review

    I consulted with many different bariatric Doctors and I wanted to make sure that I selected the right one and the best procedure for me. I chose Dr. Portocarrero because of his experience and his patience and understanding regarding my concerns and untroducing me to a new less invasive procedure (endoscopic sleve gastroplasty). He is an amazing caring person aswell as his staff. I felt so comfortable and my results are already impressive with just one week post op, (0ct 16 2021 to oct 20 2021) and 17 lbs down already and I feel great. I realized that I made the right choice immediately upon meeting Dr. Portocarrero. My surgery turned out great , his staff was awesome and he knows his stuff.. a genius! Thank you to him and his staff for making my experience very comfortable and amazing. I was nervous at first but because of the professionalism exemplified, I am so happy about my decision. I could not have made a better choice, dr. Portocarreo lives up to his outstanding reputation, he really made sure I was totally comfortable with the procedure and mapped out the perfect health plan to get me on the road to a healthy living. I would definitely recommend Dr. Portocarrero to anyone who is looking to start this journey towards their weight loss chapter of their lives! THANK YOU DR. PORTOCARRERO

    I was searching about this procedure for a few years already, but didn’t decided until now, why?... I didn’t like the idea of an incision, suture and remove part of my stomach and the worst feeling was knowing that I will not be able to eat some foods “like” forever, so Dr. Portocarrero start explaining to me how this procedure was, and neither is invasive because is done endoscopically and the sutures are inside, and there’s no cut neither remove any part of your stomach, just the size of it will be reduce and the follow through care and diet will help you lose weight, and the most important thing to me: to eat whatever I like in the long run even if it was going to be a cup size (better than nothing) I love to eat, and I don’t thing I do it so unhealthy, but being Peruvian is why is so hard NOT to eat, our food is one of the best, but we use a lot of carbs combine with protein, rice, potatoes, pasta, and for me, loving to cook didn’t help me that much either on my goals to reduce my weight.
    I didn’t care much about my weight before because I was very mobile, enjoy the gym, and my job is basically a 8 hours 5 days a week gym, have been a big girl since I remember, but, this was the major reason I did the ESG, I have osteoarthritis in my right knee, after time off and PT (Physical Therapy) helped maybe 50%, but the pain was growing and getting stronger, swollen and couldn’t bend my knee without an excruciating pain, and after almost 10 months of disability I decided that was enough, I’m only 45 now, and I expected to live another 45 hahahaha maybe but painless for the most part, so a week after the procedure and loosing 17 lbs, my knee pain is about 20% and I can go up the stairs without taking brakes, or using my left leg for support. The feeling was incredible. I’m still under little steps to gain energy back after the 1st week of liquids diet, and the exercise has to come also little by little, but I will highly recommend Dr. Portocarrero and his staff to everyone that has a problem with weight loss, but any other type of health problem can also do great with some lbs off, specially blood pressure, cholesterol, diabetes, eventually we will all get these problems so why not start controlling them without that much medication and just a great feeling of weight loss and energy.
    I’m only 17 lbs off now, but my goal is about 50 more lbs, I know I can do it, and having Dr. Portocarrero as a coach for a year to help me reach my goal makes me feel safe, he answers my questions and doubts, he helps me do better and encourage me to continue, given me tips of what can I eat and/or replace certain things, which on is better or healthier, which one you can eat more and which one a tiny piece hahahaha that will be hard, but at least I can have a little taste, just being able to rely on him and his staff makes me feel safe and immensely happy...
    Thank you so much Dr. Portocarrero, like you said, little by little but I know I will make my goal within a year💪🏾
