Liver problems are increasingly common, especially with the rise of obesity and unhealthy lifestyles. One of the most frequent conditions is fatty liver. But is all liver fat dangerous? In this article, Dr. Osama El-Bahr, Associate Professor of Hepatology, Gastroenterology, and Endoscopy, explains the difference between simple fatty liver and nonalcoholic steatohepatitis (NASH), and how each condition is diagnosed and treated.
Simple fatty liver refers to fat accumulation in the liver cells without inflammation or tissue damage. It’s often asymptomatic and discovered incidentally during routine check-ups.
Common causes include:
Obesity and being overweight
High-fat diet
Insulin resistance
Lack of physical activity
According to Dr. Osama El-Bahr, this condition is highly reversible with proper lifestyle modifications and dietary changes.
NASH involves fat accumulation along with liver inflammation that can lead to tissue damage, fibrosis, and cirrhosis over time.
Common symptoms of NASH include:
Chronic fatigue
Discomfort in the upper right abdomen
Abnormal liver function tests
Dr. Osama El-Bahr warns that if left untreated, NASH may progress to liver failure or liver cancer.
Factor | Simple Fatty Liver | NASH (Inflamed Fatty Liver) |
---|---|---|
Inflammation present | No | Yes |
Risk of fibrosis | Low | High |
Symptoms | Rare | Sometimes present |
Health risk | Low | High |
Potential for full recovery | High | Depends on early detection |
Dr. Osama El-Bahr emphasizes that early diagnosis is essential. Common tests include:
Liver function tests
Lipid and glucose profiles
Abdominal ultrasound
FibroScan to assess fibrosis
Liver biopsy in selected cases
Lose 7–10% of body weight
Follow a balanced, low-fat diet
Regular physical activity
Manage coexisting conditions like diabetes and high cholesterol
Avoid unproven herbal supplements
Dr. Osama El-Bahr strongly advises against using any medication or supplements without medical supervision.
Persistent abdominal pain
Abnormal liver test results
Family history of liver disease or obesity
Unexplained chronic fatigue
According to Dr. Osama El-Bahr, early detection and lifestyle changes can reduce the risk of complications significantly.
