The first twenty-four hours after gastric sleeve surgery are not as dramatic as you might be imagining, but they are important. Your body has just been through a significant procedure and it needs time to begin healing. Here is an honest account of what those first hours typically look like.
Immediately After Surgery
When you wake up in the recovery room, your main job is simply to come round slowly. There will be monitoring equipment attached to you, checking your blood pressure, heart rate, and oxygen levels. A nurse will be close by. You may feel groggy, cold, or emotional. All of that is normal.
Pain at this stage is usually managed because you are still carrying medication from the procedure. The team will assess your comfort and adjust your pain relief as needed. If you are in discomfort, say so. There is no benefit to being stoic at this point.
Once you are stable and alert, you will be moved to your room or ward. For James, surgery was in the morning and he was in his room by early afternoon.
The First Sips of Water
One of the first milestones of your recovery is taking small sips of water. Your surgical team will tell you when this is safe to start, usually within a few hours of your procedure. The emphasis is on small. A teaspoon at a time, not a glass. The new stomach is swollen and freshly stapled and needs to be treated gently.
If drinking causes pain or significant discomfort, let your nurse know. Some discomfort and pressure is expected, but sharp pain should be flagged.
Getting Up and Moving
This feels counterintuitive when you are exhausted and sore, but getting up and moving is actively encouraged in the first twenty-four hours. Even a short walk to the bathroom and back is helpful. Movement reduces the risk of deep vein thrombosis and blood clots, helps your digestive system start to wake up, and can actually help with pain by preventing stiffness.
You will likely be given compression stockings and possibly blood-thinning injections as standard precautions against clots. These continue for a period after you go home.
Managing Discomfort
The most common sources of discomfort in the first twenty-four hours are the surgical wounds themselves, the gas used to inflate the abdomen during laparoscopic surgery, and general soreness from the procedure. The gas discomfort in particular can be uncomfortable and sometimes refers to the shoulder tip, which feels strange but is normal.
Pain relief will be offered to you. Take it when you need it. Keeping pain under control in the early hours makes moving easier, which in turn helps recovery.
What You Will Not Be Doing
You will not be eating. You will not be drinking large volumes of anything. You will not be doing any activity beyond gentle movement. This is a day for rest, monitoring, and very gentle recovery. Expect to feel tired, a little sore, possibly emotional, and not very hungry. The lack of hunger surprises many people but it is completely normal in the immediate post-operative period.
Overnight
Most patients spend at least one night in hospital after their gastric sleeve. Nursing staff will check on you through the night, monitoring your vital signs and making sure you are comfortable. Sleep may be patchy because of the monitoring and discomfort, but even resting is beneficial.
By the morning after surgery, most people feel meaningfully better than they did the evening before. The first twenty-four hours are often the hardest part of the physical recovery. Once you are through them, things tend to improve steadily from there.

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.
