Dr. Ruan's bio

This content was provided by Dr. Ruan "Medicine has always been echoed in every aspect of my life. I was born in China into a family of Chinese medical doctors. I spent the earlier part of my childhood growing up on the floor above my grandfather's clinic in a rural coastal village in southeastern China. One day when I was 3 years old, I woke up, ran downstairs naked, picked up my grandfather's stethoscope and ran around to avoid being caught by my grandmother while my grandfather and all the patients in his waiting room laughed. A couple of weeks after I turned 7 years old, I moved to Houston, TX. It was a culture shock to be in a totally new country and a completely different culture. However It didn't take too long for me to learn the language and assimilate into an already diverse culture. I found that the best way I learned was to learn about everyone around me. Everyone had unique stories, came from different cultural backgrounds, and had fascinating views on life as they see it. It was at that time I began collecting stories. These stories inspired me to learn about everyone so that we can all rise together. I knew that when I grew up, I wanted to be an inspirer. My family always stressed on using food as medicine rather than pharmaceuticals. My mother always stressed getting enough vegetables and phytonutrients in us when we were sick. With every illness we had, we looked at our behaviors (lack of sleep, poor nutrition) to see what we did to make our immune system fail us in the first place. After attending medical school, I realized that the focus on nutrition was minimal. During my residency training, while I received some of the best medical training in New York City, I still lacked true knowledge in preventative care. I sought to learn how nutrition affects our bodies. I began my research in nutrition by studying the concepts of functional medicine, Chinese medicine, and buried my head in many nutrition journals. I found that many chronic diseases can not only be treated by optimizing nutrition, but they can also be reversed. In 2015 I noticed that by using the dietary recommendations by current guidelines, I had tremendous trouble in trying to get people off of medicine for Type 2 Diabetes. It was at this time I began creating my own diet plan for my own patients. My philosophy in practicing medicine truly lies in the focus on reversing chronic disease. Although not all chronic illnesses can be cured, we can focus on significantly improving our quality of life by working together to put an end to unnecessary suffering. Author In December of 2015, I noticed that whenever I refer my patients out for diabetes education, they would still have the same or even high blood sugars after the classes. At first I was convinced they weren't compliant with the plan. Then I looked a good hard look at the American Diabetic Association guidelines and thought that some modifications were needed if I wanted to teach people to reverse Type 2 Diabetes. I asked my friend, Mimi Chan, to help me write a book with recipes: http://a.co/3QellRa"

You schedule an appointment with him but when you get to his office discover you are really scheduled with one of his Registered Nurses. I complained but didn't get to meet him first visit. At the end of follow up visit I...more

This place is amazing! This is the first time I have been to a doctors office that spent more than 10 minutes with me just collecting frivolous details and then prescribe pills. Dr. Ruan and his staff want to know where the root of the problem stems from instead of just covering up with a pill. I...more
