Fatty Liver Disease

What is Fatty Liver Disease?

Fatty liver disease is a condition in which fat builds up in the liver. It is now usually called metabolic dysfunction-associated steatotic liver disease (MASLD), a newer name for non-alcoholic fatty liver disease (NAFLD).^{[1, 2]} It is defined by fat in at least 5% of the liver together with at least one metabolic risk factor such as obesity, diabetes, high blood fats or high blood pressure, and with little or no alcohol.^[1]

The condition is a spectrum. It ranges from simple fat to steatohepatitis (MASH, formerly NASH), in which the liver is inflamed and injured, and on to fibrosis, cirrhosis and liver cancer.^{[2, 3]}

Common symptoms

Fatty liver often causes no symptoms and is usually found through abnormal liver tests or an imaging scan done for another reason.^{[1, 3]} Fatigue or mild discomfort in the upper right abdomen can occur. Because it can stay silent while scarring develops, screening of people with risk factors matters.^[2]

Causes and risk factors

Fatty liver is closely tied to metabolic syndrome. It has a two-way association with obesity, high blood fats and type 2 diabetes, and diabetes raises the risk of cirrhosis.^{[1, 3]} Heavy alcohol use causes a related condition, alcohol-associated liver disease, and moderate alcohol with metabolic risk factors has its own category.^[1] Other causes include some medicines and genetic conditions.^[1]

How it is diagnosed and treated conventionally

Doctors suspect fatty liver from risk factors, liver enzyme tests or imaging, and then check for scarring with blood scores such as FIB-4 followed by imaging such as transient elastography.^[2] The aim is to find people with advanced fibrosis, who have the highest risk of liver complications.^{[2, 3]}

Treatment centers on lifestyle: weight loss, dietary changes, exercise and limiting alcohol, plus good management of diabetes, obesity and related conditions.^{[2, 3]} Bariatric surgery is an option for some people with obesity. For adults with MASH and significant fibrosis, the European guideline says a liver-targeted drug (resmetirom) should be considered where approved.^[2] Leading causes of death in fatty liver are cardiovascular disease and cancers outside the liver, so heart health is part of care.^[3]

Why Fatty Liver Disease calls for a whole-person approach

Fatty liver is a liver problem, but it grows out of how the whole body handles energy, fat and sugar. For this reason, treatment looks at weight, diet, movement, blood sugar, blood fats and blood pressure together, and combination treatment is likely to be needed for many people.^{[2, 3]}

Care that supports daily habits and metabolic health is therefore a reasonable companion to medical follow-up of the liver.

Weight, diet and physical activity

Healthy lifestyle and weight reduction remain the foundation of prevention and treatment.^[3] Guidelines advise weight loss, dietary change and regular exercise, and discourage alcohol.^[2]

Blood sugar and insulin resistance

Fatty liver and type 2 diabetes tend to occur together, and diabetes raises the chance of cirrhosis and its complications.^[3] Optimal management of diabetes and obesity is part of the guideline approach.^[2]

Cholesterol, blood pressure and heart health

High triglycerides, low HDL cholesterol and high blood pressure are among the metabolic risk factors used to define MASLD.^[1] Cardiovascular disease is a leading cause of death in people with fatty liver.^[3]

Alcohol

Alcohol intake changes the diagnosis: steatotic liver disease with moderate alcohol and metabolic risk factors is classed differently from MASLD, and heavy use counts as alcohol-associated liver disease.^[1] Guidelines discourage alcohol in MASLD.^[2]

Acupuncture for Fatty Liver Disease

What the research shows

The research on acupuncture for fatty liver is limited. Meta-analyses point toward benefit but rest on weak trials, and none compared acupuncture with a sham procedure as far as the abstracts state.

A 2021 meta-analysis of 8 randomized trials (939 patients) found that acupuncture, alone or added to conventional treatment, gave better overall clinical response rates and better liver enzymes and blood fats than conventional treatment alone, but not a lower body mass index. The authors cited insufficient methodological quality and sample size.^[4] A 2025 meta-analysis of 30 trials reported better clinical response, liver function, lipids and glucose with acupuncture, and called for large, rigorous trials to confirm this. It also reported benefit on liver fibrosis measures, which needs the same confirmation.^[5] A review of 16 trials of acupoint therapies found improved liver enzymes and blood fats, with the same caution.^[6]

One small trial of 50 women found that 6 weeks of electroacupuncture improved liver enzymes and triglycerides more than aerobic interval training, in addition to their usual medicines.^[7] None of these studies shows that acupuncture lowers the risk of liver complications over the long term.

How acupuncture may work

How acupuncture might affect liver fat in people is not established. The studies above mainly measured blood tests, and the review authors did not report an established mechanism.^{[4, 5]} In the trials, commonly used points included Taichong, Zusanli, Fenglong and Sanyinjiao.^[4]

What treatment involves

Treatment uses fine, sterile, single-use needles, usually left in place for about 20 to 40 minutes, sometimes with gentle electrical stimulation. The small electroacupuncture trial gave 3 sessions a week for 6 weeks.^[7] We reassess after a short course of visits.

