Eric Chan, ND and Tawnya Ward, ND are naturopathic doctors living and working in Richmond, BC. Dr Chan, ND graduated from UBC with a BSc and then went on to study at the Canadian College of Naturopathic Medicine in Ontario, graduating with an ND in 2003.. Dr Ward, ND graduated from Dalhousie University and also studied at CCNM, graduating in 2004. They are licensed by the College of Complementary Health Professionals of BC.
Dr. Chan, ND has a practice focus on mold and infection related illness, pain management, and chronic fatigue. Because of his patient population, he has developed a strong special interest in biotoxin causes of chronic illness to help achieve health goals.
His patient population has become focused on those presenting with chronic fatigue syndrome, as well as neurological presentations with marked cognitive impairments, balance problems and problems with position sense, central nervous system hypersensitivity alongside autonomic hyperarousal, and often different pain syndromes.
He often will evaluate for, based on the history, any triggers to immune system and neurological hyper-arousal, including infections, mycotoxins (mold related illness), and environmental toxins. He also will discuss options to evaluate and try to restore balance to the excessive inflammation and CNS / autonomic hyperarousal that characterizes his patient base.
Dr. Ward, ND has an interest in using detoxification and environmental medicine in treating difficult cases, especially those presenting with multiple allergies and chemical sensitivities. Dr. Ward's practice focuses on the treatment of allergies, chemical sensitivities.
She enjoys working with identifying especially environmental triggers, be it of a toxin-type nature or hidden sensitivities to foods or agents in the environment.
Prescription Authority: Prescription medications within the scope of practice of Naturopathic Physicians in British Columbia may be prescribed to patients as clinically indicated. Potential advantages, disadvantages, risks and expected costs will be discussed. Both Dr. Ward, ND, and Dr. Chan, ND, have certifications in this.
Individualized Treatment Plans: All treatments and recommendations are recommended and given after consultation, physical exam and laboratory analysis as indicated. All intravenous and intramuscular treatments are individualized and compounded based upon the specifics of that patient’s case and presentation. Vitamins, minerals and other nutrients (vitamin C, calcium, magnesium, B-complex, B5, B6, B12, phosphatidyl choline, glutathione, etc) may be administered intravenously or intramuscularly, as indicated by case presentation.
Risks: Most treatments have potential risks, which will be discussed prior to administration. For example with intravenous nutrient therapies, extra caution should be taken in potassium depleting conditions and medications (e.g. taken potassium depleting medications; states of low potassium: potassium depleting diuretics, beta agonists, glucocorticoids, diarrhea, vomiting, malnourishment), as IV magnesium can potentially worsen low blood potassium levels (can increase risk of digoxin induced cardiac arrhythmias). Conditions in which magnesium may be omitted include Myasthenia gravis, urinary tract infections with elevated urinary phosphates, hyperparathyroidism. Lower nutrient doses may be used in mild to moderate renal insufficiency. The intravenous vitamin injections that contain magnesium may cause a sensation of heat. Low blood pressure and excessive heat may be associated with rapid injection, and higher dose of magnesium. Lower magnesium doses and slower injections (e.g. IV drip) may be indicated for those with lower blood pressure. Anaphylactic reactions to thiamine (B1) have been reported in the medical literature on the rare occasion. The intravenous vitamin/mineral injections tend to be hypertonic (concentrated, depending on dose of nutrients and how much sterile water, saline or dextrose solution in which they are diluted), thus tenderness, burning sensation at the injection site, vein irritation, phlebitis (vein inflammation) is possible. Often repositioning the needle in the vein or further diluting nutrients can help reduce or eliminate pain or irritation. Vitamin/mineral injections may often be given in additional fluid to make it less hypertonic/concentrated.
