David Blyweiss, MD

Functional Medicine

Dr. David J. Blyweiss began his medical career as a clinical pharmacist in South Florida prior to earning his medical degree. These dual backgrounds allowed him to appreciate the relevance of conventional pharmaceutical and surgical treatments in acute-medical conditions, and to recognize where they fall short in managing patients who suffer from the chronic degenerative diseases of Western civilization.

Dr. Blyweiss became an early adherent and experienced practitioner of what would become known as “functional medicine.” He uses this matrix of systems biology to effectively manage and alleviate the symptoms related to the most “difficult-to-treat” conditions by addressing the underlying causes, allowing the body to heal itself. He is a national and international speaker on the latest topics of interest in integrative and functional medicine. Dr. Blyweiss is an adjunct faculty member at the Miller School of Medicine at the University of Miami.

March 2023 Cruise Classes:

The Gut Microbiome: Trillions of Friends You Never Knew You Had

New research comes out on an almost daily basis regarding the importance of the intestinal microbiome and how it affects our health. This presentation includes the most recent science-based information relating to intestinal health. The impact of what we eat, and how and why a plant-based diet keeps our gut bacteria nourished to maintain our general health and brain health, will be discussed. From gut to brain and back again, this lecture will provide useful information regarding prebiotics, probiotics, and criteria for their use. New research on microbiota transplants for inflammatory bowel disease and autism will also be discussed.


Keynote: Prescription Drugs –The Good, the Bad, and the Unintended Consequences

This presentation will begin with a brief walk through the history of the pharmaceutical industry and how its evolution into Big Pharma affects our health. The presentation, which includes information regarding recently approved drugs, will discuss the most common side effects of appropriately prescribed medication, the associated nutrient depletion, and adverse reactions that can occur with short- and long-term medication use. It will also cover what you can do to balance side effects.
