Fatty liver disease, also known as hepatic steatosis or diffuse hepatic steatosis, refers to the accumulation of excess fat in liver cells. This condition arises when fat deposition in the liver exceeds 5% of its cells (hepatocytes). As the liver plays a crucial role in fat metabolism, excess fat can disrupt its function and lead to complications. Depending on its cause and progression, fatty liver disease may range from mild and reversible to severe, potentially resulting in permanent liver damage or failure.

Significance and Prevalence

Researchers project that within the next 10–20 years, fatty liver disease leading to cirrhosis may surpass hepatitis C and excessive alcohol consumption as the primary reason for liver transplants. Approximately 25% of the global population is estimated to have non-alcoholic fatty liver disease (NAFLD). The prevalence is notably high among individuals with obesity, diabetes, or hyperlipidaemia. Furthermore, an increase in cases of non-alcoholic steatohepatitis (NASH) suggests a rising risk of liver-related complications such as cirrhosis and cancer.

Types of Fatty Liver Disease

  1. Non-Alcoholic Fatty Liver Disease (NAFLD):
    1. Fat accumulation occurs without significant alcohol consumption.
    1. Divided into stages:
      1. Simple Fatty Liver (NAFL): Excess fat without inflammation.
      1. Non-Alcoholic Steatohepatitis (NASH): Fat, inflammation, and liver cell damage, potentially progressing to fibrosis and cirrhosis.
      1. Fibrosis: Formation of scar tissue in the liver due to inflammation.
      1. Cirrhosis: Permanent scarring, shrinking, and liver dysfunction, which may lead to liver failure or cancer.
  2. Alcoholic Fatty Liver Disease (AFLD):
    1. Arises from excessive alcohol consumption, which interferes with fat metabolism.
    1. Stages include:
      1. Steatosis: Fat accumulation without significant symptoms.
      1. Alcoholic Hepatitis: Inflammation causing symptoms like jaundice, nausea, and fever.
      1. Alcoholic Cirrhosis: Advanced scarring leading to liver failure.

Causes of Fatty Liver Disease

Fatty liver can result from:

  • Hyperlipidaemia: Excessive fat in the bloodstream due to conditions like obesity, diabetes, or inherited disorders.
  • Liver Cell Damage: Impairment caused by:
    • Chronic illnesses or malnutrition.
    • Alcohol consumption.
    • Toxins and drugs.
    • Acute conditions, such as during late pregnancy.

Symptoms of Fatty Liver Disease

Fatty liver disease often remains asymptomatic and is detected incidentally during routine blood tests or imaging. When symptoms occur, they may include:

  • Fatigue or low energy.
  • Loss of appetite.
  • Nausea and unintentional weight loss.
  • Discomfort in the upper right abdomen due to liver inflammation.

As the disease progresses to more serious conditions like hepatitis or cirrhosis, symptoms may include:

  • Yellowing of the skin (jaundice).
  • Skin itching.
  • Swelling in the lower limbs.
  • Abdominal bloating or fluid buildup.
  • Mental confusion.
  • Intestinal bleeding.

Complications

Untreated fatty liver disease can lead to:

  • Liver fibrosis and cirrhosis.
  • Increased risk of liver cancer (hepatocellular carcinoma).
  • Liver failure, requiring transplantation.

Prevention and Management

Fatty liver disease can often be prevented or managed through early intervention and lifestyle changes:

  • Healthy Diet: Consume a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Avoid saturated fats and processed foods.
  • Regular Exercise: Aim for at least 150 minutes of moderate-intensity physical activity per week.
  • Weight Management: Achieve and maintain a healthy weight.
  • Limit Alcohol: Reduce or abstain from alcohol consumption.
  • Monitor Chronic Conditions: Control diabetes, cholesterol, and blood pressure through medication and healthy living.

Fatty liver disease, although widespread, is manageable with timely lifestyle adjustments and medical guidance. Early diagnosis and a commitment to healthier habits can reverse the condition and prevent progression to more severe complications. If you’re concerned about your liver health, consult a healthcare provider for appropriate evaluation and care.

Fatty Liver Disease Symptoms in Females

Fatty liver disease is more prevalent in women due to hormonal fluctuations during pregnancy or menopause. The condition progresses gradually, often remaining unnoticed in its early stages. As it advances, women may experience:

  • Fatigue.
  • Discomfort in the upper abdomen.
  • Swelling in the legs or abdomen (oedema).

Routine medical checkups are essential for early detection and effective management.

Fatty Liver Grades

Fatty liver is classified based on the percentage of fat accumulation in the liver:

  1. Grade 1 Fatty Liver (Mild): Fat deposition ranges from 5% to 33%.
  2. Grade 2 Fatty Liver (Moderate): Fat accumulation is between 34% and 66%.
  3. Grade 3 Fatty Liver (Severe): Fat deposition exceeds 66%, often accompanied by liver enlargement (hepatomegaly).

Risk Factors

Several factors contribute to the risk of developing fatty liver disease:

  • Non-Alcoholic Fatty Liver Disease (NAFLD):
    • Obesity.
    • Diabetes mellitus or insulin resistance.
    • High cholesterol levels (hyperlipidaemia).
    • Hypertension and metabolic syndrome.
    • Poor dietary habits.
    • Hypothyroidism and hypopituitarism.
    • Genetic predisposition.
  • Alcoholic Fatty Liver Disease (AFLD):
    • Regular consumption of alcohol (40-80g/day for 10-12 years).
    • Female gender (higher risk at lower alcohol consumption levels).
    • Pre-existing conditions like hepatitis C.

The rising prevalence of obesity globally further intensifies the risk of fatty liver disease.

Complications

Fatty liver disease can lead to severe health issues, depending on its type:

  • Non-Alcoholic Fatty Liver Disease (NAFLD):
    • Hepatocellular carcinoma (liver cancer).
    • End-stage liver disease.
    • Cardiovascular complications.
  • Alcoholic Fatty Liver Disease (AFLD):
    • Spontaneous bacterial peritonitis.
    • Variceal bleeding.
    • Hepatorenal syndrome.
    • Portal vein thrombosis and liver cancer.

Diagnosis

Fatty liver disease is often diagnosed incidentally through routine tests. Diagnostic tools include:

  • Blood Tests:
    • Liver function tests (LFT), Fibrosis-4 (Fib-4), lipid profile, and iron levels.
    • Specialized panels like NAFLD fibrosis score (NFS) or enhanced liver fibrosis (ELF).
  • Imaging Tests:
    • Ultrasonography, CT scans, MRI, or transient elastography (FibroScan).
  • Liver Biopsy:
    • Considered the gold standard for assessing liver fibrosis.

Treatment

Treatment focuses on addressing underlying causes and risk factors:

  • Lifestyle Modifications:
    • Weight loss through regular exercise and a balanced diet.
    • Controlling diabetes, cholesterol, and blood pressure.
  • Pharmacological Interventions:
    • Vitamin E therapy, omega-3 fatty acids, GLP-1 agonists, and statins.
    • Bariatric surgery (for morbid obesity).
    • Liver transplantation (for advanced liver damage).

Prevention

Preventive measures include:

  • Maintaining a healthy weight (5%-10% reduction in body weight is beneficial).
  • Exercising regularly.
  • Eating a balanced diet rich in proteins, whole grains, and vegetables while limiting salt, sugar, and oil.
  • Controlling chronic conditions like hypertension, diabetes, and hyperlipidaemia.
