This is to provide a more monitored environment for those with severe sleep apnoea, cardiac conditions or other existing health concerns. Your family can visit you here although restrictions apply.Pain Management: You will have a PCA (Patient Controlled Analgesia) to provide post operative pain relief. Your nurse will regularly monitor your pain level. Be sure to notify your nurse if your pain remains uncontrolled or you have nausea.Mobilisation: You will be asked to sit up and dangle your legs over the edge of the bed four (4) hours after the operation. Your nurse will assist you but you will be required to move by yourself. Walking and sitting out of bed are vital activities to assist your recovery and will decrease your chances of post-op complications. You will be encouraged to do deep breathing and leg exercises whilst in bed.Nutrition: Day of operation: You may have ice to suck to keep your mouth moist.Day One: You can start having sips of water to drink.Day Two: Your diet will increase to full fluids today. This diet includes clear soup, jelly, custard, milk and cordial. Remember to take VERY SMALL SIPS and start with a teaspoon.

When you sense fullness, STOP.At Home: It is important to maintain an active life. You will do better and reduce your risk of complications if you are working towards getting back to normal quickly.

Aim for at least 1 litre of water per day. LIFE AFTER A SLEEVE GASTRECTOMYAfter your operation you may experience some of the following:Dizziness: Occasionally you may feel light headed. This is due to the fact that you are not drinking as much liquid as you were able to before surgery; therefore the volume in your body is reduced. When this occurs do not panic. If you can find a comfortable place to sit or lie down, do so. Your body will adjust and the blood will be redistributed adequately after a short interval. Aim to drink 1.5 litres of fluid per day.Altered Bowel Habits: Bowel habits may be altered after the surgery. In the beginning, you may have watery bowel movements. Do not expect your bowel movements to be regular until you start eating solid food. For most, bowel habits should become regular and you should have one bowel movement every day and usually less in quantity than you are used to.Vomiting: During the two months after surgery, you will probably experience a few episodes of vomiting. It is important to remember your new stomach is approximately 200ml and can be easily overwhelmed. You must eat slowly and stop when you feel full. Meals will take up to 45 minutes. Vomiting can occur due to too fast eating, poor chewing and inappropriate food.Too much vomiting or retching will cause secondary swelling and possible obstruction of the passageway. Nausea: Nausea is a side effect of any gastric operation. This problem may start on the third day after the operation or a couple of weeks after discharge from hospital. This is a side effect of the operation that is responsible for some of the massive rapid weight loss.Even though you may experience severe nausea you should make an effort to eat at least three to four small meals a day and drink at least three to four cups of water a day. Anorexia: Anorexia, complete lack of appetite or forgetting to eat, is a problem some patients experience. This is dangerous. Make an effort to eat at least three to four meals a day.Hypoglycaemia: Light headedness, passing out and running heart beat are typical of hypoglycaemia. This is due to your not eating at regular intervals as recommended. Do not go for more than six hours without eating.GENERAL DIET GUIDELINESInitially patients are on a pureed diet for 3 weeks, but as the operation settle, the diet can progress to normal consistency of healthy choices.
