One of the questions we are asked most frequently by people preparing for surgery is how long they will need to stay in hospital. The honest answer is that it varies, but for most straightforward gastric sleeve procedures, you can expect to stay one to two nights before discharge.
What the Typical Stay Looks Like
For an uncomplicated laparoscopic gastric sleeve, most bariatric units aim for discharge on day one or day two post-operatively. The surgery itself is typically performed on the day of admission or the following day depending on the unit’s protocol, so a total stay of two to three days from arrival to departure is common.
At Weight Loss Riga, we had our surgery on the first full day after arriving. James was discharged two days after his operation. Kirsten stayed an extra day due to some additional monitoring needed around her Crohn’s disease. Both were discharged having met the clinical criteria the team required, not simply because a fixed number of days had passed. You should not feel pressured to leave before you are ready, and equally, there is no advantage to staying longer than necessary once you are genuinely well enough to go.
What Needs to Be in Place Before You Are Discharged
Your surgical team will assess several things before agreeing to discharge you. You will need to be tolerating sips of clear fluid without significant difficulty. Your pain should be manageable on oral medication rather than intravenous painkillers. Your vital signs need to be stable and within acceptable ranges. Your wound sites will be inspected to ensure there are no signs of infection or unexpected bleeding. Drains placed during surgery will typically be removed before discharge once output has reduced to an acceptable level.
Before you leave, you will receive discharge paperwork covering your post-operative dietary progression, supplement instructions, wound care, medications to take home, and clear guidance on when to seek medical attention. Do not leave without this information, and do not leave without understanding it.
What to Have Ready at Home
Preparing your home before surgery makes the first week back considerably easier. You will not feel like cooking, shopping, or making decisions about what to eat. Have your liquid and soft food supplies already in place before you go to hospital. Protein shakes, clear broths, smooth soups, sugar-free squash, and any prescribed supplements should all be ready and accessible without effort.
If you live alone, arrange for someone to be with you for at least the first few days. You should not be driving, should not be lifting anything heavier than a kettle, and should not be expected to manage household tasks. The temptation, particularly for people who are used to being capable and independent, is to push through. Resist it.
Travel After Discharge
If you have surgery abroad, as we did, there is an additional consideration: the journey home. Flying shortly after abdominal surgery carries an elevated DVT risk, and your surgical team will advise you on the minimum safe interval. For most bariatric units, this is typically a minimum of 24 to 48 hours after surgery before flying. Wear compression stockings for the entire journey and break up long flights or car journeys as much as possible.
The journey home after our surgery from Riga was manageable but not comfortable. Knowing that discomfort was coming and having prepared for it, with extra cushions, an aisle seat, and loose clothing, made it more bearable.
When to Seek Help After Discharge
Going home does not mean the monitoring stops. The most important warning signs are a persistent raised heart rate, fever above 38 degrees Celsius, increasing rather than decreasing pain, difficulty keeping any fluid down, wound redness or discharge that is spreading, or any feeling that something is simply not right. If you are in the UK and had surgery abroad, your GP is your first point of contact for non-emergency concerns. For anything urgent, go to your nearest A&E and tell them you have recently had bariatric surgery.

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.
