Let’s play round 3 of True or False with Dr. Feiz 👨‍⚕️

💤 Weight loss surgery can improve sleep apnea.
✅ True — By reducing excess weight around the neck, surgery can actually cure sleep apnea caused by obesity.

🍽️ Surgery affects your hunger hormones.
✅ True — When we remove part of the stomach, we also remove the cells that produce hunger hormones. That means you’ll feel fuller naturally, similar to what weight loss injections do, but without the synthetic chemicals.

Weight loss surgery isn’t just about the scale, it’s about transforming your health from the inside out.

Losing 190 pounds in just 9 months, this patient’s story is nothing short of extraordinary. When he first came to see me, he was struggling with diabetes and felt limited in his daily life. After discussing the gastric sleeve procedure, he decided to take that courageous step toward a healthier future.

Today, he’s not only 190 pounds lighter, he’s stronger, more energetic, and back in the gym doing things he never imagined possible. Most importantly, he now has the energy to enjoy time with his grandchildren and truly live life to the fullest.

These are the moments that make this journey so rewarding. I’m incredibly proud of this patient’s dedication and transformation and it’s proof that with the right mindset and the right tools lasting change is possible!

Proudly taking a selfie, this patient radiates confidence, health, and happiness after her weight loss journey with Dr. Feiz.

Think you know bariatric surgery? Let’s play True or False!
After surgery, you can still enjoy your favorite foods, just in smaller portions. And gastric sleeve isn’t “less than” gastric bypass. Both have similar weight loss results and success rates, making the sleeve a fantastic standalone option for many patients. Knowledge is power when it comes to your weight loss journey.

Heartburn might feel like a minor nuisance, but if left untreated, it can lead to bigger issues, even increasing the risk for cancer much later on. Medications, diet changes, and avoiding trigger foods often help, but when those aren’t enough, surgery can be the most effective long-term solution.

Do you think Dr. Rim can explain heartburn in 30 seconds?

There are a lot of myths about weight loss surgery. Your stomach doesn’t “stretch back out.” Weight regain usually comes from eating habits, not the surgery itself. And you don’t have to weigh 300 pounds to qualify. Eligibility is based on your overall health and body mass index. Understanding the facts is the first step toward lasting results.

Behind every before and after is a story of courage, perseverance, and self-love. 💪We’re so proud of our patient for tak...

Let’s grade some popular weight loss methods 👇

🍋 Lemon water — Myth busted. There’s nothing magical about lemon water for weight loss. It’s refreshing, sure, but it won’t burn fat. Grade: 1/10

🍵 Detox teas — Not a weight loss solution. Most just act as diuretics or laxatives, making you think you’ve lost weight. Grade: 0/10

🍗 High-protein diet — Now this one works. Protein keeps you full longer and fuels your body cleanly, especially when it’s lean protein. Grade: 8/10

Weight loss is about science, not shortcuts. Choose smart, sustainable habits over gimmicks. 💪

There are certain situations where robotic surgery can offer key advantages over traditional laparoscopic techniques. 🤖✨

Here’s why:
1️⃣ 3D visualization — providing exceptional depth and precision, especially in revision cases.
2️⃣ Superior dexterity — robotic instruments can work effectively in tighter areas like the pelvis or anterior abdominal wall.
3️⃣ Improved retraction and assistance — allowing for smoother, more controlled movements during surgery.

Robotic surgery isn’t always necessary, but when it is, it can make all the difference in achieving a precise and safe result. 👨‍⚕️
