Comprehensive Nonalcoholic Fatty Liver Disease Program

Highlights of Our Program  |  Our Team  |  Research  |  Contact Us

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the United States. Without treatment, it can cause significant liver damage. When scar tissue accumulates, the diagnosis is called NASH-related liver damage/cirrhosis (NASH stands for nonalcoholic steatohepatitis). To serve this growing patient population, we have established a dedicated program for the study and management of NAFLD.

Our program provides long-term care for all aspects of NAFLD and NASH, utilizing a variety of tools: genetic testing, imaging, experimental therapeutics in clinical trials, and behavior modification. We are nationally recognized for our multidisciplinary approach, including the experts in hepatology, gastroenterology, cardiology, endocrinology, internal medicine, bariatric surgery and nutrition. This dynamic approach allows us to offer comprehensive plans for the management of fatty liver disease.

Highlights of Our Program

Comprehensive Treatment

Our program develops new techniques to guide important lifestyle changes

  • Personal nutrition consultations as needed and determined by a consult
  • Widespread use of mobile apps to assist with motivation, accountability and awareness of exercise and nutrition goals
  • Detailed exercise counseling
  • Partnership with weight management centers to support patients who are obese or overweight
  • Collaboration with Columbia’s Center for Metabolic and Weight Loss Surgery for patients needing bariatric procedures to address obesity, improve diabetes and lower cardiac risk
  • Screening and enrollment in clinical trials
  • Strong emphasis on translational research leading to better treatment and cures
  • Seamless transition to transplant services if needed (all hepatologists are transplant certified)

Pathway to Care

Patients can expect the following sequence of steps in their care journey (as needed):

1. Intake Visit & Non-invasive Tests
  • Detailed history and physical examination
  • Weight loss groups and/or registered dietician referral
  • Blood tests
  • Genetic testing
  • Point of care testing (elastography, etc.)
2. Follow-up (In-person and Telehealth)
  • Medical and surgical weight loss clinic
  • Specialty referral (nephrologist, cardiologist, etc.)
  • Additional testing
  • Clinical trials
  • Genetic counseling
  • Liver transplantation

Noninvasive Approaches For Risk Assessment

We believe in mitigating the use of biopsies when possible and use noninvasive tests (NITs) to help evaluate risk and course of treatment for patients with NAFLD and NASH. NITs may include blood tests, imaging (elastography) and risk calculators. Our program is also developing best practices for NITs that guide medical professionals in the field.


Our commitment to community based education efforts extends from our local Washington Heights area to the international community. Empowering patients with health information augments our ability to deliver excellent care.

Genomics and Precision Medicine

We focus on integrated genomics and precision medicine, which means we are studying the environments, lifestyles and genetics of patients to better understand the biology of NAFLD and how to sustain wellness. In fact, we've served as one of the beta launch sites for National Institute for Health’s (NIH) All of Us Research Program. The program asks participants to share broad information about their lifestyle with researchers in order to further this effort. It also pursues the gathering of data on a more diverse patient population than has historically been captured.

In addition to national recruitment efforts for precision medicine, we are working closely with the Columbia Center for Precision Medicine and Genomics (CPMG) and the Institute for Genomic Medicine (IGM) to develop superior models for delivering genetic test results at our center so that patients have the best care experience possible.

IGM, CPMG and the Department of Biomedical Informatics (DBMI) have also teamed up with our computational geneticists and analysts to discover new genetic variants associated with liver disease at all stages. Once these computational and statistical methods are developed locally they are applied to other global datasets for an even greater understanding of liver disease.

Hepatocellular Carcinoma

In collaboration with a large and diverse number of partnering medical institutions, we have worked to better understand the development of the most common form of liver cancer, Hepatocellular Carcinoma (HCC), across all liver diseases. These efforts include specific attention to the relationship between HCC and NAFLD.
