My initial reason for consulting Dr. Balcavage was for hair loss. I was also having stomach/digestive problems and I was getting sick on a regular basis needing antibiotics regularly. The care that I received at Dr. Balcavage’s office improved my primary complaints as well as my overall health. As long as I take the current supplements recommend by Dr. Balcavage, my hair is no longer falling out. Following Dr. Balcavage’s diet and health recommendations has eliminated my stomach and digestive issues and I have not gotten sick or needed antibiotics. I would recommend Dr. Balcavage’s office to others. He has improved my quality of life exponentially! In my experience, if you put the work in following Dr. Balcavage’s instructions you will feel better!

After seeing few different doctors in a one year of what seemed like eternity, going through different detoxes, flushes, pills, being somewhat may be diagnosed, yet getting worse.. I finally found Dr. Balcavage. During our introductory meeting I was supposed to write down 5 things that I wanted him to help me with... those were 5 symptoms that lowered my quality of life, 5 symptoms that other doctors disregarded or told me I will have to deal with for the rest of my life. 4 months later, he did it! He fixed me! Finally, for the first time in very many years, I have no complaints!

There was a time that I thought I was in good health. After fighting with constant knee pain I was introduced to Dr Balcavage originally to ease joint discomfort. Once under his care the outcome changed my life. I didn't realize that for many years what I was eating was doing me more harm than good. Inflammation is only the tip of the iceberg with a host of other problems that are related to what we eat. I was in a secret agony. Under Dr Balcavage's care I was taught what to eat and what foods to avoid for better health. Together with supplements, that are based on real food not chemicals, combined with exercise and a healthy eating habits is the perfect combination to live by. I don't know where I'd be without the guidance of Dr Balcavage.

I have been a patient of Dr. Balcavage’s for a number of years, and I have always received exceptional and comprehensive care. He has changed my life by changing my health. He diagnosed me with celiac intolerance, which had greatly impacted my health, metabolism and digestion. By following his treatment protocol, I not only feel 100% better, but I also lost weight, which I have maintained for over a year. I highly recommend Dr. Balcavage, as he provides a holistic approach to ensure long- term good health.
