Both a naturopathic and a medical doctor are doctors, provide primary care, and are trained in many of the same areas of medicine, including human anatomy, microbiology, immunology, neuroscience, pharmacology, and biochemistry. Naturopathic doctors, however, treat patients as individuals and address more factors than just physical, such as environmental, emotional, and lifestyle.
Medical doctors tend to address symptoms and use pharmaceutical or surgical approaches, while naturopathic doctors use more natural, less invasive means of treatment.
