As a bariatric dietitian with nearly nine years of experience, I’ve seen many patients succeed after surgery — but I've also seen the common misconceptions and challenges they face. Bariatric surgery is a transformative tool, but it’s only part of the journey. Here are ten things I wish all patients understood before they start this life-changing process.
Preparing for bariatric surgery
1) It’s more than just surgery
This isn't a quick fix. Surgery is the beginning of a lifelong commitment to new eating habits, physical activity, and mindful living. Be ready to make lasting changes.
2) Emotional & mental prep is crucial
I’ve seen too many patients struggle emotionally after surgery. It's not just about physical preparation — mentally preparing for the changes to your body and your relationship with food is just as important. Seek support early.
3) Your stomach will be smaller, but cravings won’t disappear overnight
Your hunger cues will change, but emotional eating and cravings can still be a challenge. This is a stomach surgery, not a brain surgery. Start developing healthier coping mechanisms now to avoid struggles later.
4) Meal portions will shrink — dramatically
Post-surgery, portions will be much smaller than you're used to. Eating too quickly or in large amounts can cause discomfort. Practicing slow, mindful eating before surgery can help ease the transition. Use smaller plates and utensils to mentally adjust to the smaller portion sizes you'll need post-surgery.
5) Support systems make all the difference
Having a network — whether family, friends, or support groups — helps patients stay on track. I've watched many patients succeed when they lean on others for encouragement and accountability.
Life after bariatric surgery
6) Weight loss isn't linear
Some patients lose quickly at first, then stall. I've seen this happen with many patients, and it's normal. Staying patient, following the plan, and keeping in touch with your bariatric team is key to long-term success.
7) Nutrient deficiencies are real
I've encountered countless patients with low levels of B12, iron, and vitamin D. This is one of the most crucial things to manage post-surgery because it can impact your health for decades to come. Regular lab work and lifelong supplementation are not optional — they're essential for your health.
8) Exercise will make or break your results
Surgery alone won’t get you to your goal. I’ve seen the best results in patients who prioritize consistent physical activity. It doesn’t have to be intense — just something sustainable that gets you moving.
9) Life will look different, and that's okay
Your social and food-related experiences will change. You’ll learn how to navigate social events differently. Embrace the new you, and give yourself grace along the way.
10) Success takes work, every day
The honeymoon phase doesn’t last forever. Bariatric surgery is a lifelong tool, but maintaining success requires daily effort — something I remind every patient who walks through our program door.
