Dig Deeper to Find Cause of Malaise

Dr. Julie’s column in your February/March 2013 issue prompted me to write. She was reviewing the case of a woman with fatigue and achiness driven by heavy metal toxicity in addition to food sensitivities and nutritional deficiencies. I’d like to echo her sentiment for health-care practitioners to dig deeper to find the cause of their patient’s malaise.

As the former GM of a functional medicine laboratory and medical center and someone who has battled chronic illness most of his adult life, I have become quite well versed in the treatment and causes of chronic illness. In fact, I donate much time, advising individuals who find me. They often need advice on where to go for treatment, what tests to ask their doctor for, or how to round out a treatment protocol. They are often failed even by alternative/integrative health-care providers either because the latter don’t do their homework and stay current, or only do salivary hormone assays, standard blood chemistries, food intolerance testing, and nutritional deficiency testing and don’t dig any deeper. This approach may work well for 80 of 100 patients, but the remaining 20 are not helped. As time goes on, this 80/20 situation is going to become more of a 50/50 situation as we are constantly bombarded with toxins in our air, food, water, and cosmetics.

The tests for digging deeper are available. Innovative labs such as Genova/Metametrix, Doctor’s Data, Cyrex, BioHealth, Diagnos-Techs, and IGeneX give health-care practitioners amazing tools to dig deeper into their patients’ health status. (Kudos to Metametrix for the Toxic Effects Core Panel; I look forward to the addition of flame retardant compounds to the panel.)

Regarding heavy metals, it is totally insufficient to look in a patient’s mouth for amalgams and inquire into known heavy metal exposures. So many patients have accumulated body burdens without even knowing it: the house that they grew up in, the city asphalt playgrounds, their summer job in the factory. A provocative challenge with a chelating agent should be done for those with neurological symptoms along with their fatigue and malaise. Current/ongoing exposure can be ruled in or out with a prechallenge collection or a prechallenge blood test.

My own heavy metals timeline will shed some light on this:

  • 1986: became chronically ill

  • 1987: approximately 15 dental amalgams removed

  • 1994: provocative challenge with EDTA – mercury and copper high, no discernible lead

  • 1994–1998: chelation with EDTA and later DMPS IV pushes, all heavy metals at low end of challenged reference range in late 1998

  • 2006: fatigue and neurological symptoms return, provocative challenge with DMSA shows huge lead load. Blood lead level prior to challenge very low. Throughout treatment in the 1990s, no significant lead load was ever detected.

Where are your Clinical Trials?

It has proven to be difficult, if not impossible, to proceed to full-scale randomized controlled trials (RCTs) for most of the natural methods that cannot be patented or otherwise monopolized.

  • The Midlife Women’s Health Summit: Evidence-Based Menopause Care in the Era of Longevity Medicine

    The Ritz-Carlton, Pentagon City 1250 S Hayes St, Arlington, VA, United States
    Hybrid Event

    Menopause Care in the Longevity Era Longevity medicine is everywhere right now. Supplements, protocols, influencer clinics, patients walking in with questions about interventions their doctors have never heard of. What's missing from most of it is the evidence. The Midlife Women's Health Summit is three days on what the research actually says about menopause care when you add a longevity lens. What works, what doesn't, what's being oversold, and what to tell the patient sitting in front of you. Co-chaired by Lisa Larkin, MD, FACP, MSCP, IF, Jen Gunter, MD, FRCS(C), FACOG, DABPM, ABPMR, and Lauren Streicher, MD, FACOG, MSCP; three of the clearest voices in women's health on separating data from marketing.

Exposure, Activity, Contribution: Reading Epstein-Barr Findings in the Individual Patient

Robert Lamberton, BSc, FNTP – Epstein-Barr virus accounts for roughly 2% of cancers worldwide, approaching 360,000 new cases and as many as 210,000 deaths each year, and about 95% of adults carry it. In the overwhelming majority, it causes nothing at all.

When a test for an agent is positive in nearly everyone, a positive test is not a finding. It is a background condition.

Before Gerson: The Forgotten Medical History of Coffee Enemas

By Scott Wilson – In 1875, Dr. J.P. Thomas wrote about using coffee enemas for opium and belladonna poisoning. He referred to cases going back to 1858 and 1859 and described coffee enemas as one of the ordinary means of treatment. That word “ordinary” stopped me. He wasn’t describing an experiment. He was describing something physicians already knew.
