Topics
Fatty liver disease is a condition characterised by the accumulation of excess fat in the liver. It is broadly classified into two types: non-alcoholic fatty liver disease (NAFLD) and alcohol-related fatty liver disease (ARFLD). While NAFLD is typically associated with metabolic risk factors such as obesity, insulin resistance, and type 2 diabetes, ARFLD is linked to prolonged and excessive alcohol intake.
However, fatty liver disease is not solely caused by alcohol or weight issues. It may also develop due to certain medications, viral infections such as hepatitis C, metabolic disorders, or even as a result of rapid weight loss or pregnancy. Genetic predisposition and environmental exposures can also influence its onset.
Individuals Most at Risk
Although fatty liver disease may affect anyone, some individuals carry a significantly higher risk due to lifestyle, health, or hereditary factors.
-
Excess Body Weight
Individuals who are overweight or obese, particularly those with central abdominal fat, are at elevated risk for both NAFLD and ARFLD.
-
Type 2 Diabetes and Insulin Resistance
Persistent high blood glucose levels and insulin resistance are closely linked to fat accumulation in the liver.
-
Metabolic Syndrome
Those with a combination of high blood pressure, increased triglycerides, and abdominal obesity face a markedly higher risk.
-
Elevated Cholesterol and Triglycerides
Imbalances in lipid profiles can contribute to liver damage and fat deposition.
-
Medication-Induced Risk
Certain drugs, such as corticosteroids, some chemotherapy agents, and antiviral medications, may adversely affect liver function.
-
Chronic Infections
Long-term infections, particularly hepatitis C, can lead to liver inflammation and subsequent fat build-up.
-
Rapid Weight Loss
Sudden and significant reductions in body weight may disrupt normal liver function and cause temporary fat accumulation.
-
Ageing
Although fatty liver disease may occur at any age, it is more frequently diagnosed in middle-aged and older adults.
-
Ethnic Background
Studies suggest a higher prevalence among Hispanic individuals, followed by non-Hispanic whites and Asian populations.
-
Family History
A hereditary tendency toward metabolic or liver disorders may increase susceptibility.
Recognising Symptoms of Fatty Liver Disease
In many cases, fatty liver disease presents with no early symptoms. This asymptomatic nature makes routine health screening important for those at risk. As the disease progresses, several physical signs may become apparent:
- Persistent fatigue or a general sense of malaise
- Discomfort or pain in the upper right abdomen
- Unintended and prolonged weight loss
- Yellowing of the eyes or skin (jaundice)
- Easy bruising or prolonged bleeding
- Dark-coloured urine or pale stools
- Itchy or irritated skin
- Episodes of nausea or vomiting
Preventing Fatty Liver Disease
Fatty liver disease is largely preventable through sustained lifestyle improvements. For those at risk, the following strategies are crucial:
-
Nutritional Balance
Emphasise a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Avoid processed foods, sugary beverages, and deep-fried meals.
-
Sustainable Weight Loss
If overweight, gradual and consistent weight reduction through dietary and physical activity changes can significantly reduce liver fat.
-
Regular Physical Activity
Aim for at least 150 minutes of moderate exercise per week, including activities such as walking, swimming, or cycling.
-
Limiting Alcohol Intake
Alcohol can be highly damaging to liver health. Reducing or eliminating alcohol consumption lowers the risk of liver complications.
-
Diabetes Management
Maintain stable blood glucose levels through a combination of dietary choices, exercise, and prescribed medications.
-
Monitoring Blood Pressure and Lipids
Keeping blood pressure, cholesterol, and triglyceride levels within healthy limits is essential to reducing liver stress.
-
Liver-Safe Practices
Refrain from self-medicating or using unregulated herbal supplements. Always consult a healthcare professional before starting any new medication.
-
Supplement Use Under Medical Advice
Certain supplements, such as vitamin E or omega-3 fatty acids, may support liver function but should only be taken with medical supervision.
Frequently Asked Questions
1. Can fatty liver disease resolve on its own?
In many cases, especially in the early stages, lifestyle changes such as improved diet and physical activity can reverse the condition.
2. Is fatty liver disease considered serious?
While initially mild, untreated fatty liver may progress to fibrosis, cirrhosis, or liver failure.
3. Do only overweight individuals get fatty liver disease?
No. Individuals with a healthy weight may still develop fatty liver due to genetic, medical, or infectious factors.
4. What methods are used to diagnose fatty liver disease?
Diagnosis typically involves blood tests, imaging such as ultrasound, and occasionally a liver biopsy to assess the extent of damage.
5. Can children develop fatty liver disease?
Yes. Increasing rates of childhood obesity and sedentary lifestyles have led to a rise in paediatric fatty liver diagnoses.
