Symptoms · After weight-loss surgery
Weight that stops coming off after a sleeve operation
The short answer
A pause in weight loss is normal after a sleeve gastrectomy. Most people lose weight fastest in the first months, then the loss slows and levels off as the body adapts. A plateau is not a failure. Check your portions, protein, drinks, activity, sleep and medicines first, and keep your follow-up visits. See your surgeon if you start to gain weight again, cannot eat normally, vomit often, or have severe reflux.

What can cause it
Normal adaptation
The body slows down after the first months, and loss levels off.
Next step: Review your habits; keep follow-up visits.
Drinks, snacks and grazing
Juices, sweet coffees and frequent small snacks add calories without filling you.
Next step: Keep a food diary for two weeks, and include drinks.
Too little protein or activity
Losing muscle lowers the energy you burn.
Next step: See a dietitian; add walking and strength exercise.
Medicines or a medical condition
Some medicines, an underactive thyroid, or other conditions slow weight loss.
Next step: Blood tests and a review of your medicines.
A stretched sleeve (later on)
A year or more after surgery, eating larger portions again with weight gain.
Next step: See your surgeon for tests.
What you can do now
- Keep a food diary for two weeks, including drinks
- Aim for protein at every meal, in small portions that you chew slowly
- Drink water between meals and not with meals
- Walk every day, and add strength exercise
- Take your vitamins, and keep your follow-up visits and blood tests
Tests your doctor may order
- A review of your weight and eating habits with a dietitian
- Blood tests: thyroid, vitamins, iron and blood sugar
- A stomach X-ray or camera test (endoscopy) if you regain weight, vomit or have reflux
When is surgery needed?
- Most people never need another operation.
- If weight regain is due to a stretched sleeve or severe reflux, your surgeon may discuss options, including a revision operation.
- Medicines for weight loss may suit some people. Your doctor decides.
Questions people ask
Is a plateau normal?
Yes. Weight loss is usually fastest in the first months and continues more slowly after that.
Should I eat even less?
No. Eating too little protein can cause muscle and vitamin loss. Focus on protein, small portions, and drinks without calories.
Can I drink fizzy drinks?
They are best avoided, because they add gas and often calories.
