Is Your Weight Affecting Your Liver?
Metabolic Liver & FibroScan Program
Fatty liver disease is common in people who are overweight or have diabetes, high cholesterol, high blood pressure or other metabolic conditions. It can also progress quietly, without obvious symptoms.
Gastroenterology of Westchester offers specialized evaluation for fatty liver disease, including FibroScan testing, to help assess liver fat, liver stiffness and the risk of fibrosis.
Our Metabolic Liver & FibroScan Program serves patients in Yonkers and throughout Westchester County who have known fatty liver disease, abnormal liver tests or metabolic risk factors that may affect liver health.
Understanding Fatty Liver Disease and MASLD
Fatty liver disease occurs when excess fat builds up in liver cells. In many patients, it is closely associated with obesity, type 2 diabetes, insulin resistance, high cholesterol and high blood pressure.
The condition is now medically known as metabolic dysfunction-associated steatotic liver disease, or MASLD. You may also see the older terms NAFLD or nonalcoholic fatty liver disease in medical records or online.
For some patients, fatty liver remains mild. In others, inflammation and scarring can develop over time. This scarring is known as fibrosis, and advanced fibrosis can lead to cirrhosis and other serious liver complications.
Because fatty liver and fibrosis often cause few or no symptoms early on, evaluation may be important even when you feel well.
Who May Benefit from a Liver Evaluation
A fatty liver evaluation may be appropriate if you have:
- Obesity or significant excess weight
- Type 2 diabetes or prediabetes
- High cholesterol or triglycerides
- High blood pressure
- Metabolic syndrome
- Fatty liver found on an ultrasound, CT scan or MRI
- Elevated ALT, AST or other abnormal liver blood tests
- Other risk factors for liver disease
Patients are also commonly referred after a primary care physician, endocrinologist or other healthcare provider identifies fatty liver or becomes concerned about metabolic risk factors.
Having fatty liver does not automatically mean serious liver damage is present. An important part of the evaluation is determining whether there are signs of fibrosis and whether additional monitoring or treatment is needed.
FibroScan Testing for Liver Fat and Fibrosis
FibroScan is a quick, noninvasive liver test that helps assess both liver fat and liver stiffness.
The test can provide two useful measurements:
- Liver stiffness, which may indicate fibrosis or scarring
- Controlled Attenuation Parameter, or CAP, which helps estimate the amount of fat in the liver
FibroScan uses vibration-controlled transient elastography and does not require needles, sedation or endoscopy.
These measurements can help your gastroenterologist better understand the condition of your liver and determine whether further evaluation is appropriate.
What to Expect During a FibroScan
During a FibroScan test, you lie on your back while a small probe is placed against the skin over the liver.
The device sends gentle vibrations through the liver and records measurements of liver stiffness and fat. The test itself usually takes only a few minutes and is generally painless.
No sedation is required, and patients can typically return to their normal activities afterward.
How FibroScan Differs From an Ultrasound
An abdominal ultrasound and a FibroScan provide different types of information.
An ultrasound may show that fat is present in the liver and can identify certain structural abnormalities. However, it does not provide the same type of liver stiffness measurement as FibroScan.
FibroScan is specifically designed to assess liver stiffness and estimate liver fat. This can help determine whether a patient appears to be at lower risk or whether there may be signs of significant fibrosis that require closer follow-up.
FibroScan does not replace every other liver test. Your physician may interpret the results along with blood work, medical history and previous imaging.
A Comprehensive Metabolic Liver Evaluation
The goal of a metabolic liver evaluation is not simply to confirm the presence of liver fat. It is to determine how your metabolic health may be affecting the liver and whether there are signs of progressive liver disease.
Depending on your medical history, your evaluation may include:
- Review of previous liver blood tests
- Review of ultrasound, CT or MRI findings
- Assessment of diabetes, cholesterol, blood pressure and other metabolic risk factors
- Review of medications and alcohol use
- Noninvasive fibrosis risk assessment
- FibroScan testing when appropriate
- Evaluation for other potential causes of liver disease
- Recommendations for monitoring, treatment or additional testing
This approach helps distinguish patients who may need routine follow-up from those who require more active liver-focused care.
Treatment and Management of Fatty Liver Disease
Fatty liver disease can often improve, particularly when it is identified before advanced liver damage develops.
Treatment depends on the severity of the liver disease and the metabolic conditions contributing to it. Recommendations may include:
- Weight reduction when appropriate
- Changes in diet and physical activity
- Improved control of diabetes
- Management of cholesterol and triglycerides
- Blood pressure control
- Medication when clinically appropriate
Weight management may be an important part of treatment, but this is not a general weight-loss program. The focus is on evaluating and protecting liver health.
If weight loss or medication may help improve your liver condition, we will discuss the options with you and coordinate appropriate treatment with your healthcare team.
Coordinating Care with Your Primary Care Physician
Metabolic liver disease often overlaps with primary care, endocrinology and other areas of metabolic health.
Our goal is not to replace your primary care physician. We focus on the liver-specific effects of obesity, diabetes and related conditions.
After your evaluation, we can provide results and recommendations to your primary care physician or referring provider so that care can be coordinated appropriately.
Patients at lower risk may continue routine metabolic management with their primary care doctor, while patients with signs of significant fibrosis or other liver abnormalities may need closer gastroenterology follow-up.
