This hub covers what comes after bariatric surgery: the vitamin and nutrient routine your body now needs, how digestion and eating patterns change, and what recovery actually looks like week by week, across gastric sleeve, gastric bypass, and duodenal switch.
Bariatric surgery changes a lot more than the number on the scale, and the research and lived experience behind it fills a lot more ground than most people expect going in. This hub is built for two groups of readers at once: people who are still deciding whether surgery is the right path, and people who've already had a procedure and are figuring out what recovery and daily life look like now.
If you are in the deciding phase, the questions tend to be big picture. What is the actual difference between gastric sleeve, gastric bypass, and duodenal switch? What does the research say about outcomes, risks, and who tends to be a good candidate? What does the process of qualifying for surgery involve, from insurance to the pre-surgery requirements many programs use? We cover these from the ground up, without assuming you already know the terminology.
If you have already had surgery, the questions shift toward the practical and the daily. What vitamins and nutrients does your body need differently now, and why? How does eating change, in terms of portions, pacing, and the foods that tend to cause problems? What does recovery actually look like week by week, and how does that timeline differ across the different procedures? This is where most of the articles in this hub live, because it is where most of the day-to-day questions are.
This is our most developed hub, and it is organized to be walked through in order or dipped into as specific questions come up. Some pieces are foundational, covering the differences between procedures or what the qualification process involves. Others are focused on the mechanics of recovery, like nutrient timing or how digestion adapts. All of them cite the clinical research or institutional guidance behind the specifics.
Bariatric surgery is a significant medical decision with real risks and real benefits, and the specifics vary a lot by individual, procedure, and surgeon. Nothing in this hub replaces the guidance of your own surgical and nutrition team. Use it to walk into those conversations with better questions, and to make sense of what you are told once you are in recovery.
