Diabetes and fatty liver disease: What’s the connection?

Key Takeaways:
- Diabetes and fatty liver disease are closely linked.
- People with Type 2 diabetes have a higher risk of developing fatty liver disease, which often has few or no symptoms.
- The same habits that help manage diabetes can protect your liver.
When you think about diabetes complications, you may think about your heart, kidneys, eyes or nerves. But there’s another organ that deserves attention: your liver.
People with Type 2 diabetes have a higher risk of developing a condition called metabolic dysfunction-associated steatotic liver disease, or MASLD. Formerly known as nonalcoholic fatty liver disease (NAFLD), MASLD occurs when too much fat builds up in the liver. It is often linked to Type 2 diabetes, overweight or obesity, high blood pressure and high cholesterol.
How are diabetes and fatty liver disease connected?
Your liver plays an important role in managing blood sugar. It stores extra glucose after you eat and releases it between meals and overnight to help give your body energy.
When you have Type 2 diabetes, your body has trouble using insulin effectively. This insulin resistance is closely connected to the development of MASLD. At the same time, having MASLD can make it harder for your body to regulate blood sugar.
In other words, diabetes and fatty liver disease can make each other harder to manage.
MASLD is common, but it often has no symptoms, especially in its early stages. It’s often diagnosed though a combination of blood tests, imaging studies and sometimes liver biopsy. That means you can have fat building up in your liver without knowing it. In some people, the disease can progress to a more serious condition called metabolic dysfunction-associated steatohepatitis (MASH), which causes inflammation and liver damage. Over time, this can lead to liver scarring, or cirrhosis, leading to the accumulation of nonfunctional tissue that impairs liver function.
What can you do to protect your liver?
The good news is that many of the same habits that help you manage diabetes can also support your liver.
Manage your blood sugar
Keeping blood sugar levels within your target range is an important part of protecting your overall health. Work with your healthcare team to create a diabetes management plan that works for you, including taking medications as prescribed and monitoring your blood sugar when recommended.
Work toward a healthy weight
If you are overweight or have obesity, even modest weight loss can benefit your liver. Losing about 5% to 10% of your body weight can reduce fat in the liver and may improve MASLD.
Focus on gradual, sustainable changes rather than quick fixes. Your health care team can help you set a realistic goal.

Choose foods that support both your blood sugar and liver
People with diabetes and MASLD do not need to follow one specific diet. Instead, they should focus on a balanced eating pattern that includes vegetables, fruits, whole grains, lean proteins and healthy fats.
Limiting added sugars, sugary drinks and foods high in saturated fat also helps. A Mediterranean-style eating pattern emphasizes this healthy balance of foods and is one helpful option that may benefit liver health.
Keep moving
Physical activity helps your body use blood sugar more effectively and can reduce the amount of fat stored in the liver.
The Centers for Disease Control and Prevention recommends at least 150 minutes of physical activity each week, but every bit of movement helps. If you haven't been active recently, start with an amount that feels manageable and gradually build from there.

Pay attention to your blood pressure and cholesterol
High blood pressure and high cholesterol are risk factors for MASLD and often occur alongside Type 2 diabetes. Managing these conditions, through a healthy lifestyle that includes plenty of exercise and a balanced diet, can help protect both your liver and your heart. Take medications as prescribed and talk with your healthcare team about your goals.
Limit alcohol
Alcohol can add stress to the liver because in the body, it produces toxic by‑products. If you have liver disease or are at risk for it, talk with your healthcare professional about whether you should avoid alcohol or limit how much you drink.
Don't wait for symptoms
Because MASLD often doesn't cause noticeable symptoms in its early stages, regular healthcare visits are important. Depending on your health history and risk factors, your provider may recommend blood tests or imaging to evaluate your liver.
If you have Type 2 diabetes, talk with your care team about your risk for MASLD and whether your liver should be screened.
Taking care of your diabetes isn't just about your blood sugar. It's also an important part of protecting your liver.
