How Dr. Nghia Nguyen Diagnoses Fat Loss Issues
Dr. Nguyen uses a detailed evaluation process:
Medical History and Physical Exam
He begins by discussing your health history, diet, activity levels, and any recent or unexplained fat loss. A physical exam helps assess muscle and fat distribution.
Blood Tests
These tests check for hormone imbalances, cholesterol levels, thyroid function, and blood sugar to rule out medical causes of fat loss.
Body Composition Testing
Advanced tools are used to measure fat vs. muscle mass, helping identify whether the weight loss is healthy or concerning.
Metabolic Rate Assessment
Resting metabolic rate testing helps determine how many calories your body burns daily, guiding personalized nutrition and treatment plans.
