurable cancer which is currently stable and lots more. Due to the cancer and chemo and many many surgeries I have had, I found out today that when I eat to about 40% of my stomachs capacity, the other 60% of my stomach flips / folds down. I'm under my oncology team who include gastro surgeons and had a Bavarium swallow today to find out why I'm being sick every single day after every meal. I have something called a gastric volvulus. Normally it's urgent or an emergency but my stomach flips back again after I've been sick or after my stomach has emptied into my intestines / bowel.

im on the list for surgery and the treatment is cutting away the bit of stomach that flaps. Roughly 60% of it. Essentially a gastric bypass.

has anyone here had a bypass? I am worried about losing more weight when I'm slim already.

AIBU to think, as much as this needs sorting, that a gastric bypass on a 9 stone slim woman is insanity?! I trust the consultants and realise this is the only way to fix it, but I am really worried. Its a small surgery compared to the huge surgeries I've had but I'm terrified!

if anyone has any experience or clarity on what the recovery is like, please please please could you reply, I'm so nervous.

thank you

I don't know anything more than anyone else about this surgery, but I can relate to struggling to keep your weight up. I'd also be worried in those circumstances.

I imagine you'll get your appetite back more when you aren't being sick all the time? That must put you off eating to some extent?

I wonder if medical cannabis could help for a bit. It'll massively increase your appetite. If I were in your position, I'd try and get a vape of it, because I know it would make me eat more. Being underweight is such a strain and it makes you so tired. It sort of begets itself after a while too, because you haven't the energy to eat.

My MIL had part of her stomach removed for the same reason OP but hers was a medical emergency. She was unwell for a while, constantly throwing up etc, and then collapsed in work one day and then was rushed into hospital where they removed a massive amount of her bowel. She remained in hospital for four months afterwards.

She is much ‘better’ now but she is tiny. She weighs 6 stone, but she was a slim woman before it and is short too. For a while afterwards she was fed via an NG tube in her nose and then they switched it to a g-tube right into her stomach. She actually did very well on this and gained weight but she had complications and it had to be removed. They tried it again but the same complications happened.

Currently she is just receiving nutrition by feeding herself. She gets full very fast though but refuses to take anything like fortisip as she doesn’t like it so she is her own worst enemy.

The throwing up has mostly stopped, she does have a lot of other conditions too. I feel like she would be much better if she actually looked after herself but she doesn’t and refuses any help. You need to remember you will be full very, very easily so focus on nutrient and calorie dense foods.

So sorry to hear about everything you’ve been through. I can see you are getting some answers from people who have had comparable experiences and I think the picture we are getting is that half of the battle is going to be finding how you can get the calories you need in future.

I realise you’ve only just had this news and you are reeling, but I did want to say that it sounds as if you’ve become a bit used to the way things are now. I think you will feel so much better if they can stop the vomiting and other unpleasant effects. So maybe this is going to be a really good thing for you? Being able to eat nice things without worrying about throwing up, and managing to take in enough calories to feel stronger.

ChoccieCornflake · 08/05/2025 15:06

It's definitely not an insanity if it's medically recommended. I would also imagine you will find it easier to retain weight with a small-but functioning stomach rather than a constantly vomiting one. Best wishes it all goes well with a speedy recovery and that you soon can eat much more easily

I was just about to say exactly the same. You'll probably have to move to small meals with snacks in between, but it sounds better than your current situation.

Good luck with the op!

BobbyBiscuits · 08/05/2025 16:30

My mum had a lower GI volvulus and it can be fatal if not fixed. If you are in need of surgery then of course you should have it.
I thought you were saying you were having it because you thought you were obese and had body dysmorphophobia/ED.
I'm sorry you've had to go through these health problems and wish you well.

evilharpy · 08/05/2025 16:28

God you poor thing, you really have been through the wars. I have no experience of any of this but just really wanted to wish you well, I hope it's all very straightforward and you make a quick recovery.

Studyunder · 08/05/2025 16:26

The main point I take from your original post is you can’t retain your food in order to nourish your body (which is going through a horrific time). The only solution is to get your nutritional requirements somehow.
It’s an extreme concept but this would allow your body to achieve what it needs to survive.
Gastric surgery is far more advanced than it used to be. Yes your stomach would be smaller, but you’d eat little and often to maintain your weight. I would imagine some initial weight loss while you adjust but at a slim 9 stone, you still have some spare reserves. The alternative would surely be bleaker. Continued sickness would cause further damage to your stomach, oesophageal system, teeth etc.
I know someone who have a gastric band and after initial weight loss, they’re now back to the same size as were prior to the surgery.
I can’t even begin to imagine what you’ve gone through so far. Discuss all your concerns with the medical team. At the end of the day, this is your decision to make. However, if this is what the experts have suggested, I would think this is the best option.
Sending you the kindness thoughts and love possible. You got this ❤️

Yes, it sounds like a sleeve gastrectomy instead of a bypass. This is the best diagram I could find showing the differences. The gastrectomy is much less invasive and sounds like a very good solution in your case.

Isobel201 · 08/05/2025 16:16

A gastric by pass is just really a medical procedure, the reasons for it can be many but the most popular is because it helps with obesity. If you need it, then that's fine x

Anotherdayanotherscan · 08/05/2025 16:12

The alternative would likely be tpn feeding which is grim, puts you at risk of infections and means you wouldn't eat anything. I would like to see if they are able to supplement your diet in some way and how they plan to do this. I hope you hear something positive soon!

