Fatty Liver Without Alcohol: All You Need To Know

Dr.Sharad Malhotra, 7 mins read

You don't drink, you eat home-cooked food, but the ultrasound report mentions fatty liver grade This is where the misunderstanding begins. Fatty liver disease is often associated with alcohol; however, the majority of cases have nothing to do with it. Fatty liver without alcohol consumption is now one of the most frequent liver diseases in the world, often remaining asymptomatic for months or years.

This article talks about the condition of non-alcoholic fatty liver, what causes it, which fatty liver symptoms to look out for, and what steps can be taken to reduce the risk.

What Is Fatty Liver Without Alcohol?

Fatty liver implies that there is an abnormally high amount of fat in the liver cells. The liver typically stores a small amount of fat; however, anything above 5% of the total weight of the liver is considered to be fatty liver.
When it occurs in non-drinkers, it is called non-alcoholic fatty liver disease or NAFLD. In 2023, international liver societies adopted a new term, MASLD (metabolic dysfunction-associated steatotic liver disease) for this condition due to its strong association with metabolic problems like obesity, diabetes, and high cholesterol. Both terms essentially refer to the same condition, with NAFLD still being used frequently by Indian physicians.

There are two types of non-alcoholic fatty liver:

• Simple fatty liver: accumulation of fat in the liver cells without significant inflammation
• MASH (previously NASH): fat accumulation along with inflammation and liver cell injury, which can lead to cirrhosis / Liver Failure.

Fatty Liver Causes: What Triggers It in People Who Do Not Drink?

Insulin resistance is the key factor in the development of fatty liver. The body's cells become less sensitive to the hormone insulin, leading the liver to produce and store more fat. Contributing factors include:

• Obesity and central adiposity
• Type 2 diabetes mellitus
• High triglycerides, low HDL ("good") cholesterol, high blood pressure (metabolic syndrome)
• Consumption of refined carbohydrates, sugary beverages, and junk food
• Physical inactivity
• PCOS, hypothyroidism, and obstructive sleep apnoea
• Severe crash dieting or rapid weight loss
• Medications such as long-term corticosteroids, tamoxifen, amiodarone, and methotrexate
• Genetic predisposition

Fatty liver can also develop in individuals who are not overweight, also referred to as lean fatty liver. South Asians have a higher risk of developing fatty liver, even with a normal body mass index due to increased visceral fat.

Fatty Liver Symptoms

The majority of fatty liver cases are asymptomatic, with the condition being discovered incidentally on an ultrasound scan or after routine blood tests. The most common symptoms, if present, are:

• Persistent and overwhelming fatigue
• Dull pain or discomfort in the right upper quadrant of the abdomen
• Fullness or discomfort after meals ( Especially Fatty Foods )
• Velvety, dark skin discolouration on the neck and under the armpits, which can be a sign of insulin resistance

In the advanced stages of cirrhosis, symptoms may include:

• Yellowing of the skin and eyes (jaundice)
• Swelling of the legs or abdomen
• Skin itching
• Easy bruising and bleeding
• Altered sleep patterns and confusion

Due to its asymptomatic nature, those with diabetes, obesity, or a history of liver disease should consider getting screening even in the absence of symptoms.

Can Fatty Liver Become Serious?

Simple fatty liver rarely progresses to cirrhosis. In a minority of cases, persistent inflammation causes fibrosis (scarring of the liver) that can lead to cirrhosis, liver failure, or rarely, liver cancer decades later.

Fatty liver patients have an increased risk of cardiovascular disease, which is frequently the greater danger in the long run. Doctors also recommend screening for cholesterol and blood pressure and blood śugar since these are additional risk factors for heart disease.

How Is Fatty Liver Diagnosed?

Your doctor will ask you about your medical history, alcohol consumption, and medications before conducting a physical exam. Tests that may be recommended include:

• Liver function tests (ALT, AST): these enzymes are often elevated in liver disease, but can also be normal in fatty liver
• Abdominal ultrasound: the first-line investigation for diagnosing fatty liver
• FibroScan: a non-invasive test that measures liver stiffness and the amount of fat
• Blood glucose, HbA1c, and lipid profile: to screen for diabetes and high cholesterol
• Liver biopsy: in certain circumstances to determine the stage of liver damage

Ultrasound classifies fatty liver on a scale of grade 1 (mild, least fat) to grade 3 (severe, most fat). Scanning alone cannot detect whether the liver has been scarred, which is why the FibroScan or liver biopsy may be necessary.

