⭐️The Best of Dr. Yadegar - From the Archives🎥

Dr. Yadegar shares what he’s learned from decades of experience caring for bariatric surgery patients:

“I feel very close to my patients. And I’ve had enough experience to know — when you make the right moves, you will succeed.”💙

So what are those “right moves”?

It’s often not about starting from scratch, but about returning to the basics that brought you success in the first place.

Dietitians remind us all the time:

-Go back and review what you learned in your pre-op classes
-Check your food labels
-Track your protein
-Don’t underestimate your portions (or your protein intake)

It’s not about shame, it’s about recalibrating.

Life gets busy. You start to feel good. And it’s easy to forget the small habits that matter most.

Dr. Yadegar offers more than surgery, he offers real support. Real care. A belief in his patients that never fades, no matter how long it’s been. If you’re an existing patient who needs a gentle reset, this one’s for you. 💙 And call us if you need help.

If you’re looking for a bariatric surgeon who truly listens, welcome. You’re in the right place.💙

💙Dr. Yadegar’s patients consistently praise his deeply compassionate bedside manner and dedication to long-term outcomes. After surgery, he even gives patients his personal cell phone number, ensuring they feel supported every step of the way.

💙"Hi, I’m Kym, and I can finally say I am living a happy, healthy, and energetic life. Today, at 37, I weigh between 178 and 183 pounds, and I feel fantastic. When I had weight loss surgery with Dr. John Yadegar in 2022, my life completely transformed, and I want to share my story to inspire others who are on their own journeys.

I've struggled with my weight for as long as I can remember. In elementary school, I was already over 200 pounds. My battle with weight led to an eating disorder, bulimia, which I struggled with on and off until my mid-twenties. By then, my weight had climbed over 300 pounds, and I knew I needed to make a change. I started eating healthier and walking 2-3 miles five days a week. Over four years, I lost 100 pounds and managed to keep it off.

Life, however, brought more challenges. Pregnancy led to weight gain and postpartum depression. Losing my mom in January 2019 further impacted my mental health. Despite these difficulties, I remained determined. I initially planned bariatric surgery in October 2019, but two weeks before the surgery, I found out I was pregnant again.

After having my second child in June 2020, my weight reached 394 pounds. Postpartum depression struck once more, and I gained back the weight I had lost. When my mental health stabilized, I started losing weight again slowly. Determined to proceed with weight loss surgery, I consulted with Dr. John Yadegar. I completed all the requirements and ensured I wouldn't face any more interruptions by getting an IUD.

💙In February 2022, I had gastric bypass surgery with Dr. Yadegar. Since then, I have lost over 80% of my excess weight. I am proud of my success and thrilled with my current weight. I am also working on getting skin removal surgery, which should help me lose another 30-50 pounds.

Having weight loss surgery was the best decision I've ever made. It has allowed me to enjoy life with my kids to the fullest. I can run around with them, swing on playground swings, and slide down slides - things I couldn't do when I was heavier. My mental health has also improved significantly. I now understand how much my weight affected my depression. Though my depression still comes and goes, it’s more situational now, and I have learned to manage it much better.

I am especially grateful to Dr. Yadegar, who made this experience a breeze. He made me feel 100% confident in the procedure and I highly recommend him to anyone interested in getting weight loss surgery. He’s the best!

I keep a picture of myself from October 2020 on my phone as a reminder of how far I’ve come. Weight loss surgery has been an incredible tool that has helped me keep the weight off and enjoy my life. I am so grateful for this journey and hope my story can inspire others to believe in the possibility of a happier, healthier future."

Thank you, Kym, for sharing your inspiring story!💙

💥We understand the Bariatric surgery journey asks a lot of you.💥You’re trying to stay on top of your vitamins, track your protein and water, get in some exercise, schedule follow-ups…. AND THAT’S ON TOP OF everything life already demands (work, family, the unexpected)… it’s a lot.💥This is a lot of adulting.

One of the bravest, healthiest things you can do is say, “I need some help getting back on track.”💙

The routines that stick are usually the ones that fit your real life—ones that support your health without burning you out.💙
When you build habits around what actually helps you feel better, stay on track, and take care of yourself—that’s how real progress lasts.
Think sustainable, not perfect.💙
