Most patients do not experience any long-term issues after a bariatric procedure. However, there is always some risk involved when it comes to weight loss surgery. Experiencing a complication is the most serious sign that you may need revision surgery. After LAP-BAND surgery, for instance, a situation may occur where your lap band becomes loose or slips out of place. These complications require immediate attention and can affect your digestive system and your ability to lose weight. Though pain and sickness can be a sign of your body adjusting post-surgery, if these issues persist, it is important to speak with your physician and consider revision surgery.
