Inspiration
In 2013, while working at Doctor Soliman Fakeeh Hospital in Saudi Arabia, I discovered the transformative power of Bariatric and Metabolic Surgery. Witnessing its profound impact on patients’ lives motivated me to dedicate my career entirely to this field. I saw the urgent need for such treatments in Pakistan, which led me to bring this life-changing practice back to Karachi to make it accessible to those in need.
Education
My medical journey began at Sindh Medical College, where I earned my MBBS. I pursued surgical training under The Royal College of Surgeons in Dublin, Ireland, and became a Fellow of The Royal College of Surgeons of Edinburgh in 1999. To expand my expertise, I trained in advanced laparoscopic and bariatric procedures in Egypt, Germany, and Sweden, and earned a diploma in Laparoscopic Surgery from Louis Pasteur University, Strasbourg, France.
Career
Throughout my career, I have had the privilege of holding leadership roles, including Chief of Surgery at Patel Hospital in Karachi, where I implemented international standards of care, and Consultant Surgeon at Indus Hospital, where I established advanced laparoscopic and cancer surgery programs. At Doctor Soliman Fakeeh Hospital, I performed over 1,000 laparoscopic surgeries. Since 2018, I have continued my work at South City Hospital and Doctor Obesity Clinic, helping patients reclaim their lives through innovative and personalized surgical care.
Weight Loss Journey
For over 20 years, I struggled with my weight. I exercised, followed diet plans, and played squash regularly. While I did lose weight, it always came back—with a little extra each time. Eventually, I reached 100 kilograms, became pre-diabetic, developed high blood pressure, and experienced back strain. That’s when I realized it was time to follow the same advice I give my patients. I underwent Sleeve Gastrectomy, and Alhamdulillah, the results transformed my life. Today, I am healthier, happier, and more confident in helping others embark on their weight loss journeys.

I’ve struggled with obesity for the past 30 years and tried every diet under the sun, to no avail. I developed multiple obesity-related health issues, including PCOS, hypothyroidism, hypertension and joint issues. When my weight touched 100 kgs and I was diagnosed with pre-diabetes, I finally decided to take charge of my life and find a durable & long-term solution – which led me to bariatric surgery. Now 16 months post-surgery, I am down 27 kgs and disease free! I truly understand what you’re going through—the challenges, the triumphs, and everything in between, and my experience lets me connect with you on a deeper level and offer support that’s both compassionate and practical.
In my role as your Follow-Up Bariatric Coordinator, I am here to guide and support you through your post-surgery journey. Whether it’s helping you adjust to dietary changes, or navigating long-term lifestyle modifications, I’m here to ensure you achieve the best possible outcomes.
