- Recovery: on average 3 to 6 weeks (WeightWorks).
- A daily thrombosis injection at about the same time.

How does recovery after weight loss surgery go?
The first days are about pain and nausea, the most common complaints after the operation. You start with sips of water and build up to liquid food in hospital. At home you continue: liquid, then puréed, and over the following weeks gradually more solid.
WeightWorks mentions an average recovery time of three to six weeks after a bypass and says there is no essential difference in recovery between the types of operation. Your body has to adjust to a major change in the digestive system, whatever the technique.
The first weeks at home
You give yourself a thrombosis injection once a day at about the same time; a nurse teaches you how on the ward. Constipation is common because you move, drink and eat fibre less. According to Vitalys you can first try a microlax enema from the pharmacy and otherwise call the medical helpline. You can lie on your stomach or side as soon as it feels comfortable.
Work, driving and sport: when is what allowed?
With an office job you can usually work a few hours a day after about two weeks and build up from there. With physically heavy work, it is wise to start building up after four to six weeks. Household tasks are built up gradually too, within the 2.5 kilogram lifting limit.
Do not drive in the first 24 hours after anaesthesia. After that it depends on your recovery and medication: if you use tramadol, do not drive for the first two weeks. Check your car insurance conditions as well. Swimming, baths and saunas wait until after two weeks.

Warning signs that do not belong to normal recovery
Contact your centre immediately with increasing abdominal pain, fever, a fast heartbeat, shortness of breath, persistent vomiting or if you cannot keep anything down. After a bypass, sudden cramping pain after eating can point to an internal hernia, also later in recovery.
If in doubt, call rather too early than too late. Centres have a medical helpline for exactly this, and the nurses know which complaints are part of recovery and which are not.
Eating during recovery
Food is built up in phases: clear fluids, then liquid, then puréed and finally solid food. Ziekenhuis Rivierenland starts the day after surgery with small portions such as a 30 millilitre cup of yoghurt or apple sauce.
