No, you don't need drugs to improve your blood sugar, lose weight, or deal with PCOS. Yes, medications might seem convenient; however, this road goes nowhere. With time, your drug quantity will increase because these drugs can’t treat the causes of your problems. Based on the latest research, effective treatment of diabetes and PCOS can be achieved by working with gut microbiome. I use gut microbiome in my practice not only to lower insulin resistance and lower blood glucose but also for weight loss, getting regular periods, and improving the ability to conceive for girls with PCOS.

I am a Registered and Licensed Dietitian Nutritionist and a Board Certified Renal (Kidney) Nutrition Specialist. When I initially pursued a career in nutrition I was drawn to the idea that something as basic as food could have such a profound effect on health. Now my goal is to provide my clients with the most up-to-date nutrition advice backed by science, so they can feel empowered around food (even if they have a chronic disease). I was born and raised in north Florida and now reside in central Florida with my husband, son, and dog.
