Are you managing conditions like type 2 diabetes, high blood pressure, or sleep apnea?

Many people don’t realize that these conditions are often connected to an underlying chronic disease: obesity.

Treating obesity can play an important role in improving overall health. Research has shown that metabolic and bariatric surgery can lead to significant improvement or remission of obesity-related conditions for many patients, including:

âś” Type 2 diabetes
âś” Obstructive sleep apnea
âś” High blood pressure

For many individuals, weight loss through bariatric surgery has been associated with:
• Up to 83% remission of type 2 diabetes
• Up to 80% improvement or resolution of sleep apnea
• Up to 75% improvement in high blood pressure

Every patient’s journey is different, but addressing obesity can be a powerful step toward better health.

If you’ve been struggling to manage these conditions, learning about your treatment options could make a meaningful difference.

“Stronger, healthier, and proud of myself.”

That’s how Pam describes life one year after her gastric sleeve surgery with Team Cheregi.

Pam has reached her goal weight after losing 112 lbs, but the real transformation goes far beyond the number on the scale. She’s built healthier habits, gained confidence, and committed to taking control of her health.

Like many chronic conditions, obesity requires ongoing care and long-term lifestyle changes. Pam understands that this journey continues — and she’s embracing it every step of the way.

We couldn’t be more proud of the dedication and perseverance she’s shown over the past year. 👏

If you’ve been thinking about taking the first step toward improving your health, learning about your options could make all the difference.

Weight Loss Wednesday đź’ˇ

One of the most powerful habits for long-term weight loss success is tracking your progress.

Learning to monitor your calories, protein intake, and activity can make a significant difference in your journey. In fact, studies show that patients who consistently track their habits can achieve up to 48% better weight loss outcomes compared to those who don’t.

But with so many apps available, it can be hard to know which one to use.

That’s why Advanced Bariatrics partners with baritastic.
When you connect using our program code: 509564, you can:
âś” Access our bariatric binder and nutrition guidelines anytime
âś” Track meals, hydration, protein, and activity
âś” Order recommended vitamins and high-protein meal replacements
âś” Keep your weight loss journey organized in one place

Small habits + consistent tracking = long-term success.

Today she’s:
🚴‍♀️ Enjoying biking adventures with her husband
👩‍👧‍👦 Keeping up with her kids
đź’Ş Experiencing relief from joint pain
❤️ Living more present and engaged in everyday life

Stories like Stephanie’s remind us that treating obesity can open the door to more freedom, movement, and meaningful moments with loved ones.

Celebrating strength, courage, and self-care this International Women’s Day 💜

In honor of International Women's Day, we’re celebrating these incredible women — and the hundreds of women who have chosen to stand up for themselves and reclaim their health.

They’re redefining expectations.
They embrace true body positivity.
They say no to mom guilt.
They choose to invest in their health and their future.

Because bariatric surgery isn’t about appearance — it’s about getting healthy.

When women improve their physical health, it allows them to show up stronger physically, emotionally, and mentally for the people who matter most.

And sometimes the most powerful thing a woman can do is put herself first.

Today we celebrate every woman who has chosen courage, health, and self-love. đź’ś

Non-Scale Victories like this are everything. 🎉
Obesity can take away the simple freedoms many of us want most — the ability to move freely, stay active, and fully enjoy time with the people we love.

That’s why we love celebrating moments like this.
Rachel and her husband have lost a combined 265 lbs, and the impact goes far beyond the number on the scale. Now they can run, play, and make unforgettable memories with their beautiful daughter — including family adventures at Disney. ✨

Their journey is a powerful reminder that improving your health doesn’t just change your life — it can change your family’s future too.
Whether someone explores medical weight loss or bariatric surgery, investing in your health can open the door to more moments that truly matter.

We couldn’t be more proud of this incredible family. 💙

Your weight loss journey should never be “one size fits all.”

Every patient’s body, health history, and goals are different — which means the right treatment plan should be personalized, too.

Some patients see great results with weight loss medications.
Others may benefit more from bariatric surgery.
And even within surgery, the most popular option may not always be the best option for you.

That’s why education and individualized care matter.

At Advanced Bariatrics our team focuses on helping you understand all of your options so you can make the most informed decision for your health and long-term success.

All we ask is that you come with an open mind and a willingness to learn.
Our goal is simple: help you achieve the health and weight loss goals you’ve been working toward.

Your journey. Your body. Your best path forward.

Talk about inspiring! 🏆

Dana is down 160+ pounds and counting after her SADI-S procedure — and her transformation is more than physical.

Yes, the results speak for themselves.
But what truly sets her apart is the mental and emotional growth she’s embraced along the way.

She may call it a “silver medal,” but we see gold — and she’s building something even greater: lifelong confidence, resilience, and strength.

Sustainable weight loss isn’t just about the scale.
It’s about the mindset shifts.
The self-belief.
The daily decisions that add up over time.

We are so proud of the dedication she’s shown and can’t wait to see her continue thriving for years to come.

Here’s to long-term success and a future filled with pride. 💛
