An endocrinologist is a doctor who treats hormone and metabolism conditions, such as diabetes and thyroid disease. The liver helps process fats and sugars, so these conditions are closely tied to fatty liver disease.
Endocrinologists do not usually lead liver care. They treat the hormone and metabolic problems that often sit behind liver fat, and they work alongside your liver specialist.
This page explains what an endocrinologist does, which conditions and tests are involved, when to book a visit, and how to find one.

Overview
An endocrinologist is a doctor who specializes in endocrinology, the branch of medicine that focuses on hormones and metabolism. Hormones are chemical messengers that help control how your body uses energy. Metabolism is the way your body processes food, fat, and sugar. The liver helps process fats, sugars, and proteins, so hormone and metabolic conditions can affect liver health.
Role
Hormones and metabolism affect how your liver handles fat and sugar. An endocrinologist treats the hormone and metabolic conditions that often sit behind fatty liver disease. A hepatologist (liver specialist) or gastroenterologist usually leads care for the liver itself.
Care
Your plan depends on your hormone and metabolic health, and on how far any liver damage has gone. Your endocrinologist and liver specialist decide on treatment with you.
With insulin resistance, cells in your muscles, fat, and liver do not respond to insulin as they should. This is a main cause of metabolic dysfunction-associated steatotic liver disease (MASLD), the new name for fatty liver disease (formerly NAFLD). Fat buildup can lead to inflammation and scarring. Better blood sugar control is part of protecting your liver.
Thyroid hormones help your liver process fats, sugars, and proteins. When thyroid levels are low (hypothyroidism), the liver slows down, which can add to fatty liver and raise cholesterol. Symptoms such as tiredness, weight gain, and swelling can look like liver problems. A simple blood test (TSH, free T4, free T3) can tell them apart.
High blood fats and excess weight, especially around the belly, raise the risk of MASLD. Your endocrinologist can check your lipid levels, review your diet and activity, and discuss weight-management options with you.
GLP-1 medicines, such as semaglutide and tirzepatide, help manage type 2 diabetes and support weight loss. In a semaglutide trial for liver disease, the most common side effects were mild to moderate stomach symptoms like nausea and diarrhea. Rezdiffra (resmetirom) is a daily tablet approved by the FDA in March 2024 for metabolic dysfunction-associated steatohepatitis (MASH, formerly NASH) with moderate to advanced scarring (fibrosis stages F2 to F3) but no cirrhosis. It is not mainly a diabetes or weight-loss drug. Ask your care team which option fits you.
PCOS, low pituitary hormones (hypopituitarism), and low sex hormones (hypogonadism) can each raise the chance of fatty liver. Some medicines, including steroids, can also cause fat buildup in the liver. An endocrinologist can look for these causes and coordinate with your liver specialist on tests such as elastography to measure liver stiffness.
Services
Most endocrinology tests are simple blood draws. Your endocrinologist reviews the results with you and shares them with your liver specialist.
Diabetes is diagnosed with a hemoglobin A1C test (6.5% or higher) or a fasting blood glucose level of 126 mg/dL or higher on two separate occasions. If you have type 2 diabetes, your provider may test your A1C every 6 months when it is well controlled and every 3 months when it is not.
If you do not have diabetes, your doctor may estimate insulin resistance with HOMA-IR. This calculation uses your fasting glucose and insulin levels. It can help when the cause of liver fat is unclear.
A thyroid check is a simple blood test. It measures TSH, free T4, and free T3, and sometimes anti-TPO antibodies, which point to autoimmune thyroid disease. Doctors often include it in routine monitoring when you have liver disease or symptoms that do not match your liver results.
People with type 2 diabetes should have their cholesterol and triglycerides checked once a year. The same blood test is used to look for a metabolic cause of liver fat.
Type 2 diabetes care also includes blood pressure checks, kidney tests at least once a year, and foot, eye, and dental exams. Your endocrinologist may order some of these and refer you for the rest.
Your endocrinologist builds a plan around diet, activity, weight, and medicines. They also review your current medicines and work with your liver specialist on liver imaging and scar testing.
Timing
Fatty liver disease usually causes no symptoms, so it is often found through a blood test or ultrasound. It is common in people with type 2 diabetes: about 55% to 75% have it. Ask your doctor about an endocrinology referral if any of the situations below apply. Yellow skin or eyes, a swollen belly, or vomiting blood are liver warning signs. Get medical care right away if you notice them.
Comparison
These specialists often share care. Your primary care doctor can help you decide who to see first.
| Specialist | Main focus | Role in fatty liver care |
|---|---|---|
| Endocrinologist | Hormones and metabolism, including diabetes, thyroid, and cholesterol | Treats the metabolic and hormone conditions that drive liver fat |
| Hepatologist | The liver and its diseases | Leads care for liver scarring and complications |
| Gastroenterologist | The digestive system, including the liver, gallbladder, and bile ducts | Diagnoses and manages liver conditions, and refers you to a hepatologist when needed |
| Nutritionist | Food and eating habits | Helps you build a liver-friendly eating plan |
Severe liver symptoms, such as yellow skin or eyes, a swollen belly, or vomiting blood, need urgent medical care, not an endocrinology referral.
Your Visit
A little preparation helps your care team see the whole picture. Ask the office about any food or drink limits before the visit, since some blood tests need fasting.
First Visit
A first visit with an endocrinologist is usually a conversation, an exam, and blood tests. The exact steps depend on your health and your referral.
Ask your care team which tests you need and when to repeat them.

Common Questions
Not always. Your primary care doctor or a liver specialist often leads care for fatty liver disease. An endocrinologist helps most when you also have type 2 diabetes, a thyroid condition, PCOS, or blood sugar or cholesterol that is hard to control. Ask your doctor whether a referral makes sense for you.
An endocrinologist treats hormone and metabolic conditions, such as diabetes and thyroid disease. A hepatologist treats the liver itself, including scarring and complications. People with metabolic fatty liver disease often benefit from both, working together.
Yes, it can. Thyroid hormones help the liver process fats and sugars. Low thyroid levels (hypothyroidism) slow this work and can contribute to fatty liver and higher cholesterol. A blood test for TSH and free T4 can show whether your thyroid is involved.
Yes, type 2 diabetes raises your risk. Fatty liver disease is found in about 55% to 75% of people with type 2 diabetes. Because it usually causes no symptoms, ask your doctor about liver screening, such as liver blood tests or an ultrasound.
Possibly, but your doctor decides. GLP-1 medicines treat type 2 diabetes and support weight loss, and one semaglutide trial in liver disease reported mild to moderate stomach side effects as the most common. Rezdiffra is approved for MASH with moderate to advanced scarring but no cirrhosis. Never start or stop a medicine without talking to your care team.
