I am struggling to find any nutrition that works after my bypass

I had a bypass of my duodenum, and I’m finding it really hard to get nutrition that my body will tolerate.

I log everything I eat and drink, plus sickness, toilet changes and sleep, and some clear patterns are showing up:

  • Fats seem to trigger bile and I end up vomiting.
  • Dairy makes me vomit too, I think because of the fat content.
  • Fortisip drinks are too high in carbs, sugar and dairy for me. I dump, then fall asleep for 2–3 hours afterwards.

So the things that are meant to help me get calories in are the things making me ill, and I can’t find anything that works.

Has anyone dealt with something similar? What did you find that you could actually keep down: drinks, foods, ways of eating, anything? And did your dietitian or team suggest alternatives that helped?

Thanks for reading. Any experiences would really help.

So my gastric band migrated……

The dark part of the image is the band. Had the band put in around 30 years ago, stopped working 20 years ago and now I know why. It migrated to inside my stomach and has adhered to the wall. Emergency surgery to remove it is in six days time. Been told this is very rare and I can’t find anyone else who this has happened to. I’m very anxious. Surgeon will try to remove it endoscopically and failing that they will open me up for removal. I have no idea what to expect afterwards. I’m 62 and live alone. Has anyone heard of this happening? Has anyone experienced this? I’d love to hear from you. Thanks for reading.

Little to no weight loss

Hi guys! This is my second surgery. I went from being sleeved to bypass because of weight gain and acid reflux. I'm feeling a little discouraged I'm only a month and a few weeks out but I am maintaining the same weight. I get my water in and I'm trying to reach my protein goals daily but I have no appetite. Any insights on what I'm doing wrong? TIA

Non scale victory!

I completed my first half marathon yesterday! 18 months ago I couldn’t even run one block. My weight has changed of course but more than anything I am grateful for this new life. I always felt like an active person trapped in a body that wouldn’t allow me to do the things I dreamed of. I’ve come so far and my life is so completely transformed!

Odd NSVs

What are the oddest non-scale victories you’ve encountered?

I‘ll start.

I can now pick up after my parents dog without gagging, not to mention the bending over. It took all I had to accomplish the task before surgery.

My mattress will likely be replaced this week. It’s only 9+ years old and sinking in the middle, but can only be rotated and not flipped. The weight that thing has endured …

Bucket list item #1 complete!

This is a success story post to give those of you that are thinking about surgery or are just starting some reassurance that you're making the right decision.

I'm almost 50 years old. Since I was little I've always been a flight enthusiast. I always wanted to fly a plane on my own. Flying a plane has been the number one item on my bucket list as long as I can remember. Growing up, I never had the time or money to do it. By the time I was an adult, I was too big to fit into the cockpit of a small plane. When I made the decision to have surgery, I told myself if I was ever able to lose the weight, I'd do it. Well, it happened. It's been almost two years since surgery. Hit my goal weight close to a year ago and have been able to keep it off. Over the weekend I went on my first "discovery flight". It exceeded my expectations. I was familiar enough with flight and this particular plane from being such a flight nerd that they let me do more on my own than they normally would during a discovery flight. The instructor let me taxi to the runway, line up, and takeoff on my own! Did some sightseeing and I was able to perform several maneuvers in the air with supervision. High g turns, wingovers, and even intentional stall and recovery. They also let me do some stuff on the ground that sounds boring but I loved it. Helped with the initial walkaround and startup checklists, Taxi'd to the fuel pumps and fueled the plane up on my own. Taxi'd back to the hangar after landing and did all the shutdown stuff. It was an absolute blast. Most fun I've ever had in my life.

None of that would have been possible had I not chosen to move forward with surgery. No regrets except that I didn't do it 20 years ago. I now get to live my life the way I want instead of being held captive by my weight. So can you!

Protein & Weight Loss

Currently remodeling my kitchen and as a result haven't been able to cook meals. I've had no appetite and am only doing like 450 calories a day. But being unable to cook my protein levels are around 40g vs the normal 90g.

My macros are on point, but yet this past week I gained a pound.

Trying to make sense of it and does protein levels have a direct relation to weight loss.

170 kg (375 lbs) → 118.5 kg (261 lbs) — 51.5 kg / 114 lbs down in 7 months after Sleeve Gastrectomy

Seven months ago, on 10 March 2026, I underwent sleeve gastrectomy weighing 170 kg (375 lbs) at 191 cm / 6'3".

Today I'm 118.5 kg (261 lbs).

That's 51.5 kg (114 lbs) lost — 30.3% of my starting body weight. My BMI has moved from 46.6 to 32.5, from Class III to Class I obesity.

The scale is only part of the transformation. Since July, my combined recorded body measurements have reduced by 34.6 cm (13.6 inches). Since August alone, my waist has gone from 117 cm (46.1") to 110 cm (43.3"), along with noticeable reductions in my chest, hips, thighs and neck.

Recently the scale has slowed around 118–120 kg (260–265 lbs), but the measurements continue to change. That's been a good reminder that progress isn't always reflected by weight alone.

🎯 Next milestone: 109.5 kg (241 lbs), which takes me below BMI 30.

Still a work in progress, but seeing all the numbers together really puts the last seven months into perspective.

For others who had sleeve surgery: did you also notice your inches continuing to drop when your scale weight started slowing down?
