A New Model of Care: Treating the Person Treats the Problem

By Crystal McCullough

Spot treating is for carpets, not people. Yet in many modern healthcare settings, medical issues are approached as isolated problems, addressed in a silo rather than in context of the person as a whole. What's exciting and beginning to shift, however, is the growing understanding that health is dependent on interconnected systems, behaviors, and environments.

For Dr. Rabih Nemr, board-certified bariatric and general surgeon at Park Slope Comprehensive Medical Wellness, that shift is foundational for the future of healthcare. The human body is not a fragmented system. Care is built around treating the whole person, prioritizing prevention, personalization, and a deeper understanding of the body as a whole.

Systemic Equilibrium

Preventive health begins with physiological balance. Most people have probably heard the phrase, "Stress is a silent killer." Central to combating this is the regulation of the autonomic nervous system (ANS), which is critical to functions such as heart rate, digestion, and stress response.

This system is the body’s version of yin and yang: two opposing forces that have to remain in equilibrium for optimal function. In Western medical terms, we see it as the balance between the sympathetic (“fight or flight”) and parasympathetic (“rest and digest”) systems. Often because of stress, poor nutrition, and/or inactivity, chronic sympathetic activation can contribute to disease.

Maintaining a balanced nervous system may be one of the most important steps a person can take to protect their health. It takes lifestyle recalibration centered on nutrition, functional training, effective weight management, and mindfulness practices, related factors that reinforce each other.

Patients who understand how these systems work and work together have a better chance in making decisions that support long-term outcomes, rather than short-term fixes.

Decoding Risk

A cornerstone of both prevention and treatment is the understanding of personal risk factors. Dr. Nemr encourages breaking risk down into two categories: fixed and modifiable.

Fixed risk factors (age, sex, family history) establish your baseline. They cannot be changed, but they provide context. Modifiable risk factors (diet, exercise, smoking, alcohol consumption) come with more leverage, where changes can alter outcomes. Quantifying individual risk factors into these categories turns a vague concern into action.

When patients understand which variables they can change and how lifestyle modifications affect them, they are more likely to engage in healthier behaviors.

Screenings as Strategy

Preventive screenings are underutilized, but they are one of the most effective tools in modern medicine. Many patients dread check-ups and regular screenings, but let’s reframe them as less of a burden and more an advantage - a chance to detect disease early or prevent it.

Standard preventive care screenings include colonoscopy, lipid panels, hemoglobin A1c testing, mammography, cervical cancer screening and more, each of which can be discussed with your medical team. And each provides critical insight into different aspects of health.

What if we went beyond conventional measures? Waist circumference, VO₂ max, and mobility are health indicators that offer additional layers of data into overall cardiometabolic and long-term health. Waist circumference gives clues about central obesity and metabolic regulation. VO₂ max helps us understand aerobic capacity and endurance. And both are strong predictors of health outcomes. Often overlooked, mobility assessments can be indicators of functional independence and musculoskeletal health, particularly as patients age.

A few extra minute, some targeted questions, and specific metrics shift care from reactive care to proactive. Together, clinicians and patients can identify risk earlier, intervene more effectively, and adequately track progress.
