Liver enzymes are essential proteins in the body that help the liver perform its functions, such as metabolizing medications and nutrients and making bile. Elevated liver enzymes can be caused by various diseases, medications, and conditions, including high blood pressure, high cholesterol, high blood sugar, and carrying excess weight around the midsection. People with metabolic syndrome may also have elevated liver enzymes.
Elevated liver enzymes (AST and ALT), often known as transaminases, are indicators of liver inflammation or injury. They may act as a warning that something is damaging your liver and should never be ignored. Obesity increases the risk of liver disease, as does eating unhealthy foods with excess fat or sugar. High levels of liver enzymes in the blood may be temporary or a sign of a medical condition like hepatitis or non-alcoholic fatty liver disease (NAFLD). Obesity can cause non-alcoholic fatty liver disease (NAFLD), characterized by excessive liver fat accumulation, leaving obese individuals and those with metabolic syndrome at increased risk of elevated liver enzymes.
Fatty liver disease is a build-up of fats in the liver that can damage the organ and lead to serious complications. Risk factors include obesity, a high-fat diet, and conditions like diabetes or polycystic fatty liver disease. Metabolic dysfunction-associated steatotic liver disease (MASLD) is a type of steatosis caused by factors other than excessive alcohol use.
An association between weight loss agents and liver enzyme elevation in men has been observed, particularly for traditional herbal medicines and dietary supplements. It tends to develop in people who are overweight or obese, particularly if they have a lot of fat around their waist. Some evidence also shows that liver enzymes may transiently increase immediately after a dietary-induced weight loss.

Can being overweight cause liver enzymes to be high?
Studies have shown that obesity may be associated with liver diseases, such as non-alcoholic liver diseases (NAFLD). A study on 1168 Indian people found that NAFLD was higher in people with BMI higher than 25 kg/m2. Increased levels of hepatic enzymes, including ALT, AST, and GGT, are more common in people with obesity. Serum GGT showed a significant association with both general and abdominal obesity. However, no direct association was found between these liver enzymes with obesity.
The underlying mechanisms of the possible association between obesity and serum liver enzyme levels are not yet clear. Elevated liver enzymes in women with overweight and obesity can be associated with weight-related hormonal disorders such as polycystic ovary syndrome and higher levels of free androgen and total testosterone. The effect of obesity on diabetes is partly mediated by GGT and ALT but not AST. Obesity may increase DNA methylation in liver tissue by increasing oxidative stress, leading to liver tissue destruction. Visceral adipose tissues secrete proteins such as adipokines, resistin, leptin, visfatin, and tumour necrosis factor α, which can influence liver function and lead to inflammation, cirrhosis, and hepatocellular cancer.
However, there are several factors that may mutually affect obesity and liver function, such as dietary intake. The present study found no significant association between BMI and liver enzymes after adjustment for calorie and macronutrient intake, suggesting that macronutrient and calorie intake may be the main cause of impaired liver enzyme serum levels. Further longitudinal studies on both genders using different liver function biomarkers are needed to determine the effects of obesity on liver function in adults and to discover the underlying mechanisms.
Can high ALT be nothing?
It’s important to know that having a high ALT test result doesn’t necessarily mean you have a medical condition. Less than 5% of people with elevated ALT levels have severe liver conditions. Other factors can affect your ALT levels. Your provider will take into consideration several factors, including other blood test results and your medical history, when analyzing your results.
What does it mean if my alanine transaminase (ALT) is low?. Having a lower than normal ALT result is uncommon and usually isn’t a cause for concern. However, a lower than normal ALT level could indicate a vitamin B6 deficiency or chronic kidney disease.
If your ALT result is lower than what’s considered normal, your healthcare provider will likely have you retake the test or undergo further testing to make sure nothing is causing your low level.
Can elevated liver enzymes be nothing?
What does it mean to have elevated liver enzymes?. If you have high levels of liver enzymes in your blood, you have elevated liver enzymes. High liver enzyme levels may be temporary, or they may be a sign of a medical condition like hepatitis or liver disease. Certain medications can also cause elevated liver enzymes.
