Risks after weight loss surgery
In the days just after weight loss surgery, you cannot eat normally and it is important to take only tiny amounts of fluid at once, with no solid food at all, so that the wounds have a chance to heal. On the second week you will be able to start eating thin pureed food but it may be several weeks before you can eat solid food. Eating too much too quickly can put pressure on the sutures and staples, or on the gastric band, causing rupture, causing leakage through the wound or slippage of the band.
After several weeks, your diet needs to be adapted to your much smaller stomach capacity, while still providing the nutrients that you need to stay healthy. It is possible to push your stomach to the limit, even with a band firmly in place, or after a stapling operation. This can cause you to lose weight more slowly than expected. Overeating with a gastric band in place can also cause the band to damage the outside of the stomach, causing erosions and soreness, which can be very painful.
At the other end of the spectrum, people whose food intake does reduce dramatically can find that they become thinner very rapidly after weight loss surgery. Loose skin can then become a problem and further cosmetic surgery may be required to remove folds of excess skin left behind.
Impact of weight loss surgery on lifestyle
The important thing to consider before you have any type of weight loss surgery is that the procedure is disturbing the natural digestive process and is highly abnormal. Although the actual obesity surgery may go well, with no surgical problems, the overall safety of weight loss surgery depends on how well you manage to adapt your lifestyle afterwards. Having weight loss surgery can prevent illness due to obesity without needing to think about dieting but you will need will power to control your intake of food to prevent malnutrition and long-term damage to your digestive system.
