Longevity and Functional Medicine Clinic

A longevity clinic is a medical practice that focuses on extending healthy lifespan. It uses advanced testing, such as biological age and organ function markers, to find risks early and build a personalized prevention plan. Next Health has offered longevity care in the DMV since 2001.

Biological age can be measured, and many patients improve their markers over time. Next Health uses DNA methylation testing to find your biological age and pace of aging, then retests to see how your body responds to treatment. Individual results vary.

Traditional medicine usually treats symptoms after a disease develops. Functional medicine looks for the underlying causes using detailed history and advanced lab testing. Next Health combines both, so each protocol is built from your lab results rather than giving every patient with similar symptoms the same treatment.

Functional medicine is a patient-centered approach that looks for the root causes of illness instead of treating symptoms alone. A functional medicine doctor reviews your history, lifestyle and advanced lab results to understand how your body systems interact, then builds a treatment plan for you. At Next Health, this approach is combined with conventional internal medicine.

A functional medicine doctor looks for the root causes of a health problem instead of treating symptoms alone. At Next Health, Dr. Habib reviews your history in a visit that lasts about an hour, orders advanced lab testing, and builds a treatment plan from your own results.

Functional medicine is practiced at major academic centers, including Cleveland Clinic, which opened its Center for Functional Medicine in 2014. A Cleveland Clinic study published in JAMA Network Open in 2019 found the functional medicine model was associated with improvements in patients’ health-related quality of life compared with primary care.