What are liver enzymes?. Liver enzymes are proteins that speed up chemical reactions in your body. These chemical reactions include producing bile and substances that help your blood clot, breaking down food and toxins, and fighting infection. Common liver enzymes include:
- Alkaline phosphatase (ALP).
- Alanine transaminase (ALT).
- Aspartate transaminase (AST).
- Gamma-glutamyl transferase (GGT).
How do you know if you have too much fat in your liver?
Imaging procedures, including an ultrasound, CT scan (computed tomography scan) or MRI (magnetic resonance imaging), to check your liver for signs of inflammation and scarring. They may order a specialized ultrasound called FibroScan® to learn the amount of fat and scar tissue in your liver.
What is steatotic (fatty) liver disease?. Steatotic liver disease (SLD) includes several conditions associated with steatosis in your liver. “Steatosis” is a term healthcare providers use to describe fat buildup in an organ (usually your liver). A healthy, high-functioning liver contains a small amount of fat. Fat buildup becomes a problem when it reaches over 5% of your liver’s weight.
Why was fatty liver disease renamed steatotic liver disease?. Previously, steatotic liver disease was known as “fatty liver disease.” In 2023, experts renamed the condition and its subcategories to reflect its causes more accurately. For example, while some conditions associated with fat composition in your body (like obesity ) can increase your risk of steatosis, there are several risk factors unrelated to weight or body mass index (BMI).
The renaming also avoids language that’s potentially stigmatizing toward people with SLD.
Does belly fat cause fatty liver?
We conclude that fat infiltration of the liver is well correlated with amount of abdominal fat. Fatty liver tends to be more strongly associated with VF compared to SF. In other words, if a non-obese patient exhibits fatty liver, the patient may in fact have visceral obesity. Likewise, not all patients who have a large amount of SF develop fatty liver.
Background. It has been generally recognized that fatty liver can often be found among obese people. However, we often experienced that the obese patient might always not show the fatty liver on the hepatic ultrasound or computed tomography (CT) examination.
Research frontiers. According to previous studies, fatty liver was found to be more strongly associated with visceral fat (VF) than subcutaneous fat, because of the portal venous drainage and endocrine effect of VF. In this study, the authors proved the result by CT.
Why are my liver enzymes elevated all of a sudden?
Elevated liver enzymes often are a sign of inflamed or damaged cells in the liver. Inflamed or injured liver cells leak higher levels of certain chemicals into the bloodstream. These chemicals include liver enzymes that may appear higher than usual on blood tests.
Can overeating raise liver enzymes?
Because an over-indulgent diet can significantly increase liver-enzyme levels, clinicians evaluating patients with elevated ALT levels should ask questions not only about alcohol intake but also about excessive food intake.
Can losing weight reduce ALT?
Lowering ALT levels will depend on what is causing the elevation. In some instances, a person may lower ALT levels naturally by managing their weight, increasing their activity levels, and making diet changes.
However, when high ALT levels result from more serious underlying conditions, medical treatment may be necessary to reduce levels.
With proper treatment and lifestyle modifications, elevated ALT levels can return to a normal baseline.
What would cause a temporary spike in liver enzymes?
Common causes of elevated liver enzymes include: Nonprescription pain medicines, particularly acetaminophen (Tylenol, others). Certain prescription medicines, including statins, which are used to control cholesterol. Drinking alcohol.
Can you be healthy with elevated liver enzymes?
Key takeaways: Elevated liver enzyme levels can be a sign of serious liver disease. But they can also occur with mild, temporary illnesses. Symptoms of liver disease may not be present until later stages of severe disease.
Can eating too much fat cause liver problems?
- Fatty liver disease is a build-up of fats in the liver that can damage the organ and lead to serious complications.
- Risk factors include obesity, a high-fat diet, high alcohol intake and diabetes mellitus.
- In most cases, people with fatty liver disease are encouraged to modify their diets, take regular exercise and lose weight.
