Patients typically stay in hospital for one to three days after surgery. The use of minimally invasive (keyhole) surgical techniques for bariatric surgery causes less pain and surgical stress to the patient, and allows for faster recovery. Most patients are able to return to work in about two to four weeks, especially if their work does not involve heavy physical activity.
Immediately after surgery, patients will be placed on a special diet plan detailed by the bariatric surgery team. There is a gradual progression from a liquid-only diet, to soft foods and then finally back to solids. This adjustment period typically takes about six to eight weeks. During this time, patient should take sips of fluid regularly throughout the day to stay hydrated.
In the first six to eight weeks after surgery, patients should also start doing some light exercises like brisk walking, as recommended by the doctor. Exercises that are more intensive like running, cycling, resistance training and weight training should be deferred until the wounds heal completely and the patient is comfortable with eating and drinking regularly with the changes brought about by the surgery.
The most obvious change in the long term after surgery is that patients will be able to feel full much faster from eating a drastically reduced amount of food. This usually amounts to about four to five tablespoons of solid food every meal. Patients should maintain a balanced diet and prioritise taking proteins over other food types to maintain muscle mass during the period of weight loss. To maintain healthy bodily functions, all patients will have to take vitamin supplements regularly after surgery as well.
The change in the shape of the stomach will compel patients to chew every mouthful of food completely, and slow down between every mouthful of food. On top of this, the patient should avoid drinking about 30 minutes before and after meals, as the stomach may not have the capacity to accommodate both solid food and fluids together.
With successful weight loss and better health, patients typically feel more energetic, have less joint pain and are more confident in themselves. There is usually greater enthusiasm for doing things they have not done or were not able to do previously.
