“I hit 101lbs down a couple of weeks ago, and I’ve been stuck at 203/204 for about 2 weeks. I bought this tunic dress on clearance online as a goal dress to help me get to onederland. Y’all, this is a MEDIUM, and it fits! Not only that, but the leggings I have on are torrid 1, and they are too loose! I need the 0s now. My point of this post is my realization that the scale isn’t the ONLY judge of size or victories. I rely on it so heavily that I get depressed when it doesn’t move like I want it to. I know I am more than my dress size but DANG! Putting on a medium sure felt good.”

“Today is my 1st surgiversary. It wasn’t perfect, there were bumps and obstacles, but I would do it all again (I hope I don’t have to, lol). I’ve lost 128 lbs, but more importantly, I lost joint pain, shortness of breath at every little physical assertion, backaches, hatred of mirrors, and clothing shopping. I would encourage anyone considering weight loss surgery to do your research; they have pros and cons, and figure out if they are worth it to you. I HIGHLY recommend Mexico Bariatric Center in Tijuana; they treated us well and did a fantastic job from the beginning of the decision-making progress to the ride to the airport afterward!”

Weight Loss Expectations After Mini Gastric Bypass Surgery

The one anastomosis gastric bypass, or mini gastric bypass, incorporates restrictive and malabsorptive methods, similar to traditional RNY gastric bypass. It is a more straightforward procedure than the classic gastric bypass but has the same outcomes. MGB helps patients lose weight quickly and safely and reverses the comorbidities.

The dramatic transformation of individuals with MGB is remarkable. Patients lose 10 to 15 lbs weekly for the first few months and slow down afterward. Average expected weight loss timeline:

  • 3 months post-op: 35%-37% of excess weight loss*

  • 6 months post-op: 55%-60% of excess weight loss*

  • 12 months post-op: 73% of excess weight loss*

  • 18 months post-op: 78% of excess weight loss*

*Individual results may vary

Is Mini Gastric Bypass Surgery Right For Me?

If you have ulcer problems or are taking Aspirin/Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) regularly, gastric sleeve or duodenal switch are better options for you.
