I did suffer a mild attack after surgery. I have changed my diet and don't eat shrimp often anymore. That seems to have helped. If anything I would think the surgery would help. Best to ask your Dr what he/she thinks. Good luck!
Everyone handles maintenance differently. We each have our own weight gain risk factors. Its important to know yourself. Will you need to remind yourself you had surgery? Is it healthy habits? Precautions? Simply eating less? Do whatever works for you to maintain and not go back to obesity.
Five years out, I never want to feel like my normal “obese” self before surgery. I feel better than normal after weight loss and maintaining in the 130's. I have no issues. I bounced back with minimal pain and I have no complications (Gerd, dumping or vomiting etc.)
Personally, I don’t need to remind myself. I have a healthy lifestyle. Maintaining has become habit/mundane. I don’t put much thought into it. I eat mainly healthy and indulge within reason. I give myself a ten-pound bounce range. If I gain, I go back to weight loss mode and work it off.
