Your fears/my answers:
1. Going across the border: I wouldn't do that in my own vehicle without knowledge of the area. However, Dr. A's cousin Rosy picks you up in a van with a big sign on the side. She takes you down main streets until she gets to the hospital. Dr. A, his mom and Rosy's mom (Dr. A's aunt) live side by side less than a block from the hospital. I don't think Dr. A would live in an area or move his Mom into an area that was unsafe. The staff never let's you out of their site from the time they pick you up until you are safely delivered at the office/hospital.
Drug violence can hit anywhere. We were hiking in the woods near our property and found a working meth lab. If we had come across that while the "cookers" were there, we could've been murdered and left to rot in the woods. Mexico isn't the only dangerous place.
I read all the Justice department warnings about Mexico travel and I haven't seen one specifically for the town where Dr. A is. There are warnings for that state, further from the border but non right in his area.
2. The hospital was cleaner than some of the most famous medical mecca's here in the USA. I've been to Vanderbilt, John's Hopkins, and many other "famous" hospitals. None of them were as clean as Centro Medica. The hospital looked like a step back in time---looked like a hospital from the early 60's but the equipment used on me was the same stuff that is used in major hospitals here in the states.
I have had several surgeries in my life time and the VSG that Dr. A did for me was the ONLY time I have had surgery that I DIDN'T have a post op wound infection.
3. If you stick to the plan, follow the instructions given you, you will lose most if not all of your excess weight. The VSG is just a tool and how you use it is up to you. The more diligent you are, the more you will lose. Dr. A does surgery on high BMI patients. Your surgery will cost more (slightly higher charge for BMIs over 50 due to extra anesthesia and surgical time) but Susan, Dr. A's coordinator can fill you in on that. Contact Susan and she will guide you through the whole process. She will answer all your questions honestly.
Any other questions, pm me. My sleeve sister has lost over 110 lbs (she's 6 ft tall and was over 300 at the time of surgery). I've lost 94 lbs and I'm 50 years old. I would send any of my adult children, my husband or friends to Dr. A in a heart beat.
I never felt unsafe while I was there. I've been to Mexico when I did feel unsafe but not this time.
Never, never, never give up!
...though she be but little, she is FIERCE...