Well they can get that extra info from taking 20 seconds to read the post. A title is the basic facts and the opening post is context.

If people weigh in based on the title without even reading OPs post then that's on them!

Edited

The point wasn't that people would "weigh in" without reading 🙄 it was that they wouldn't even engage with the post in the first place.

OP if your medical team have decided it's the right thing for you you could seek another medical opinion but I'm not sure how much value non qualified opinions are going to be for you. Obvs if there's someone who's gone through the same experience their input would be a useful addition.

EmeraldShamrock000 · 08/05/2025 15:59

I am sorry I don't have any experience, wishing you luck. 🌹

EquinoxQueen · 08/05/2025 15:55

Not read everything, but it’s not a gastric bypass. A gastric bypass is in two parts - reduction of the stomach pouch and bypassing the intestine by various lengths. The reduction in the pouch will make you feel fuller quicker but you won’t have the malabsorption associated with the bypass section.

you may lose some weight but not in the same way or for the same reasons.

MyDeftDuck · 08/05/2025 15:43

I know absolutely nothing about gastric surgery but I simply couldn’t scroll past without wishing all the best for your forthcoming treatment 💐

QueenKong101 · 08/05/2025 15:43

Not the same situation, but I've just had surgery to repair a giant hiatus hernia and am currently on a very soft food diet. Although I'd previously been trying to lose weight using WLI, having reached goal weight I was very worried about dropping any more and becoming underweight.

I'm pleased to say that despite not being able to eat much right now, I'm maintaining my weight OK so far - in part I'd guess due to reduced physical activity as I recover.

If you're OK with dairy then I'm finding full fat milk smoothies with nut butter, bananas, honey, oats and full fat Greek yoghurt are really helpful to keep calories and protein higher without taxing my stomach too much as it recovers. My gastric surgeon was keen for me to move up from just liquids to soft foods (mashed potato, soft pasta, stewed meat) within a few days of the op, giving me more options - hopefully yours will be the same. Good luck!

Hdjdb42 · 08/05/2025 15:29

I feel like it would be better to have a smaller fully functioning stomach as opposed to one that doesn't work and makes you vomit after most meals. I'd drink cream based coffees/drinks/soups to maintain your weight. I'm sorry this is happening to you, take care.

A sleeve is when they remove a portion of your stomach so it does sound like that's what you'll be having.

I have lost 8 stone with a sleeve so I can understand your worry. Yes, you will be on a liquid diet for a bit but I know there are very calorie dense drinks which could be more suitable for you to keep your calories high. When on a normal diet then you'd probably have to try to eat calorie dense food in small amounts which will be easy enough. I think that yes, you will lose weight to begin with but as I've seen in the gastric surgery community, a lot of people do put the weight back on so it can be done purposely if needed.

Sorry you're having all this trouble. It sounds like one thing after another but hopefully the surgery helps in the long run x

Thank you, this is really helpful. Congratulations on the weight loss too, that's a huge amount! Amazing x

I had a gastric sleeve when I was at goal weight (10.5 st).
While I eat less, the weight hasn't fallen off, and I still need to watch what I'm eating to manage my weight.

Everything is fine, although sometimes I do miss being able to eat a full meal, esp when out with friends.

NeverDropYourMooncup · 08/05/2025 15:18

As it's removing the useless section that isn't doing anything other than present a risk to you anyway, it's not as much a bypass as a getting rid of a problem. So you should be able to to eat more normally without that happening. I'd try and look at it as purely coincidental that the same procedure happens to achieve two aims - like a lens transplant can be to avoid wearing glasses and also restore sight to somebody with cataracts or a medication originally intended to treat cancer turns out to be brilliant for treating automimmune diseases.

The advantage of all those thousands of operations is that there is a wealth of expertise in performing them and information about how to ensure that you get adequate nutrition afterwards - and it's probably significantly lower risk/higher chance of success compared to those from undergoing surgery whilst morbidly obese.

It is really important to discuss this with your clinical team, but i would also ask for nutritional support post surgery.

Not me, and not bypass, but someone I knew has issues following surgery for cancer and was even slimmer than you are to start with. They have been given a specialist diet to follow which includes calorie dense food and been well on this for over 10 years. In their case it was all about managing their calorie intake rather than volume of food.

That's really good to know, thank you. I will absolutely ask for nutritional support leading up to and after.

The other thing to remember is this - you've had cancer and chemo and got through them. This is just routine surgery (to the people doing it, which is what counts). You can do this!!

Thank you ❤️❤️

That sounds more to me like a gastric sleeve and that's a very different procedure to a bypass x

I don't know anything about any of the weight loss surgeries, I know there are a few different types. What does a sleeve entail compared to a bypass?
is it an easier surgery? (I hope so!)

I’m guessing it’s the lesser of two evils. You may have a smaller stomach but at least you’ll be able to retain the contents. Versus retaining nothing and loses masses of weight. How have you been able to stay 9 stone with after each meal? Is it a recent thing?

All the best, fingers crossed for a smooth procedure and recovery.

I'm on a low dose of mirtazapine to help with my appetite. I don't vomit up the whole contents of my meals but a good portion of it. I also have 3 meal replacement shakes each day. I guess because I'm small perhaps I don't need an awful lot to maintain. If I don't have enough for a few days I will lose weight quickly which is my worry :(