Fatty Liver Treatment: Ways To Reduce Your Risk

Lifestyle modifications are the cornerstone of fatty liver treatment. In early stages, they can result in a complete resolution of fatty liver.

• Gradual weight loss: losing just 5% of the body weight can reduce liver fat, 7-10% can reduce inflammation, and 10% or more can reduce the risk of fibrosis in certain cases
• Following a fatty liver diet: a liver-friendly, Mediterranean-style diet that is high in fruits and vegetables, whole grains, pulses, nuts, and healthy oils and low in processed foods, is most beneficial
• Regular exercise: at least 150 minutes of moderate-intensity activity a week
  Control of diabetes, cholesterol, and blood pressure: treating these metabolic conditions has a favourable effect on the liver
• Avoiding alcohol: drinking can exacerbate liver disease and is generally not recommended for those with fatty liver
• A liver detox or herbal supplements: certain bodybuilding supplements and herbal remedies can be harmful to the liver, so it's best to avoid them
• Getting vaccinated: those with chronic liver disease should be vaccinated against hepatitis A and B

Those with MASH and advanced fibrosis may also benefit from pharmaceutical or advanced therapies, depending on the individual case.

When Should You See A Doctor?

Consult a doctor if you have:

• A fatty liver detected on ultrasound
• Elevated liver enzymes on blood tests
• Diabetes, obesity, or PCOS with fatigue
• Persistent pain or discomfort in the right upper abdomen
• Yellowing of the eyes or skin or swelling of the abdomen (urgent evaluation required)

A gastroenterologist or hepatologist can help determine the severity of the condition and recommend appropriate treatment. At Aakash Healthcare, our gastroenterology department evaluates patients with fatty liver using the necessary investigations to determine the stage of disease.

Frequently Asked Questions

Can you get fatty liver without drinking alcohol?

Yes. Non-alcoholic fatty liver is one of the most common liver diseases and is strongly associated with insulin resistance and obesity.

• Occurs in people who drink little or no alcohol
• Strongly associated with metabolic syndrome
• Can occur in people of normal weight
• Often discovered incidentally on ultrasound

What are the early symptoms of fatty liver?

Most people with fatty liver do not experience symptoms. If symptoms occur, they are generally mild and vague.

• Fatigue
• Dull pain in the right upper quadrant
• Fullness or discomfort after meals
• Dark patches on the neck or under the armpits

Can fatty liver be reversed?

In the early stages, yes. Lifestyle changes such as a healthy diet and regular exercise can reduce liver fat and reverse the effects of the disease. Significant weight loss can also help in reducing inflammation and fibrosis.

• 5% weight loss reduces liver fat
• 7-10% weight loss reduces liver inflammation
• Exercise is beneficial even without weight loss
• Regular monitoring is important to track progress

What should I avoid eating with fatty liver?

A fatty liver diet includes avoiding foods that increase blood sugar and triglycerides.

• Sugary beverages and sweets
• Refined carbohydrates like white bread and maida
• Deep-fried and processed foods
• Excessive consumption of red and processed meats

Is fatty liver grade 1 dangerous?

Fatty liver grade 1 indicates a small amount of fat in the liver, which is often easily treatable. It is still important to undergo regular check-ups and lifestyle modifications, particularly if one has other risk factors for metabolic disease.

• Typically does not cause symptoms
• Can be improved with lifestyle modifications
• Can progress if other risk factors are present

Can thin people get fatty liver?

Yes. Lean individuals can also develop fatty liver, especially if they have PCOS or other risk factors for metabolic syndrome.

• Individuals with PCOS are at increased risk
• Lean fatty liver is more prevalent among South Asians
• Body mass index is not always an accurate indicator of liver fat
• It is important to get screened if one has risk factors

Which doctor should I see for fatty liver?

A gastroenterologist or hepatologist can evaluate the condition and recommend further management. Patients with diabetes or high cholesterol may also benefit from consulting an internal medicine doctor or diabetologist. A dietitian can help design a liver-friendly meal plan.

• Gastroenterologist or hepatologist: to evaluate liver function
• Internal medicine doctor: for overall management of metabolic syndrome
• Dietitian: to develop a healthy meal plan
• Cardiologist: if cardiovascular risk factors are present

Take Fatty Liver Seriously While It Is Still Reversible

Fatty liver without alcohol is a very common condition, with most cases being asymptomatic. The good news is that it is largely reversible with early intervention, which is why it's critical to get tested if one has risk factors. If you have a fatty liver, diabetes, obesity, or high cholesterol, or if your scan report mentions fatty liver, do not hesitate to consult the Gastroenterologist at Aakash Healthcare in Dwarka, New Delhi.