Serious problems from acupuncture are rare. In prospective studies, about 9 in 100 patients had a minor reaction such as brief soreness or bleeding at a needle site, and serious events occurred in about 1 in 10,000 patients.^[8] Tell the practitioner first if you have a bleeding disorder, including from advanced liver disease, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine for Fatty Liver Disease

The Ayurvedic view

Ayurveda has no single classical name that matches fatty liver. Practitioners often describe it as an excess of Kapha and of Meda (fat tissue) with weak digestive fire (agni), sometimes with Pitta involvement in the liver. This is a traditional framework used to choose diet and lifestyle guidance, not a biomedical diagnosis.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Diet and daily routine aimed at reducing excess Kapha, such as regular meal times, less fried and sweet food, and daily physical activity
• Herbs and spices, such as turmeric (curcumin), triphala and bitter herbs, prescribed individually
• Transdermal medication therapy, in which an herbal preparation is applied to the skin
• Panchakarma cleansing therapies only where traditionally and medically suitable

Panchakarma is not appropriate during pregnancy, acute illness or frailty, and not for people with advanced liver disease or cirrhosis. Any such therapy should be cleared with your liver specialist first.

What the research shows

There are no clinical trials of Ayurvedic whole-system treatment or Panchakarma for fatty liver in the PubMed searches we ran. The Ayurvedic spice turmeric is the exception, because its extract curcumin has been tested on its own as a supplement in a placebo-controlled trial.^[9] Pooled analyses of curcumin trials also exist.^[10] That evidence is described in the next section.

Herbal medicine for Fatty Liver Disease

Herbs and formulas that have been studied

The best-studied herbal ingredients are curcumin from turmeric, berberine (found in several plants used in Chinese and Ayurvedic traditions), and silymarin from milk thistle.^{[10, 11, 12]} Chinese herbal formulas have been studied in many trials, with hawthorn fruit the most frequently used herb in a review of formulas.^[13] Xiaoyao Powder and Danning Tablet were the formulas highlighted in an evidence map.^[14]

What the research shows

The evidence is moderate for curcumin, but trials used concentrated supplements, not food spice. A meta-analysis of 16 trials with 1,028 participants found curcumin improved ultrasound findings, liver enzymes, cholesterol and body mass index.^[10] An umbrella analysis of 11 meta-analyses found lower AST, ALT, insulin resistance and body size measures, but called for higher-quality research.^[15] A 24-week double-blind trial of 80 people with simple fatty liver found curcumin reduced liver fat on a scan compared with placebo, along with weight and triglycerides.^[9]

Berberine reduced liver enzymes, blood fats and insulin resistance in a meta-analysis of 10 trials with 811 patients.^[11] For silymarin, a meta-analysis of 26 trials suggested improved enzymes and liver fat, but a 48-week placebo-controlled trial in 99 people with MASH confirmed by liver biopsy did not meet its main goal, although fibrosis measures improved in some.^{[12, 16]}

For Chinese herbal medicine, a review of 62 trials found modest benefit on enzymes and imaging compared with Western medicines.^[13] An overview of 37 systematic reviews found 35 were of low or critically low quality, and said clinical translation is not recommended on current evidence.^[14] None of these studies shows that herbs reverse liver scarring.

Safety and herb-drug interactions

Herbs can injure the liver, which matters in people who already have a liver condition. Herbal and dietary supplements account for about 20% of drug-induced liver injury in the United States, with green tea extract and multi-ingredient products among the main causes.^[17] Tell your liver specialist and us about every supplement before you start one.

Herbs can also interact with medicines, including warfarin and other drugs.^[18] In one study, about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[19] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, have cirrhosis or kidney disease, or take diabetes medicine, since some herbs also lower blood sugar.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine often describes fatty liver as stagnation of liver qi with spleen deficiency, phlegm and dampness, or blood stasis. Researchers studying this condition measure things that loosely parallel those ideas: insulin resistance, blood fats, liver enzymes and fat stored in liver cells.^{[4, 14]}

Ayurveda's excess Meda and weak agni resemble the modern picture of excess fat storage and disordered metabolism.^[1] No study has shown that a dosha or traditional pattern corresponds to a specific biological process.

How this care fits with your medical care

For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care. Keep your primary care doctor or liver specialist, and do not stop or change prescribed medicines for diabetes, cholesterol or blood pressure without your prescriber.

We do not diagnose or stage fatty liver or monitor liver scarring. Weight loss, healthy eating and exercise, which guidelines treat as the base of care, remain the priority.^[2] Please bring your diagnosis, recent liver tests and imaging or elastography results, a full list of medicines and supplements, and details of your alcohol use.

When to seek urgent medical care

Fatty liver can progress to cirrhosis, and some symptoms signal serious liver disease.^{[2, 3]}

• Yellowing of the skin or eyes
• Vomiting blood, or black, tarry or bloody stools
• Confusion, severe drowsiness or unusual behavior
• A rapidly swelling abdomen or leg swelling with severe abdominal pain
• Fever with abdominal pain
• Easy bruising or bleeding that is new

If any of these occur, call 911 or go to the nearest emergency department.
