What to expect after bariatric surgery

There are no doubt some questions once you’ve had bariatric surgery and your weight has started to decrease. There is no ‘normal’ or standard set of outcomes for everyone, however we can give you a rough idea about what to expect and help you set some realistic health goals.

How much weight should I lose?

Your weight loss will depend on the type of surgery you’ve had, as there are lots of different options. A sleeve gastrectomy of gastric bypass will typically lose faster than a LapBand®, as will a primary gastric bypass compared to a conversion.

The important thing to note is that everybody’s weight loss journey is unique, and there is no right or wrong.

Will my weight loss be linear?

Your weight loss will change over time, you may find if you weight yourself daily it can fluctuate up and down significantly. This can be stressful, and is not necessary to weigh yourself every day. Small fluctuations balance out over time, and if you only weigh yourself every week or two the likelihood is that you will see the numbers going down.

Receiving lots of positive comments

You may hear lots of positive comments following your surgery about how great you look. But it may not feel right, or you may not ‘see’ the weight you’ve lost. Sometimes it’s difficult when you’re seeing yourself day-to-day to see this bigger changes. Your brain is also used to you as a certain way and can take a while to catch up.

The number on the scales isn’t moving but my clothes are tighter!

No, your mind isn’t playing tricks on you! It occurs often after bariatric surgery due to changes in body composition. Sometimes you may have gained muscle and lost fat, which changes your shape but doesn’t change your overall weight.


Remember, there’s no ‘normal’ weight loss after bariatric surgery. What’s most important to keep at it, and talk to any of your support team if you have questions.
