📑 Table of Contents
🤔 What is Fatty Liver Disease?
Fatty liver disease (also called hepatic steatosis) is a condition where excess fat accumulates in the liver cells. Normally, the liver contains a small amount of fat, but when fat makes up more than 5-10% of the liver's weight, it's considered fatty liver disease.
The liver is the body's second-largest organ and performs hundreds of vital functions, including:
- Detoxification: Filters toxins from the blood
- Metabolism: Processes nutrients and medications
- Storage: Stores vitamins, minerals, and glycogen
- Production: Produces bile, proteins, and cholesterol
📊 Types of Fatty Liver Disease
🍷 Alcoholic Fatty Liver Disease (AFLD)
Caused by excessive alcohol consumption
- Can progress to alcoholic hepatitis
- Reversible with alcohol abstinence
- More common in heavy drinkers
🥗 Nonalcoholic Fatty Liver Disease (NAFLD)
Fatty liver not caused by alcohol
- Most common type
- Linked to obesity, diabetes, metabolic syndrome
- Can progress to NASH
🩸 NASH (Nonalcoholic Steatohepatitis)
NAFLD with inflammation and liver damage
- More aggressive form
- Can lead to cirrhosis
- Requires medical management
📈 Stages of Fatty Liver Disease
Stage 1: Simple Fatty Liver
Fat accumulation without inflammation. Generally reversible.
Stage 2: Steatohepatitis (NASH)
Fat accumulation with inflammation. Some liver cell damage.
Stage 3: Fibrosis
Scar tissue begins to form. Liver function may be affected.
Stage 4: Cirrhosis
Severe scarring, permanent liver damage. Risk of liver failure.
🔍 Causes & Risk Factors
Obesity
70-80% of obese people have NAFLD
Diabetes
Type 2 diabetes increases risk
Poor Diet
High sugar, processed foods
Sedentary Lifestyle
Lack of exercise
Genetics
Family history
Alcohol
Excessive consumption
Medications
Certain drugs can cause fatty liver
Metabolic Syndrome

🚨 Symptoms of Fatty Liver
⚠️ Fatty liver is often "silent" — most people have no symptoms in early stages!
When symptoms do appear, they may include:
Unexplained Fatigue
Persistent tiredness and weakness
Nausea & Loss of Appetite
Feeling sick, not wanting to eat
Unexplained Weight Loss
Losing weight without trying
Upper Right Abdominal Pain
Discomfort or fullness in the liver area
Jaundice
Yellowing of skin and eyes (advanced stages)
Easy Bruising & Bleeding
Impaired liver function
🩺 How Doctors Diagnose Fatty Liver
Diagnosing fatty liver disease involves several steps. Here's the comprehensive process:
Medical History & Exam
Reviews risk factors and checks for liver enlargement
Liver Function Tests
Blood tests for ALT, AST, ALP, bilirubin
Imaging Tests
Ultrasound, CT scan, or MRI to visualize the liver
FibroScan
Special ultrasound to measure liver stiffness
Liver Biopsy
Gold standard — removes tissue to confirm diagnosis
Exclusion of Other Causes
Testing for viral hepatitis, autoimmune, and metabolic causes
🩺 Key Diagnostic Tools
- Liver Function Tests: Elevated ALT and AST indicate liver damage
- Ultrasound: Shows fat accumulation in the liver
- FibroScan: Non-invasive method to check for fibrosis
- Liver Biopsy: The most accurate diagnostic tool
