Consultation Services
Dr. Cheng provides selected consultation services for individuals with complex chronic illness, metabolic dysfunction, cardiovascular risk, weight management challenges, cancer support needs, and healthy longevity goals.
Consultations are by appointment only and may include review of medical history, laboratory data, metabolic health markers, nutritional status, environmental factors, lifestyle patterns, and systems-level risk factors.
Consultation services are educational and integrative in nature and are not a replacement for emergency care or ongoing care with a primary physician or specialist.
IOM Systems Medicine
IOM Systems Medicine stands for Integrative Orthomolecular Systems Medicine. It is a root-cause, systems-level approach to understanding chronic disease, metabolic dysfunction, inflammation, oxidative stress, mitochondrial dysfunction, immune imbalance, environmental exposures, and impaired physiological resilience.
Instead of focusing only on isolated symptoms or single laboratory values, IOM Systems Medicine evaluates the broader biological terrain and seeks to restore metabolic, nutritional, mitochondrial, immune, endocrine, and vascular balance.
