Long-term risks associated with bariatric surgery

What are the long-term risks associated with having bariatric surgery? Bariatric surgery is one of the safest types of surgery in the field of surgery. The actual risks of bariatric surgery we could actually say and has been proven to be less than the risks of other operations like knee replacements or even keyhole surgery to to remove one's gallbladder. So bariatric surgery these days, when done in expert units, is extremely safe. In terms of long-term risks of bariatric surgery, actually very few, I would say. Ultimately, it's down to the patient's compliance. So if the patients listen to the advice given to them by their clinical team, then there are really no long-term consequences. One potential long-term consequence could be that if the patient does not follow the advice of taking regular multivitamin tablets that may develop deficiency in vitamins in the future, but that's again, if they don't take the necessary vitamin supplements. Another potential is if they don't eat properly or listen to the signals of reduced hunger and early fullness, then in the long run, it is of course possible that they may suffer from some weight gain.
