While any good bariatric surgeon can make the short term risks and complications associated with a gastric bypass surgery clear, it can be harder to really get the gastric bypass long term issues across. Unfortunately, there are quite a bit of long term concerns that a bypass patient needs to understand before proceeding. A gastric bypass will permanently change the way you have to eat, forcing you to eat small frequent meals, chew all food thoroughly, and stop drinking while you eat. You'll need to take nutritional supplements for the rest of your life, and there will always be the risk of malabsorbtion issues.
