AI Summary About 85% to 90% of adults with fatty liver disease (MASLD) have at least one metabolic comorbidity, and roughly a third have three or more.
Medically reviewed.
Liver disease rarely stays contained to the liver. Because the liver helps regulate fat, sugar, and hormone metabolism, damage to it is closely tied to conditions elsewhere in the body — and some of those same conditions can, in turn, make liver disease worse.
Metabolic dysfunction-associated steatotic liver disease (MASLD), the most common liver condition, is both a consequence and a driver of metabolic disease: most people diagnosed with it already have at least one other metabolic comorbidity. This page introduces the conditions most often seen alongside liver disease, why they are connected, and why coordinated care across specialists matters.

Metabolic comorbidities
These conditions share the same root causes as fatty liver disease — excess weight, insulin resistance, and abnormal blood fats — and often appear together at diagnosis.
Type 2 diabetes and liver disease have a two-way relationship. Long-standing type 2 diabetes can trigger insulin resistance, iron overload, oxidative stress, and inflammation that worsen liver disease, while liver disease raises the risk of developing type 2 diabetes. Type 1 diabetes is less directly tied to fatty liver disease but still calls for regular liver monitoring, since blood sugar swings affect the whole body.
Prediabetes means blood sugar is higher than normal but not yet in the diabetes range. MASLD prevalence runs 55% to 75% in people with type 2 diabetes, and prediabetes often marks an earlier point on the same path — making it a signal to address liver health before diabetes develops.
Carrying extra weight, especially around the abdomen, is one of the strongest risk factors for fatty liver disease. MASLD affects roughly 60% to 80% of people with obesity, and the risk climbs higher with severe or morbid obesity.
Cardiovascular disease is the leading cause of death in people with MASLD, responsible for about 40% of all deaths in this group. Impaired blood fat handling, blood vessel dysfunction, and body-wide inflammation from liver disease all raise heart disease risk, which is why heart screening is recommended for anyone with MASLD.
High blood pressure is one of the core features of metabolic syndrome, the cluster of conditions — along with obesity, high blood sugar, and abnormal cholesterol — that most often drives fatty liver disease. It also raises the risk of heart disease and stroke in people who already have liver disease.
Dyslipidemia means unhealthy levels of cholesterol or triglycerides in the blood. It frequently accompanies fatty liver disease and insulin resistance, and it adds to the elevated cardiovascular risk that comes with liver disease, which is why lipid panels are part of routine monitoring.
Other comorbidities
Beyond the metabolic cluster, several other conditions are strongly linked to liver disease through shared inflammation, immune, or organ-system pathways.
Because liver disease and its comorbidities feed into each other, guidance recommends screening in both directions: people with fatty liver disease should be checked for heart disease, diabetes, and kidney function, and people with those conditions should be checked for liver disease. Bring your full history — including diabetes, blood pressure, cholesterol, sleep, and joint symptoms — to your liver specialist, and share your liver diagnosis with every other doctor you see. Coordinated care between your liver specialist, primary care provider, and any relevant specialists gives your whole care team the same picture.
Small, consistent daily habits for each comorbidity add up. Share what you are tracking — blood sugar, sleep, vision changes, or joint pain — with your liver specialist so your whole care team sees the same picture.
Many of the conditions on this page respond to the same lifestyle changes that support liver health: a balanced, lower-sugar diet, regular movement, and consistent sleep. Making these changes can help manage several comorbidities at once, not just the liver itself. A liver-friendly diet includes more fruits, vegetables, and whole grains, and less alcohol, sugary drinks, processed food, and sodium. Regular physical activity benefits metabolic health and liver fat, even without weight loss. Losing 3% to 5% of body weight can reduce liver fat, and a larger loss is often needed to improve inflammation and scarring. Sleep matters too. Aim for 7 to 9 hours a night, because poor sleep can affect how the liver makes glucose and processes insulin.
A liver-friendly eating pattern emphasizes vegetables, lean protein, and whole grains while limiting added sugar and processed food — the same pattern recommended for diabetes, high blood pressure, and high cholesterol.

Common questions
Yes. Liver disease, especially fatty liver disease (MASLD), shares root causes with several other common conditions — obesity, type 2 diabetes, high blood pressure, and high cholesterol are the most frequent. About 85% to 90% of adults with MASLD have at least one metabolic comorbidity at diagnosis.
Fatty liver disease and diabetes influence each other in both directions. Long-standing type 2 diabetes can worsen liver damage through insulin resistance and inflammation, while liver disease itself raises the risk of developing type 2 diabetes. MASLD affects an estimated 55% to 75% of people with type 2 diabetes.
Cardiovascular disease is the leading cause of death in people with MASLD, causing about 40% of all deaths in this group. This is largely because MASLD and heart disease share the same underlying metabolic syndrome — obesity, high blood sugar, and high blood pressure — which is why heart screening is recommended for anyone diagnosed with fatty liver disease.
Yes, this connection runs in both directions. Obstructive sleep apnea is up to 40% prevalent among people with fatty liver disease, and it can act as a risk factor for liver disease progression even without obesity present, because repeated drops in oxygen during sleep disrupt fat metabolism and increase liver inflammation.
Bring your full health history — diabetes, blood pressure, cholesterol, sleep issues, joint pain, and any autoimmune or digestive conditions — to every specialist visit, and share your liver diagnosis with your other doctors. Since these conditions influence each other, guidance recommends screening in both directions: liver patients should be checked for heart and metabolic conditions, and people with those conditions should be checked for liver disease.
Yes. Celiac disease is an autoimmune reaction to gluten, and it can raise liver enzymes. It can also contribute to liver conditions such as autoimmune hepatitis, primary biliary cirrhosis, primary sclerosing cholangitis, and fatty liver disease. Following a gluten-free diet can help bring liver enzymes back to normal in many cases. People with celiac disease should be screened for liver problems, and people with liver disease should be screened for celiac disease.
Yes. Chronic liver disease disrupts vitamin D and calcium balance and lowers the liver's output of bone-supporting proteins. This raises the risk of osteoporosis and joint pain, a pattern sometimes called hepatic osteodystrophy. Ask your doctor whether a bone density (DEXA) scan is right for you.
