Hola! Good evening to everyone from Lima, Peru
Finally we have a provider in South America as well. I found Dr Gupta on the IFM website and have already had the first consult with him for my mother's advanced cognitive decline. He has a very impressive resume and is from the Harvard School of Public Health (I think he has a clinic in the U.S. as well). He was very compassionate and took a lot of time explaining us the diet, supplements and tests. We had never heard of this thing called ApoE4 until last week - unfortunately awareness about this disease is still very poor in South America. If a doctor says "you have Alzheimer's" it's usually a death sentence. Dr Gupta is also helping my husband with his IBS. From what I can see so far, he is a very well-rounded Functional Medicine doctor. I'm going to recommend him highly to a lot of people!
Here's his website: https://www.dr-gupta.com/
addendum by slacker (moderator): Dr Gupta's website indicates that his primary practice is in Boston.
